PNP output type available 

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

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

The beam-receiving photodiode and 10.5 mm 8.2 mm the A/D conversion circuit have been 0.413 in 0.323 in fabricated on a single chip optical IC 19 mm (full custom). Hence, in spite of its 0.748 in miniature size, it has a performance and reliability which is equal to or better than the conventional product. 

## **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. 

## **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.

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

**==> picture [230 x 222] intentionally omitted <==**

**----- Start of picture text -----**<br>
The emission area of a dot light source is smaller than that<br>of a conventional LED flat light source, and it is possible to<br>design a high power, narrow beam. Since a red LED dot<br>light source is used, the red beam spot is clear even at a far<br>place, so that alignment and confirmation of sensing position<br>is easy. Further, since the thru-beam type, too, incorporates<br>a visible narrow beam, it can also reliably detect small parts,<br>such as, chip components, lead frames, etc.<br>EX-28□<br>e e<br>Setting<br>distance:<br>80 mm<br>ø5 mm<br>EX-26□ ø0.197 in 3.150 in<br>spot<br>ø1 mmø0.039 in Setting<br>spot distance:<br>10 mm<br>0.394 in<br>**----- End of picture text -----**<br>

NOTE: Mounting bracket is not supplied with the sensor. Please select from the range of optional sensor mounting brackets (four types) or universal sensor mounting bracket. (Refer to p.331) 

- Notes: 1) The sensing range of the retroreflective type sensor is specified for the **RF-200** reflector. Further, the sensing range is the possible setting range for the reflector. 

200 mm Reflector cannot Actual sensing range 7.874 in be placed of the sensor in this range 30 mm 1.181 in Setting range of the reflector 

- The sensor can detect an object less than 30 mm 1.181 in away. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque. 

- 2) In case of using this product at a sensing range of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. 

- 3) The model No. with “ **P** ” shown on the label affixed to the thru-beam type sensor is the emitter, 

- “ **D** ” shown on the label is the receiver.

- 4)  The sensing range and the sensing object of the retroreflective type sensor are specified for the **RF-200** reflector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 30 mm 1.181 in away. However, if the reflector is set  1.181 in away. However, if the reflector is set   away. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque. 

- 5) In case of using this product at a sensing range of 50 mm 1.969 in or less, take care that the sensitivity adjustment range becomes extremely narrow. 

- 6) Make sure to confirm detection with an actual sensor before use.

Narrow-view reflective type 

## **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.

Note: When mounting the front sensing type sensor, use M3 pan head screws without washers, etc. 

- When mounting the front sensing type from the backside, fit the mounting spacer ( **MS-EX20-FS** ) and fix with screws. 

## **Mounting method** 

- 1   Fit the mounting 2 Align the mounting holes of spacer on the sensor. the mounting spacer and the Mounting sensor and mount with M3 spacer (Optional) screws. The tightening torque should be 0.5 N·m or less. M3 screws

## **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.
