Amplifier Built-in Adjustable Range & Fixed-focus Reflective Photoelectric Sensor EQ-20 PHOTOELECTRIC SENSORS RX-LS200 EX-40 EQ-30 Detection of Different Color Objects at a Certain Distance Conforming to EMC Directive Not Affected by Color Waterproof The color or size of the object does not affect its sensing. The sensor can be hosed down because of its IP67 construction. The equipment on which the sensor is mounted can be washed without any problem. EX Adjustable Range & Fixed-focus Reflective Type The sensing range for which the sensor detects an object is determined by the incident beam angle, regardless of the incident light intensity. Receiving element (2-segment device) ( Note: However, take care that if it is exposed to water splashes during operation, it may detect a water drop itself. Not Affected by Background Robust The sensor does not detect the background beyond the set distance since it is distance settable type. Its robust enclosure is made of diecast zinc alloy. PX-2 Background (specular) RT-610 Principle of Optical Sensing RX-LS200 CY RX-LS200 RX Amplifier Built-in Type Marked High-speed Response Time: 1ms The sensing performance is less affected by dust as it does not depend on the incident light intensity. It can be used on a high speed assembly line. Dust ) Sensing object Emitting LED Emitting lens Sensing range Convergent Reflective Type The sensor detects an object only in the overlapping area of the emitting and receiving envelopes. The detectability is a little influenced by the reflectivity of the object surface. Receiving element (Photo-diode) Insusceptible to Dust Receiving lens The sensing range can be changed according to the position of the lens. Sensing object Emitting LED Receiving lens Sensing area Emitting lens Sensing range Diffuse Reflective Type The sensing range changes with the reflectivity and size of the sensing object.

In that case, install the sensor at an inclination and confirm the operation with the actual sensing object. * Do not install the sensor at a distance of less than 50mm from the object because the sensing is unstable in this range. Wiring * The output of RX-LS200-P is not incorporated with a short-circuit protection circuit. Do not connect it directly to a power supply or a capacitive load. Others * Do not use during the initial transient time (50ms) after the power supply is switched on. Sensing object Sensing object Sensing object Do not make the sensor detect an object in this direction because it may cause unstable operation. 270 PRECAUTIONS FOR PROPER USE Refer to P.820l for general precautions.
