This Rotating Cam Limit switch, the 803-A44RH, belongs to the 803 family, manufactured by Allen-Bradley. It is a pilot device used for rotary tables, waterway gates, lock operations, presses, and packaging machines, as well as in other applications in which there is a need for a sequential position feedback and control. When through a gear train, roller chain, or directly, the movement is achieved on the rotating cam limit switch and this device can open and close the control circuits. The user will mechanically set angular positions at which actuation is performed. Its rotation can be either clockwise or counter-clockwise and any plane can be used for installation purposes. The 803-A44RH has a housing shaped with style A nomenclature. Its number of separate switching circuits (with independent cam operators) is four. The switching capacity for these normally closed double break contacts is 25A. The 803-A44RH limit switch is equipped with a 4 & 13 industrial enclosure, tightly encapsulated against the intrusion of water, dust, and oil. When observed from the face side of this device, its shaft is located on the standard left side.

The 803-A44RH limit switch body includes a number of features such as a shaft with oversized ball bearings, a steel base (heavy duty), cam segments with adjustable dwell and timing, rugged cast iron sides, cable glands on each side, and control contacts that are normally closed and cam opened. The Allen-Bradley 803-A44RH has shipping weight around 39 pounds (17.7 kilograms) and its dimensions are 274.6 x 301.6 x 173.0 millimeters (10.81 x 11.88 x 6.81 inches). Its ideal operating temperature zone is -22 to 150 degrees Fahrenheit (-30 to 66 degrees Celsius). Manufacturing of this model was terminated in 2007.
