Keep hazardous areas out of bounds with this non-contact safety switch from Schmersal. The device will break two electrical connections when it senses that the matching magnetic actuator is in position and the power to a machine needs to be cut. To prevent tampering, the actuator is coded so it can't be bypassed using a standard magnet. The switch has an ON distance of 5 to 8mm and an OFF distance of 15 to 18mm. It works with voltages of up to 60V AC/DC at up to 0.25A. You can buy the matching actuator (198-7863) separately.

• Operating temperature range of -25°C to +70°C for use in a wide range of industrial environments
• 4-pin M8 connector makes for simple and fast connection
• Glass fibre-reinforced thermoplastic enclosure is tamper-resistant and self-extinguishes if subjected to fire

• Security systems
• Machine access panels
• Assembly lines
• Food processing industry

These switches are robust and not negatively affected by heavy vibration. They're particularly suited to applications where door misalignment is common and where hygienic conditions don't need to be maintained.
