Ultra-compact Photoelectric Sensor Amplifier Built-in PNP output Light intensity type available monitor CX-400 PHOTOELECTRIC SENSORS EX-20 SERIES Conforming to EMC Directive EX-40 RX RX-LS200 UL Recognition (Excluding 5 m cable length type) Miniaturization by using single chip optical IC Long sensing range Clear beam spot using red LED dot light source The beam-receiving photodiode and the A/D conversion circuit have been fabricated on a single chip optical IC (full custom). Hence, in spite of its miniature size, it has a performance and reliability which is equal to or better than the conventional product. The EX-20 series achieves long distance sensing [thru-beam type: 2 m 6.562 ft, retroreflective type: 200 mm 7.874 in (when using the attached reflector), diffuse reflective type: 160 mm 6.299 in], despite its miniature size. Hence, it is usable even on a wide conveyor. The emission area of a dot light source is smaller than that of a conventional LED flat light source, and it is possible to design a high power, narrow beam. Since a red LED dot light source is used, the red beam spot is clear even at a far place, so that alignment and confirmation of sensing position is easy. Further, since the thrubeam type, too, incorporates a visible narrow beam, it can also reliably detect small parts, such as, chip components, lead frames, etc. EQ-30 EQ-20 Amplifier Built-in EX-10 EX-20 EX-30 Miniature-sized and still mountable with M3 screws 10.5 mm 0.413 in 8.2 mm 0.323 in 19 mm 0.748 in Thru-beam type 2 m 6.562 ft EX-28 Incorporates a sensitivity adjuster even in this size The sensor incorporates a sensitivity adjuster in spite of its miniature size. It is convenient when you need fine adjustment. Further, the receiver of the thru-beam, side sensing type sensor incorporates an operation mode switch which can change the output operation.

The sensor can be hosed down because of its IP67 construction. Further, the sensor mounting bracket is also made of stainless steel. PNP output type, which is much in demand in Europe, is also available. Of course, it conforms to the EMC Directive and approved UL Recognition (excluding 5 m 16.404 ft cable length type). Note: However, take care that if it is exposed to water splashes during operation, it may detect a water drop itself. 218 Ramco Innovations - 1207 Maple Street, West Des Moines IA USA 50265 - 800-280-6933 - www.ramcoinnovations.com APPLICATIONS Checking protrusion of wafer Sensing objects from an opening Two types for suitable mounting Identical size Universal sensor mounting bracket is available Two types, side sensing type and front sensing type sensors are available.

This product is not a safety sensor. 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 * Mount using M3 screws. The tightening torque should be 0.5 N m or less. Front sensing Side sensing Stability indicator * The stability indicator (green) lights up when the incident light intensity has sufficient margin with respect to the operation level. If the incident light intensity level is such that the stability indicator lights up, stable sensing can be done without the light received operation and the light interrupted operation being affected by a change in ambient temperature or supply voltage.

Reflector Glossy surface Sensing object 10 to 30 M3 screws Step Sensitivity adjuster Description Sensor MAX Turn the sensitivity adjuster fully counterclockwise to the minimum sensitivity position (* mark). 1 MAX 2 A B MAX 3 Optimum position In the dark condition, turn the sensitivity adjuster further clockwise until the sensor enters the `Light' state operation and then bring it back to confirm point b where the sensor just returns to the `Dark' state operation. If the sensor does not enter the `Light' state operation even when the sensitivity adjuster is turned fully clockwise, this extreme position is point b. B ) MAX The position at the middle of points is the optimum sensing position. @ and b L Make L sufficiently long Wiring * Make sure that the power supply is off while wiring. * Verify that the supply voltage variation is within the rating. * If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. * In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. * Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. * This can cause malfunction due to induction. A Notes: 1) Use the attached adjusting screwdriver to turn the adjuster slowly. Turning with excessive strength will damage the adjuster. Notes: 2) In case of using EX-22 at a sensing distance of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. Operation mode switch (EX-23 only) Switch position L D L D Description Light-ON mode is obtained when the operation mode switch (located on the receiver) is turned fully clockwise (L side). Dark-ON mode is obtained when the operation mode switch (located on the receiver) is turned fully counterclockwise (D side). Others * Do not use during the initial transient time (50 ms) after the power supply is switched on. * If sensors are mounted close together and the ambient temperature is near the maximum rated value, provide for enough heat radiation / ventilation. * If a reflective object is present in the background, the sensing of EX-28A(-PN) and EX-28B(-PN) may be affected. When setting the sensor, make sure to confirm that the reflective object has no effect. In case the reflective object affects the sensing, take measures such as removing the reflective object or coloring it in black, etc. Note: Operation mode switch should be turned fully till it stops.
