802T-HTH

The Allen-Bradley 802T-HTH Electromechanical Limit Switch is a lever-operated industrial limit switch that effectively converts mechanical movement into a discrete electrical signal in a system. This discrete signal will then be normally inputted into an industrial controller such as a programmable logic controller (PLC) in order to inform the system that a certain object or surface in the application process has arrived at the predefined location near the switch. The Allen-Bradley 802T-HTH Electromechanical Limit Switch is capable of operating in both the clockwise and the counterclockwise directions, with maximum torque for contact operation of 0.68 N-m (6 pounds on an inch). Up to 4 independent circuits can be opened and closed at the same time using this limit switch's sensor, which only needs the lever to have a travel 6 degrees in order to change the electrical status of the contacts. This switch is part of the 802T Limit Switches series.

The Allen-Bradley 802T-HTH Electromechanical Limit Switch only comes in a non-plug-in version, where it is completely assembled as one piece with its wiring base. This usually means that the Allen-Bradley 802T-HTH Electromechanical Limit Switch should be wired entirely on the operation side, and that it will take a little more time to repair this switch in the event of a failure than it would to repair a plug-in switch, but it also provides enhanced resistance to harsh industrial atmospheric conditions like the high humidity that is always present on certain kinds of industrial plant floors. The action mechanism of this limit switch is coupled to a spring return system that brings the operating lever back to the neutral point once the force activating the device is no longer present. The maximum allowable travel angle for the switch’s action mechanism is 50 degrees.
