Description

Guard Locking Principle

Closed-circuit current (power to unlock): In a safety guard with guard locking according to the closed-circuit current principle, the guard is locked by spring force until the guard locking solenoid is supplied with current. The guard is unlocked by means of magnetic force. This is also referred to as mechanical guard locking.

Switching Element

4131	Slow-action switching contact
	Contacts for guard locking: 2 positively driven, positively driven contacts, 2 NO contacts
