BOS R254K-…-LH10/LH11/LH12-…
In the case of a diffuse sensor with adjustable background
suppression, the emitted light is reflected by the object and
evaluated in the receiver. The background suppression
allows recognition in the detection range that is almost
object-independent.
BOS R254K-…-LK10-…
In the case of a retroreflective sensor, the emitted light is
reflected back to the sensor by a reflector. Interruption of
the light beam by an object causes the switching
operation.
BOS R254K-…-LE10/LS10-…
Through-beam sensors are sensors having separate
transmitter and receiver units which must be aligned with
each other on opposite ends of the detection range. When
an object interrupts the light beam, the receiver switches,
i.e. the output signal changes.
