Design with snap-action contact element and positive break contact
All contact bridges have a double break and are galvanically isolated from each other
One N/C and one N/O
N/C contacts are positive break contacts in accordance with IEC 204 / DIN VDE 0113 and fulfil the requirements of DIN VDE 0660 Part 206 (security feature)

This limit switch from Schmersal helps improve the overall safety of your control system. Its proximity-sensing ability means it can detect the presence or absence of an object and accordingly make or break an electrical connection. The unit's adjustable actuator head lets you choose the angle that best suits your needs. Silver contacts provide excellent resistance to electrical arcing and contact welding, making this a reliable choice with little risk of component failure. Switches of this kind are commonly used in lifts, escalators and injection-moulding machinery.

• User-friendly screw-in terminal points
• IP (ingress protection) rating of 67 means it's dust-tight and water-resistant
• Strong thermoplastic housing for protection against moisture and chemicals
• Galvanically isolated contact elements make it possible to switch voltages with different potential
• Meets IEC/EN 60947-5-1 (International Electrotechnical Commission / European Norm) safety standards for low voltage switchgear and control gear

• Printing industry
• Special parts manufacturing
• Lifts and escalators

The speed of travel of a snap-action contact is not controlled by the operational speed of a switch's actuator. Instead, a spring mechanism operates the contact once a certain tension has been achieved. This results in fast and reliable contact operation.
