Description
Approach direction
Horizontal and vertical
Can be adjusted in 90° steps
Solenoid operating voltage
- AC/DC 24 V +10%, -15%
Guard locking type
STA3 | Closed-circuit current principle, guard locking by spring force. Release by applying voltage to the guard locking solenoid. |
Switching element
2131 | Slow-action switching contact 2 NC |
+ 1 NO + 1 NC (door monitoring contact)Auxiliary release
This is used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.
Escape release (C1993, long actuator shaft)
