Bernstein Werkzeugfabrik Limit Switch GC-SU1 FF

The Bernstein Werkzeugfabrik GC-SU1 FF is a high-quality limit switch designed for industrial automation and safety applications. Featuring a roller plunger actuator and snap-action switching mechanism, this switch ensures reliable and precise position detection. With a robust thermoplastic housing (glass-fibre reinforced) and IP65 protection, it is suitable for harsh environments. The switch offers 1 normally open (NO) and 1 normally closed (NC) contact configuration with positive break operation, meeting stringent safety standards.

Advantages

Durable construction with glass-fibre reinforced thermoplastic housing ensures long service life. IP65 rating provides protection against dust and water jets. Positive break operation guarantees safe switching even in the event of welded contacts. High mechanical life of over 10 million operations reduces maintenance costs. Wide operating temperature range from -30 °C to +80 °C allows use in extreme conditions.
