Wet, extreme temperatures and explosive zones: these are typical environments for the completely new ES/EM 98 standard position switch series from steute, which we shall be presenting at the Hanover fair.
Mounting dimensions in accordance with DIN EN 50041, our new position switches are very versatile. Their robust metal enclosures can withstand high levels of mechanical wear and tear. Depending on the wishes of the user and the sealing type, variants in protection classes IP 66, IP 67 and IP 69K are available. An enormous temperature range from -40°C to +90 °C increases the application potential for this new switchgear series even further.
Users can choose from a large selection of actuators, and the available switching inserts include a new, pressure-resistant variant with three contacts designed as a snap action contact with positive break NC contact. In the near future variants will also be available which have been reinforced to meet the requirements for gas and dust explosion protection (zones 1 and 2/ zones 21 and 22 according to ATEX guidelines) and correspondingly certified.
As a further, particularly innovative addition to the new range, steute has developed RF 98 wireless versions which work according to the »energy harvesting« principle and require neither cables not batteries. With these features the new series is suited to all manner of tasks in the automation industry – including and especially in areas with extreme ambient conditions.
