Retroreflective area sensor

with 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

one housing and with a reflector positioned
opposite forms a 60 mm detection area over
a sensing 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.

intelligent 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.

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
