With the ES/EM 98 Extreme series, steute has developed position switches with metal housings and normed dimensions in acc. with DIN EN 50041, suited to applications in extreme environments. Depending on user preferences and the sealing concept selected, versions are available in protection classes IP 66, IP 67 and IP 69K. A large temperature range from -40 °C to +90 °C further increases the potential of these new Extreme position switches. Users can choose from a large selection of actuators, and available switching inserts include a new contact variant with three contacts designed as a slow action or snap action contact with a positive break NC contact. A certified variant for use in explosive zones is now also available. The switching devices can be used in gas-Ex-zones 1 and 2, as well as dust-Ex-zones 21 and 22.
