Type 83 894 1 safety switches are fitted with an electromagnet for locking/unlocking the guard.
With the guard locked, the force required to remove the key is
200 daN.
In addition to the 3
-pole contact element actuated by the key, 83 894 2 limit switches also have a positive break type
"NC + NO" contact
element,
actuated by the electromagnet.
The "NC" contact is integrated in the machine safety circuit, and the "NO" contact indicates the position of the electromagnet.

Type 83 894 1 safety switches are supplied with a key-operated lock which can be used to unlock the moving guard, bypassing the electromagnet.
Unlocking using a key
-operated lock is recommended in the following cases :
machine maintenance (if the key is turned to "UNLOCK" and then removed, this will prevent the machine from restarting accidentally, therefore ensuring the safety of maintenance personnel).
mains failure
problem with unlocking (locking cannot be released : fail-safe condition). Unlocking by applying voltage to the electromagnet always takes priority over unlocking using a key-operated lock.
The locking mechanism for standard devices allows the key to be removed in the "LOCK" and "UNLOCK" positions.
Power supply for the electromagnet on 83 894 1
The electromagnet for type 83 894 1 safety switches runs on D.C. and is therefore particularly reliable.
As it is protected by a bridge rectifier A.C. or D.C. supplies can be used (24 V, 48 V, 120 V or 230 V).
