SICK RE31 Safety Switch, RFID Actuator Included, Fibreglass Reinforced Polyphenylene Sulphide, Magnet

This safety switch is a non-contact magnetic interlock designed to monitor access points in industrial settings. It operates with a paired actuator and provides both normally open and normally closed safety contacts for integration with safety logic. The device is rated for outdoor and harsh environments and connects via a 4-pin M8 plug. It is suitable where compact, sealed switching and straightforward actuator pairing are required.

• IP67 enclosure rating provides protection for washdown environments
• Reed contact outputs support low-voltage switching up to 30V DC
• 1NO and 1NC safety contacts enable dual-circuit monitoring
• Actuation possible from five directions for flexible installation
• Operating range supports environments from -20°C to +60°C

• Used for guarding doors on conveyor lines
• Suitable for machine access monitoring in manufacturing
• Ideal for pairing with safety logic units for diagnostics
• Can be used with Compact actuators in confined spaces
• Used for installations requiring plug-in M8 connectivity

The housing is MADE from glass-fibre reinforced polyphenylene sulphide to resist mechanical and environmental stress.

The unit lacks internal fault detection so the connected safety-related logic unit must perform fault monitoring.

Switching current is limited to 400mA and switching voltage to ≤30V DC with reed contact outputs.

A 4-pin M8 plug connector is used for electrical connection.

It meets vibration resistance at 10Hz to 55Hz with 1mm amplitude and shock resistance of 30g for 11 ms.
