Coding types
The sensors are available in various coding types. When combined with the coded actuator,
this results in a corresponding encoding level for the safety switch according to
EN ISO 14119.
Fixed, unique assignment
Fixcode:
For the sensor to detect the actuator, the actuator must first be assigned to the sensor by
means of a learning process.
See Section “Startup” on page 38.
The learning process can be carried out once. The sensor and actuator are then perma-
nently assigned to each other by their coding.
Safety switches with fixcode evaluation achieve a
high
encoding level.
Fixed, multiple assign-
ment
Unicode:
For the sensor to detect the actuator, the actuator must first be assigned to the sensor by
means of a learning process.
See Section “Startup” on page 38.
Teaching-in of a new actuator can be repeated any number of times. The sensor only
detects the last taught-in actuator.
Safety switches with unicode evaluation achieve a
high
encoding level.
No fixed assignment
Multicode:
The sensor detects every actuator of the permssible type. No specific actuator code can be
assigned.
It is not necessary to teach in an actuator.
Safety switches with multicode evaluation achieve a
low
encoding level.
Overview of sensor coding types
You can use the product designation to determine the coding type of the sensor, which is
the letter after PSR-CT-...
