Probe Pin XP3A 1
Probe Pin
XP3A
Electroplated Probe Pin for High
Reliability
• The Probe Pin is made of only one part.
• The flat structure helps you reduce the pin pitch in comparison
with standard probe pins.
• Separating the spring and relay achieves a stable resistance
and greater durability.
Features
■
Achieves the functions of four parts with one part
■Separating the spring and relay achieves a
stable resistance and greater durability
■
The electroformed Probe Pins use a flat structure.
This allows you to position the pins at any angle.
In comparison with round pins, these flat Probe Pins help you reduce
the pin pitch
■Socket
■Ratings and Characteristics
Note: The performance values are doubled for two pins.

Precautions
■Correct Use
General Environmental Conditions
Use the Probe Pins at an ambient operating temperature of
-25 to 85°C and a humidity of 30%.
Use the Probe Pins in an ambient atmosphere that does not contain
dust, dirt, corrosive gas or oil so that the Probe Pins do not become
contaminated.
Stroke Conditions
Apply a load to the Probe Pins only in the axial direction.
Never apply a lateral load.
The life of the Probe Pins will be drastically reduced if the
recommended stroke is exceeded.
Current Application Conditions.
Apply a current when the Probe Pins are stationary after they have
come into contact with the target at the recommended stroke posi-
tion.
If a current is applied during the stroke, at a position other then the
recommended stroke, or when the Probe Pins are not in contact with
the target, the life of the Probe Pins will be drastically reduced.
The catalog value of the carrying capacity may not be met due to
Probe Pin deterioration or other factors. Allow sufficient leeway when
you design the actual application.
Voltage Application Conditions
Apply a voltage when the Probe Pins are stationary after they have
come into contact with the target at the recommended stroke posi-
tion.
Do not apply a voltage when the Probe Pins are not in contact with
the target. The Probe Pins will be damaged due to discharge imme-
diately before they come into contact.
When a high voltage is applied to the contact probe, strictly observe
the current and voltage application conditions. Also, take measures
to prevent discharge or other large instantaneous current.
Carrying Capacity
The rated current that is given in the catalogs is the maximum contin-
uous current for 1 minute under the above conditions (general envi-
ronment, stroke, current application and voltage application.
Resistance
If a large current is applied, the resistance may increase due to dete-
rioration of the contacts and internal components.
As the number of strokes increases, the resistance may increase due
to deterioration of the contacts and internal components.
Durability
The durability specification that is given in the catalog is a guideline
for the number of times that the Probe Pins can be used without
problems at 10 mA.
Depending on the operating environment and conditions, the Probe
Pins may need to be replaced sooner than given in the specifications
due to increased resistance, reduced contact force or other factors.
Replace the Probe Pins as required by the actual application.
Contact Force
The contact force of the Probe Pins will be reduced at a temperature
of 85°C or higher.
If the current is increased, heat generated by the Probe Pins will
reduce the contact force.
Recommended Mounting Hold Dimensions
The dimensions are reference values. Actual values will depend on
the material and thickness of the resin plate.
