PNP output type available 

## **Miniature-sized and still mountable with M3 screws** 

## **Miniaturization by using single chip optical IC** 

## **Incorporates a sensitivity adjuster even in this size** 

The beam-receiving photodiode and 10.5 mm 8.2 mm The sensor incorporates a sensitivity the A/D conversion circuit have been 0.413 in 0.323 in adjuster in spite of its miniature size. fabricated on a single chip optical IC 19 mm It is convenient when you need fine (full custom). Hence, in spite of its 0.748 in adjustment. Further, the receiver of the miniature size, it has a performance thru-beam, side sensing type sensor and reliability which is equal to or incorporates an operation mode switch better than the conventional product. which can change the output operation. 

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 

## ~~a~~ **BASIC PERFORMANCE** 

## **Long sensing range** 

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. 

## **Thru-beam type** 

## **2 m 6.562 ft** 

**Retroreflective type** 

**200 mm 7.874 in** 

**Diffuse reflective type** 

**160 mm 6.299 in** 

## **Clear beam spot using red LED dot light source** 

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 thru-beam type, too, incorporates a visible narrow beam, it can also reliably detect small parts, such as, chip components, lead frames, etc.

The bars in the graph indicate the sensing range (typical) for the respective material. However, there is a slight variation in the sensing range depending on the product. Further, if there is a reflective object (conveyor, etc.) in the background of the sensing object, since it affects the sensing, separate it by more than twice the sensing range shown in the left graph, or adjust the sensitivity adjuster.

The graph is drawn for the maximum sensitivity setting.

## **Correlation between sensing object size and sensing range** 

As the sensing object size becomes smaller than the standard size (white non-glossy paper 100 × 100 mm 3.937 × 3.937 in), the sensing range shortens, as shown in the left graph.

## **PRECAUTIONS FOR PROPER USE** 

- Never use this product as a sensing device for personnel protection. 

- In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country. 

## **Mounting** 

- Mount using M3 screws. The tightening torque should be 0.5 N·m or less.

## **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.

## **Wiring** 

- Excess bending of the cable or stress applied to the cable may disconnect the internal lead wire. 

## **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-28□** 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. 

L Dark-ON mode is obtained when the operation mode switch D (located on the receiver) is turned fully counterclockwise (D side). 

Note: Operation mode switch should be turned fully till it stops.
