The Allen-Bradley 803-A124RH rotating cam limit switch weighs about 45 pounds and it comes with a right-hand shaft extension and with 12 circuits. It can fit inside a Type 4 or a Type 13 enclosure, it can be mounted on any type of plane, and has the capacity to rotate clockwise or counterclockwise. This rotating switch has internal dwell and timing settings that are adjustable, but they can only be adjusted when the switch is not rotating. The 803-A124RH also features a spring-loaded cam-roller assembly that is mounted to the switch’s contact base. With a heavy duty industrial rating and a long product lifespan, the 803-A124RH switch is usually used with machines that have operation cycles which are repetitive, especially for operation cycles and applications where the shaft’s rotation and motion are correlated. The 803-A124RH can also be customized for specific applications.

The typical shaft torques of the 803-A124RH switch, per cam, are 0.5 pounds on an inch for applications with the cam roller in the valley, 7 pounds on an inch for applications where the cam roller needs to ride up the cam ramp, and 3 lb-in for applications when the cam roller needs to ride on the lobe. The series Allen-Bradley 803 series switches, such as the 803-A124RH switch, can operate at a temperature range between -30 and 66 degrees Celsius and they can be stored at a temperature between -30 and 93 degrees Celsius.This switch is a Style A switch and it features a cam duration range of as little as 14 degrees to as much as 346 degrees, its maximum shaft rotation speed is 150 RPM, and it has 25A-rated N. C. (normally-closed) double break contacts.
