The 803-A11RH is a rotating cam limit switch manufactured by Allen Bradley. This model presents itself as a variation of the model 803-A11 from the 803 series, with the main difference being the non-standard right-hand extension. This switch comes handy for a number of particular industrial applications that require a cam switch with extended length shafts, with the standard shaft on the left side of the module, and the extension shaft on the right side. This extended right-hand side shaft is a unique feature of the 803-A11-RH module, not being found on the original, 803-A11. The approximate length of the Allen Bradley 803-A11RH rotating cam limit switch is 16.19 inches (411.2 millimeters), and the approximate shipping weight is 44 pounds (18.1 kilograms). This unit is manufactured on a durable heavy material, and each cam has a mechanism that makes it anti-vibration and anti-shock.

The Allen Bradley 803-A11RH switch operates at a temperature that goes from -22 to 150 degrees Fahrenheit. Each cam operates at 25 Amperes and 150 RPM. This unit also counts with 11 independent cam operators, with each operator having a minimum duration of approximately 15 degrees and a maximum duration of around 360 degrees. This unit usually operates at a wide temperature range, taking into account that when it operates below 32 degrees Fahrenheit (0 degrees Celsius) in the presence of water or other liquids, the controls may not work at their full range due to the freezing of liquids at that temperature. This module is protected mainly by a Type 1 enclosure; this enclosure sops particles and dust from entering into the module, but it does limit the use of the switch to Indoor usage only. The main function of the Allen-Bradley 803-A11RH rotating cam limit switch is to precisely control the limits of rotary motion expressed in shaft rotation. It is used in a wide range of industrial applications such as stamping machines, forging presses, and sheet metal forming machines, among others.
