Prevent guards or gates from opening when hazardous operations are underway with this safety interlock switch from Schmersal. It unlocks only when the internal solenoid is opened and all machinery has stopped operating to enhance safety in industrial environments. The switch has an aluminium housing for resistance to impact and corrosion for use in harsh conditions. The contacts are made of silver for high levels of conductivity and resistance to corrosion, ensuring a reliable and long-lasting connection.

• Broad operating temperature range of -30°C to +90°C for use in a variety of demanding environments
• IP67 (ingress protection) rating indicates the connector is dust-tight and protected against immersion in up to 1m of water for 30 minutes
• Secure screw connection holds the unit in place even in the event of heavy shocks and vibration
• Compact dimensions of 114 (length) x 40.5 (width) x 38mm (depth) for installation in areas where space is limited
