VS2EX Explosion-Proof Shock & Vibration Switch (20700049)

VS2EX: Explosion-Proof Shock & Vibration Switch, Meets IP54 Specs, Class 1, Div 1, Groups C & D (20700049)

The VS2EX Series switches are shock sensitive mechanisms for shutdown of engine or electric motor-powered equipment. These adjustable magnetic shock switches have a wide range and use a magnetic latch to ensure reliable operation.

The VS2EX has a base mounted case, explosion-proof aluminium alloy housing; meets NEMA 7/IP50 specifications; Class I, Division I, Groups C & D; UL and CSA listed with 480 VAC rating. In place of the leaf-type contacts, 2-SPDT snap-switches are used in this model. Sensitivity is externally adjustable and, when tripped, the VS2EX gives a Tattletale indication on the reset button.

Ideal for use on engines, pumps, compressors, heat exchangers and pumping units - the VS2EX can be used anywhere shutdown protection from damaging shock/vibration is desired. Switches are field adjustable to sensitivity required in each application.

There is no calibration report for the VS2EX.

BASIC OPERATION:

Pushing the reset button moves the tripping latch into a magnetically held position. A shock/vibration will move the magnet beyond this holding position, thus freeing the spring-loaded tripping latch to transfer the contacts and shut down the machinery (see dimensional diagrams or visual representation of parts).
