Ambient Temperature
-25 °C to +85 °C (-13 °F to +185 °F)Description
The LOCA limit switches in this series are metal-encapsulated precision switches in a robust compact construction. The connection is made either by a plug (Harting 7D) or a connection lead with cable gland (SR-SV-M 20, clearance depending on cable). The integrated basic switch is a single-pole changeover contact with a high switching accuracy and precise reproducibility of the switching point.
