DA420 Request to exit proximity switch
Availability: 48 in stock
Activated through close proximity, these request to exit (RTE) switches control a single-pole change-over (SPCO) relay with normally-closed or normally open contacts. Uses include signalling or switching of automatic doors, locks or any electronic equipment using the SPCO clean relay contacts. Simply hold something, such as your hand near the switch and it will operate. Ideal for use in
clean rooms where minimum or no contact with objects is required to reduce the risk of cross-contamination for hygiene.
