803-B54RH

The Allen-Bradley 803-B54RH rotating cam limit switch has 5 circuits and 2 cams. Its 1st cam is at the 5th position from the right-hand shaft extension and its second cam at the 4th position from the shaft. This rotating cam limit switch has a spring-loaded cam-roller assembly which is mounted to the contact base and this switch also comes with features like internal dwell and timing settings that the user can adjust, but which are only configurable when the device is not in use. Present on all Style B switches, including the 803-B54RH switch, is a 150 RPM maximum shaft speed, 1 10 Amp. snap action 1 N. O. (normally open) contact and 1 N. C. (normally closed) contact, and a minimum of 14 degrees and a maximum of 346 degrees for a cam duration.

Its operating temperature ranges from -30-66 degrees Celsius, while its non-operating temperature is from -30-93 degrees Celsius. The 803-B6RHRB switch also operates with typical shaft torques of 0.5 pounds on an inch with the cam roller in the valley, 7 pounds on an inch when the cam roller rides up on the cam ramp, and 3 pounds on an inch when the cam roller rides on the lobe. With a long product lifespan, this switch can be used for heavy-duty operations. This switch is specifically used for machines with repetitive operation cycles that correlate shaft rotation and machine motion. The 803-B6RHRB has a Type 4 and 13 enclosure, and it can rotate well in either direction when mounted on any plane. Its approximate shipping weight is 49 pounds or 22.2 kilograms.
