Functions and features
The colour sensor detects coloured objects and materials without contact in diffuse-
reflection or retro-reflective mode.
Mounting
Mount the colour sensor in such a way that the object to be detected makes as lit-
tle lateral and vertical movement as possible. Consider the specified sensing range.
Transparent objects can be better detected by means of a suitable reflector. Mount
the reflector opposite the colour sensor so that the light beam strikes the centre of
the reflector.
In the case of moving objects the direction of movement should be transverse to the
sensor to achieve optimum repeatability (this only applies to sensors with a sensing
range of 12.5 mm).
In the case of shiny object surfaces the sensor should be mounted at an angle of in-
clination of 10 ... 30° referred to the object.
Electrical connection
Disconnect power and connect the sensor as indicated on the type label.
The input AT (activation trigger = synchronising signal) can be used for triggering the
sensor via an external voltage signal.
Sensor deactivated:
12 V < AT < U

The input ET (External Teach) can be used for programming the reference colour for
the output out1 via an external voltage signal.
