803-B84X

The Allen-Bradley 803-B84X is a rotating cam limit switch that features 8 circuits and a double shaft extension. This heavy-duty cam switch has a spring-loaded cam-roller assembly mounted to the contact base and it is used for machines that have operation cycles that are repetitive and where the shaft rotation is correlated to the motion. The internal dwell time and the timing of the 803-B84X switch are adjustable, but only when the device is not moving. The switch can also rotate equally well in either a clockwise or a counterclockwise direction. This switch also has a maximum shaft speed of 150 RPM, a cam duration that ranges from a minimum duration of 14 degrees and a maximum duration of 346 degrees and 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, which are all standard features of Style B rotating cam limit switches.

The ambient storage temperature of the 803-B84X rotating cam limit switch ranges from -30 to 93 degrees Celsius and its ambient operating temperature range is -30 to 66 degrees Celsius. This switch also has typical shaft torques of 7 pounds on an inch when the cam roller rides up the cam ramp, of 0.5 pounds on an inch with the cam roller in the valley or its lowest possible position, and of 3 pounds on an inch when the cam roller rides on the lobe or its highest possible position. Weighing approximately 16.3 kilograms or 36 pounds, the 803-B84X switch has a Type 1 enclosure and it can be mounted on any plane.
