Restrict access to hazardous areas in your workplace with this non-contact safety switch from Schmersal. It works by making one electrical connection and breaking one connection when it senses that the matching magnetic actuator (198-7863) is in position. The coded actuator can't be bypassed using a standard magnet. The device is encased in robust thermoplastic, and it can be discreetly mounted in a concealed position. Use it to switch voltages of up to 100V AC/DC at up to 0.25A.

• IP67 (ingress protection) rating means it's dust-tight and can be submerged for up to 30 minutes
• Operating temperature range of -25°C to +70°C for use in a wide range of environments
• Uses a standard 4-pin M8 connector for simple and fast connection
• Installation is made easier as it's insensitive to transverse misalignment

• Doors and windows
• Machine access panels
• Assembly lines
• Food processing

An M8 connector system uses pre-assembled, over-moulded connectors that simply screw together without the need to solder at the point of installation.
