Honeywell Sensing and Control EX-AR30 SPDT 1NC/1NO Explosion Proof Limit Switch

The Honeywell Sensing and Control EX-AR30 Explosion Proof Limit Switch is an SPDT part with 1 normally closed and 1 normally open contact, that is used to sense position and offer switching control in HVAC systems in equipment and industrial heating units. It operates by banging internal contacts as a set position or motion is attained, transmitting a signal to the control system. Constructed using an explosion-proof enclosure, it is configured to use in places that may have volatile gases or vapor. This will insure switching action, safe operation and assist in control integrity in severe conditions.
