Position Switch PS-3

MODEL PS-3 POSITION SWITCH

The Model PS-3 Position Switch is utilized to monitor the position of heavy moving machinery such as a gravity take-up or a tripper car. Once the roller actuator arm is moved from its normal position the two (2) micro switches are tripped. The micro switches can be used to send an alarm to the controls system or operator telling it or them to either shut off or move the piece of heavy machinery.

The PS-3 Position Switch is commonly found on tripper floors to annunciate the position of the tripper car ensuring that the material is being unloaded in the correct spot. They are also utilized as a limit switch to protect gravity take-ups on conventional conveyors from bottoming out.

The PS-3 Position Switch is essentially a heavy duty limit switch and has a variety of uses in industrial environments. It assures safe operation and automation of the equipment in your plant.
