RX-LS200 Amplifier Built-in Adjustable Range & Fixed-focus Reflective Photoelectric Sensor Detection of Different Color Objects at a Certain Distance Marked 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. Principle of Optical Sensing 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. RX-LS200 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. Receiving lens The sensing range can be changed according to the position of the lens. Sensing object ) Sensing object 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. Emitting LED Background (specular) Emitting lens Receiving element (Photo-diode) Insusceptible to Dust 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. 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. Receiving element (Photo-diode) Dust 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.

Its use is not intended or designed to protect life and prevent body injury or property damage from dangerous parts of machinery. It is a normal object detection sensor. Mounting * The tightening torque should be 1.17Nm or less. 5.5mm M4 (length 16mm) hexagon-socket-head bolt MS-RX-1 (Accessory) 6mm Beam axis The sensing axis is positioned at the intersection of the ` ' mark on the lens face and the `I' line. * Care must be taken regarding the sensor mounting direction with respect to the object's direction of movement. * When detecting a specular object (aluminum or copper foil) or an object having a glossy surface or coating, please take care that there are cases when the object may not be detected due to a small change in angle, wrinkles on the object surface, etc. * When a specular body is present below the sensor, use the sensor by tilting it slightly upwards to avoid wrong operation. * If a specular body is present in the background, wrong operation may be caused due to a small change in the angle of the background body. 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. 196 03/2003 RX-LS200 PRECAUTIONS FOR PROPER USE Distance adjustment <Adjusting procedure> <Adjusters> Pointer ( Step Distance adjuster (2-turn) It shows how much the distance adjuster is rotated. ) sensing range increases as it is ( The ) turned clockwise.
