SICK RE31 Series Safety Switch, 36mm Length, Fibreglass Reinforced PPS Housing - RE31-DAC

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.

Features and Benefits:

• 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

Applications

• 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

What type of housing material does it use?

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

How are faults in the switch detected?

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

What are the electrical switching limits?

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

Which connection format is provided for wiring?

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

How robust is the unit against vibration and shock?

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