Position switch Plastic 50 mm Increased corrosion protection Device connection 2x (M20x 1.5) 1 NO/1 NC slow-action contacts Rounded plunger functional at -40 °C Shock and vibration test according to EN 61373, Category 1B Mechanical position switches SIRIUS 3SE5 for position sensing of machine parts and position monitoring of protection equipment for extreme environmental conditions down to -40 °C, e.g. in wind energy plants, in the food and beverage industry, or for railway applications. Due to their high degree of protection, the devices are suitable for use in extreme environmental conditions. They have increased corrosion protection, have been tested for shock and impact, and are approved worldwide (IEC, UL). With the corresponding switch configuration, the highest safety requirements specified by PL e or SIL 3 can be met. Various enclosure sizes are available in plastic or metal. In addition, versions are available with separate actuator or tumbler. Depending on the design, various operating mechanisms and separate actuators are available. Safety is a SIRIUS business.
