## **Model Number** 

## **RLG28-55/40a/115b/136** 

## Retroreflective area sensor 

with 300 mm fixed cable and 4-pin, M12 x 1 connector 

## **Features** 

- Retro-reflective area sensor with 6 light beams in standard photoelectricsensor enclosure 

- Connection compatibly replaces single beam photoelectric sensor 

- Reliable detection of the front edge of the object irrespective of its shape and position 

- Constant object detection from 12 mm within the entire detection area 

- Reliable detection of all surfaces irrespective of the object texture 

- Switches when contrast difference 10% 

- Bright, highly visible transmitter beams, guarantee convenient alignment of the sensor 

## **Product information** 

- The RLG28 retro-reflective area sensor con- 

tains several transmitters and receivers in one 

- housing and with a reflector positioned oppo- 

- site forms a 60 mm detection area over a sen- 

- sing range of 4 m. 

- When the light beams are interrupted by an 

- object, the switching function is triggered. The smallest detectable object size is 12 mm. The RLG28 switches at a 10% contrast diffe- 

- rence with a response time of 1 ms. An intelli- 

- gent gain control compensates for effects such as dirt, misalignment, and temperature.

**Notes** 

## **Mounting:** 

Ensure that the red light transmitted by the sensor fully illuminates the reflector. To ensure optimal detection, the entire 60 mm detection field must appear on the reflector.

More stringent adjustment requirements: Ensure that the device is correctly aligned in the near range of 0.2 m ... 0.6 m. 

## **Object detection after successful Teach-in** 

The target should be large enough so that the reflector is always completely covered in one dimension!

## **Signal tracking:** 

Active: 

- At variable temperature 

- Objects located in the light path that lie below the switching point. These objects result in a readjustment of the emitter. This allows these objects to be taught in or taught out. 

Inactive: 

- Function not available 

To alter the signal tracking, press the Teach-in button for >10 seconds. The current status is displayed. Briefly pressing the Teach-in button changes the mode.
