Açıklama
Solenoid operating voltage
- AC/DC 24 V +10%, -15%
Guard locking type
STA4 | Open-circuit current principle, guard locking by applying voltage to the guard locking solenoid. Release by spring force. |
Switching element
4121 | Slow-action switching contact 2 NC |
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.
