Safelock is a safety switch utilised in the protection of personnel when opening doors leading to dangerous areas.
It acts by monitoring and interrupting the safety circuit during dangerous scenarios. The solenoid locks and unlocks access to the dangerous area, guaranteeing safety until the danger has stopped.

Available models:
SLK-M
• Retention mechanism actuated by a spring and unlocked by ON current.
• Guard locking by spring force, release by applying voltage to the guard locking solenold

SLK-E
• Retention mechanism actuated by ON current and unlocked by spring.
• Guard locking by applying voltage to the guard locking solenoid, release by spring force
