Proximity Sensors Technical Guide

●Design

Sensing Object Material

The sensing distance varies greatly depending on the material of the

sensing object. Study the engineering data for the influence of

sensing object material and size and select a distance with sufficient

leeway.

•In general, if the

sensing object is a non-

magnetic metal (for

example, aluminum),

the sensing distance

decreases.

Size of Sensing Object

In general, if the object is smaller

than the standard sensing

object, the sensing distance

decreases.

•Design the setup for an object

size that is the same or greater

than the standard sensing

object size from the graphs

showing the sensing object

size and sensing distance.

•When the size of the standard

sensing object is the same or

less than the size of the

standard sensing object,

select a sensing distance with

sufficient leeway.

Thickness of Sensing Object

•The thickness of ferrous metals

(iron, nickel, etc.) must be 1 mm

or greater.

•For non-magnetic metal, a

sensing distance equivalent to a

magnetic body can be obtained

when the coating thickness is

0.01 mm or less. With pulse-

response models (e.g., E2V),

however, the characteristics may

vary. Be sure to check the

catalog information for the

relevant model.

When the coating is extremely

thin and is not conductive, such

as a vacuum deposited film,

detection is not possible.

•Influence of Plating If the sensing object is plated, the sensing

distance will change (see the table below).

Effect of Plating (Typical)

(Reference values: Percent of non-plated sensing distance)

Mutual Interference

•Mutual interference refers to a state where a Sensor is affected by

magnetism (or static capacitance) from an adjacent Sensor and the

output is unstable.

•One means of avoiding interference when mounting Proximity

Sensors close together is to alternate Sensors with different

frequencies. The model tables indicate whether different

frequencies are available. Please refer to the tables.

•When Proximity Sensors with the same frequency are mounted

together in a line or face-to-face, they must be separated by a

minimum distance. For details, refer to Mutual Interference in the

Safety Precautions for individual Sensors.

Power Reset Time

A Sensor is ready for detection within 100 ms after turning ON the

power. If the load and Sensor are connected to separate power

supplies, design the system so that the Sensor power turns ON first.

Proximity Sensors Technical Guide

Turning OFF the Power

An output pulse may be generated when the power is turned OFF, so

design the system so that the load or load line power turns OFF first.

Influence of Surrounding Metal

The existence of a metal object other than the sensing object near the

sensing surface of the Proximity Sensor will affect detection perfor-

mance, increase the apparent operating distance, degrade tempera-

ture characteristics, and cause reset failures. For details, refer to the

influence of surrounding metal table in Safety Precautions for individ-

ual Sensors.

The values in the table are for the nuts provided with the Sensors.

Changing the nut material will change the influence of the surrounding

metal.

Power Transformers

Be sure to use an insulated transformer for a DC power supply. Do

not use an auto-transformer (single-coil transformer).

Precautions for AC 2-Wire/DC 2-Wire Sensors

Surge Protection

Although the Proximity Sensor has a surge absorption circuit, if there

is a device (motor, welder, etc.) that causes large surges near the

Proximity Sensor, insert a surge absorber near the source of the

surges.

Influence of Leakage Current

Even when the Proximity Sensor is OFF, a small amount of current

runs through the circuit as leakage current.

For this reason, a small current may remain in the load (residual

voltage in the load) and cause load reset failures. Verify that this

voltage is lower than the load reset voltage (the leakage current is

less than the load reset current) before using the Sensor.

Using an Electronic Device as the Load for an AC 2-Wire

Sensor

When using an electronic device, such as a Timer, some types of

devices use AC half-wave rectification. When a Proximity Sensor is

connected to a device using AC half-wave rectification, only AC half-

wave power will be supplied to the Sensor. This will cause the Sensor

operation to be unstable. Also, do not use a Proximity Sensor to turn

the power supply ON and OFF for electronic devices that use DC half-

wave rectification. In such a case, use a relay to turn the power supply

ON and OFF, and check the system for operating stability after

connecting it.

Examples of Timers that Use AC Half-wave Rectification

Timers: H3Y, H3YN, H3RN, H3CA-8, RD2P, and H3CR (-A, -A8, -AP,

-F, -G)

Countermeasures for Leakage Current (Examples)

AC 2-Wire Sensors

Connect a bleeder resistor to bypass the leakage current flowing in

the load so that the current flowing through the load is less than the

load reset current.

Calculate the bleeder resistance and allowable power using the

following equation.

P : Watts of bleeder resistance (the actual number of watts

used should be several times this number)

I : Load current (mA)

It is recommend that leeway be included in the actual values used.

For 100 VAC, use 10 kΩ or less and 3 W (5 W) or higher, and for 200

VAC, use 20 kΩ or less and 10 W (20 W) or higher. If the effects of

heat generation are a problem, use the number of watts in

parentheses ( ) or higher.

DC 2-Wire Sensors

Connect a bleeder resistor to bypass the leakage current flowing in

the load, and design the load current so that (leakage current) × (load

input impedance) < reset voltage.

Calculate the bleeder resistance and allowable power using the

following equation.

P : Watts of bleeder resistance (the actual number of watts

used should be several times this number)

iR: Leakage current of Proximity Sensor (mA)

iOFF : Load reset current (mA)

It is recommend that leeway be included in the actual values used.

For 12 VDC, use 15 kΩ or less and 450 mW or higher, and for 24

VDC, use 30 kΩ or less and 0.1 W or higher.

Proximity Sensors Technical Guide

Loads with Large Inrush Current

Loads, such as lamps or motors, that cause a large inrush current* will

weaken or damage the switching element. In this situation, use a

relay.

*E2K, TL-N@Y: 1 A or higher

●Mounting

Mounting the Sensor

When mounting a Sensor, do not tap it with a hammer or otherwise

subject it to excessive shock. This will weaken water resistance and

may damage the Sensor. If the Sensor is being secured with bolts,

observe the allowable tightening torque. Some models require the

use of toothed washers.

For details, refer to the mounting precautions in Precautions for

Correct Use in individual product information.

Mounting/Removing Using DIN Track

(Example for E2CY)

(1)Insert the front of the Sensor into the special Mounting Bracket

(included) or DIN Track.

(2)Press the rear of the Sensor into the special Mounting Bracket or

DIN Track.

•When mounting the side of the Sensor using the special Mounting

Bracket, first secure the Amplifier Unit to the special Mounting

Bracket, and then mount the special Mounting Bracket with M3

screws and flat washers with a diameter of 6 mm maximum.

•While pressing the Amplifier Unit in the direction of (3), lift the fiber

plug in the direction of (4) for easy removal without a screwdriver.

Set Distance

The sensing distance may vary due to fluctuations in temperature and

voltage. When mounting the Sensor, it is recommend that installation

be based on the set distance.

●Wiring Considerations

AND/OR Connections for Proximity Sensors

Note: When AND/OR connections are used with Proximity Sensors, the effects of erroneous pulses or leakage current may prevent use. Verify that there are no

problems before use.

Model Type of

connection Connection Description

DC 2-Wire

AND (series

connection)

Keep the number of connected Sensors (N) within the range of the following

equation.

VS - N × VR ≥ Operating load voltage

It is possible, however, that the indicators may not light correctly and error

pulses (of approximately 1 ms) may be generated because the rated power

supply voltage and current are not supplied to individual Proximity Sensors.

Verify that this is not a problem before operation.

OR (parallel

connection)

Keep the number of connected Sensors (N) within the range of the following

equation.

N × i ≤ Load reset current

Example: When an MY (24-VDC) Relay is used as the load, the maximum

number of Sensors that can be connected is 4.

AC 2-wire

AND (series

connection)

<TL-NY, TL-MY, E2K-@MY@, TL-T@Y>

The above Proximity Sensors cannot be used in a series connection. If need-

ed, connect through relays.

<E2E-X@Y>

For the above Proximity Sensors, the voltage VL that can be applied to the

load when ON is VL = VS - (Output residual voltage × Number of Sensors), for

both 100 VAC and 200 VAC.

The load will not operate unless VL is higher than the load operating voltage.

This must be verified before use.

When using two or more Sensors in series with an AND circuit, the limit is three

Sensors. (Be careful of the VS value in the diagram at left.)

OR (parallel

connection)

In general it is not possible to use two or more Proximity Sensors in parallel

with an OR circuit.

A parallel connection can be used if A and B will not be operated simulta-

neously and there is no need to hold the load. The leakage current, however,

will be n times the value for each Sensor and reset failures will frequently oc-

cur.

("n" is the number of Proximity Sensors.)

If A and B will be operated simultaneously and the load is held, a parallel con-

nection is not possible.

If A and B operate simultaneously and the load is held, the voltages of both A

and B will fall to about 10 V when A turns ON, and the load current will flow

through A causing random operation. When the sensing object approaches B,

the voltage of both terminals of B is too low at 10 V and the switching element

of B will not operate. When A turns OFF again, the voltages of both A and B

rise to the power supply voltage and B is finally able to turn ON.

During this period, there are times when A and B both turn OFF (approximately

10 ms) and the loads are momentarily restored. In cases where the load is to

be held in this way, use a relay as shown in the diagram at left.

Proximity Sensors Technical Guide

Note: When AND/OR connections are used with Proximity Sensors, the effects of erroneous pulses or leakage current may prevent use. Verify that there are no

problems before use.

Extending Cable Length

The cable of a Built-in Amplifier Sensor can be extended to a

maximum length of 200 m with each of the standard cables (excluding

some models).

For Separate Amplifier Sensors (E2C-EDA, E2C, E2J, E2CY), refer

to the specific precautions for individual products.

Bending the Cable

If you need to bend the cable, we recommend a bend radius that is at

least 3 times the outer diameter of the cable (with the exception of

coaxial and shielded cables).

Cable Tensile Strength

In general, do not subject the cable to a tension greater than that

indicated in the following table.

Note: Do not subject a shielded cable or coaxial cable to tension.

Separating High-voltage Lines

Using Metal Conduits

If a power line is to be located near the Proximity Sensor cable, use a

separate metal conduit to prevent malfunction or damage. (Same for

DC models.)

Example of Connection with S3D2 Sensor Controller

Using the S3D2 Sensor Controller

Connecting to a Relay Load

Note: DC 2-Wire Sensors have a residual voltage of 3 V. Check the operating

voltage of the relay before use.

The residual voltage of the E2E-XD-M1J-T is 5 V.

DC 3-wire

AND (series

connection)

Keep the number of connected Sensors (N) within the range of the following

equation.

iL + (N - 1) × i ≤ Upper limit of Proximity Sensor control output

VS - N × VR ≥ Operating load voltage

Note: When an AND circuit is connected, the operation of Proximity Sensor B

causes power to be supplied to Proximity Sensor A, and thus erroneous

pulses (approximately 1 ms) may be generated in A when the power is

turned ON. For this reason, take care when the load has a high

response speed because malfunction may result.

OR (parallel

connection)

For Sensors with a current output, a minimum of three OR connections is pos-

sible. Whether or not four or more connections is possible depends on the

model.

Proximity Sensors Technical Guide

●Operating Environment

Water Resistance

Do not use the Sensor in water, rain, or outdoors.

Ambient Conditions

Do not use the Sensor in the following environments.

Doing so may cause malfunction or failure of the Sensor.

1. To maintain operational reliability and service life, use the Sensor

only within the specified temperature range and do not use it

outdoors.

2. The Sensor has a water resistant structure, however, attaching a

cover to prevent direct contact with water will help improve

reliability and prolong product life.

3. Avoid using the Sensor where there are chemical vapors,

especially strong alkalis or acids (nitric acid, chromic acid, or hot

concentrated sulfuric acid).

●Maintenance and inspection

Periodic Inspection

To ensure long-term stable operation of the Proximity Sensor, inspect

for the following on a regular basis. Conduct these inspections also

for control devices.

1. Shifting, loosening, or deformation of the sensing object and

Proximity Sensor mounting

2. Loosening, bad contact, or wire breakage in the wiring and

connections

3. Adherence or accumulation of metal powder

4. Abnormal operating temperature or ambient conditions

5. Abnormal indicator flashing (on setting indicator types)

Disassembly and Repair

Do not under any circumstances attempt to disassemble or repair the

product.

Quick Failure Check

You can conveniently check for failures by connecting the E39-VA
