The 803-A6RHW is a rotating cam limit switch, manufactured by Allen-Bradley, and is a variation of the cam limit switches of the 803 series. This unit comes with extra characteristics that were added to one of the base units from style “A” in order to comply with and fulfill industrial requirements and needs. The 803-A6RHW rotative cam limit switch has a shaft speed of 150 RPM (Revolutions Per Minute) and each cam operates at a range of 25 Amps. This cam limit switch contains 6 cams or circuits and a standard right-hand shaft extension, which can be chosen by the user, depending on the requirements of the machine or process. The 803-A6RHW rotating cam limit switch contains a mechanism that enables it to change the relative position between the driving mechanism and the shaft. This is done by means of a sprocket, which works as an external adjustment. The cam duration is a minimum of 14 degrees and a maximum of 346 degrees and with this mechanism, while the device is stopped and by pulling out the knurled to disengage the spline, the cam’s shaft can be incremented by 5 degrees.

The length of the 803-A6RHW rotating cam limit switch is around 8.31 inches (211.1 millimeters); its approximate shipping weight is 31 pounds (14.1 kilograms). It has anti-vibration mechanism, conduit entrances on each side, and rugged cast iron side plates. The 803-A6RHW rotating cam limit switch features a type 1 NEMA enclosure, enabling it to be used in an indoor environment only. In addition, it possesses internal dwell and timing adjustments, while this module’s base is made of heavy-duty steel.
