Suitable for

• Monitoring the position of machine parts
• Safety monitoring of protective equipment and gates
• Industrial automation systems requiring precise mechanical detection
• Applications compliant with EN 50047 standards

When it may not be suitable

This switch may not be appropriate for environments involving extreme chemical exposure or high-impact mechanical forces that exceed the specifications of the plastic enclosure. It is also not intended for use in explosive atmospheres unless specifically rated for such conditions.

Key specifications

• Enclosure material: Plastic
• Actuator type: Roller plunger with 10 mm plastic roller
• Contact configuration: 1 NO / 2 NC quick-action contacts
• Connection type: 1 x M20 x 1.5
• Standard compliance: EN 50047
• Width: 31 mm

How to use

The switch should be mounted in a location where the moving machine part can reliably actuate the roller plunger. Ensure the mounting surface is stable and aligned with the movement path of the equipment. Connect the device using the M20 x 1.5 cable entry, following the wiring diagram for the 1 NO/2 NC contact configuration. Once installed, verify that the actuator is triggered correctly by the machine movement and that the electrical signal is received by the control system.

What to consider before purchase

• Verify that the 31 mm enclosure size fits your mounting space
• Ensure the roller plunger actuator is compatible with the mechanical movement of your equipment
• Check that the 1 NO/2 NC contact configuration meets your control system requirements
• Confirm that the M20 x 1.5 connection matches your existing cabling infrastructure

Usage recommendations

Regularly inspect the roller plunger for signs of mechanical wear and ensure the enclosure remains free of debris to maintain consistent switching performance. Periodically test the safety function to confirm that the switch continues to meet the required safety integrity levels for your specific application.
