notice
 
Contact symbols shown for the closed condition of the guard device.
The contact configuration for versions with or without LED is identical.
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
Contact S21-S22 must be integrated in the safety circuit
 
Included in delivery
 
Actuators must be ordered separately.
