Structure and function
Overview
The L25 single-beam photoelectric safety switch is an electro-sensitive protective
device consisting of a sender and receiver.
The hazardous area is protected by means of a light beam between the sender and
receiver. As soon as the light beam is interrupted, the protective device reports the
interruption in the light path to the secure output signal switching devices.
Sensing range
The scanning range is the maximum dimension of the light path between sender and
receiver. This depends on the light source of the sensor.
