Protect your industrial equipment and personnel from accidents using this solenoid interlock switch from Schmersal. It keeps the guard element of the machine locked while it's in operation to prevent contact that may injure the operator or damage your equipment. For added safety in the event of a fire, its durable glass fibre-reinforced thermoplastic body is self-extinguishing. A long mechanical service life of more than 1,000,000 operations means you can rely on it for long-term use. Thanks to its broad operating temperature range between -25°C and +60°C, this unit can withstand use in harsh environments.

• Latching force of 30N for a secure hold
• IP67 rating means it's protected against dust and immersion in 1m of water for up to 30 minutes
• Fast actuation speed of 2m/s for a rapid response

• Security systems
• Construction industry
• Packaging industry
• Medical technology

A power-to-unlock interlock switch will remain locked even when the machine is no longer active and requires a separate actuation to unlock it. This helps to improve safety in areas where hazards persist even when a machine is disconnected.
