803-B8XRHRF

The Allen-Bradley 803-B8XRHRF is a rotating cam limit switch featuring a double shaft extension equipped with a right-hand shaft extension, 8 circuits, and a speed reducer that has a gear ratio of 150:1. It also comes with adjustable internal dwell time and timing settings, which the user can adjust when the machine is at a complete stop, and the machine is capable of rotating in either a clockwise or a counterclockwise direction without issue. The 803-B8XRHRF switch also has a 150 RPM maximum shaft speed, 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, and 14 degrees minimum and 346 degrees maximum cam durations, respectively. Also installed on this switch is a spring-loaded cam-roller assembly that is mounted to the contact base.

A heavy-duty switch with a long operating lifespan, the 803-B8XRHRF rotating cam limit switch is typically used for machines that come with repetitive operation cycles with correlated main machine motion and shaft rotation. It has a Type 1 enclosure and it is able to be mounted on any plane at any angle, and it weighs approximately of 36 pounds or 16.3 kilograms. Its typical shaft torques are 0.5 pounds on an inch with the cam roller in the lowest position (valley,) 7 pounds on an inch when the cam roller rides up the cam ramp and 3 pounds on an inch when the cam roller rides in the highest position (lobe.) The 803-B8XRHRF switch also has a storage temperature between -30 and 93 degrees Celsius, as well as an operating temperature between -30 and 66 degrees Celsius.
