This unit qualifies as a style “B” modified “internal adjustments” cam. The mechanical structure of the Allen-Bradley 803-B3RH rotation cam limit switch includes multiple circuits with a snap action contact block assembly, a spring-loaded cam roller assembly mounted to a heavy-duty steel base, and 3 cam assemblies (which include two adjustable cam segments per cam). The Allen-Bradley 803-B3RH rotation cam limit switch operates at a capacity of 10 Amps (with its snap action mechanism) and at a shaft rotation velocity of 150 RPM. The opening and closure of each cam is 14 degrees minimum and 346 degrees maximum; it comes with 3 cams. The operational temperature of the Allen-Bradley 803-B3RH rotation cam limit switch fluctuates from -22 to 150 degrees Fahrenheit (-30 to 60 degrees Celsius) and offers a higher temperature when it is in storage mode.

The Allen-Bradley 803-B3RH rotation cam limit switch features a right-hand shaft extension, which enables this unit to operate on processes or machines where a second shaft is fully required so that they can both be compatible. The Allen-Bradley 803-B3RH rotation cam limit switch comes with a type one enclosure that protects it from dirt or dust, being ideal for an indoor environment. The approximate length of this unit is 4.38 inches (111.1 millimeters) and the approximate shipping weight is 23 pounds (10.4 kilograms).
