The M1S 660-11-K-Y from Schmersal is a compact position switch specifically designed for industrial applications. The switch complies with EN IEC 60947-5-1 and offers high reliability and long service life.

The position switch features one NC contact and one NO contact. The electrical contacts are made of high-quality, gold-plated silver (AgNi 15 + Au 0.3 µm), ensuring long-lasting and stable switching operations.

With a mechanical lifespan of at least 3 million switching cycles and a snap-action switching mechanism with friction contact, the M1S 660-11-K-Y is particularly durable and suitable for a maximum switching frequency of 30,000 operations per hour.

The switch comes with a 0.5-meter H05VV-F cable, making it easy to install. Additionally, the position switch is certified with an IP65 protection rating and can operate in a temperature range from -30 °C to +80 °C.
