About 803-NK38

The Allen-Bradley 803-NK38 is a Cam Kit for Rotating Cam Limit Switch from series 803. This kit is intended to be used to put together cam assembly for the bulletin 803 rotating cam limit switch. The 803-NK38 cam kit includes two cams and auxiliary hardware for one circuit. There are two pieces of the cam assembly (moon-shaped cam segments), three screws, three spacer washers, three screw nuts, and manual for kit usage with technical data.  Cam segments are rotated and joined with available locking nuts in a way to accomplish desired timing and dwell setting for the control circuit. In this way, a user determines machine operation, because feedback signal from the rotating cam limit switch is further processed in machine’s control logic. A user will position the cam on the shaft (set timing) to determine when the circuit will activate during the 360°rotation cycle.



The size of the joined cam segments lobe will determine the circuit activation time (dwell). When you finish adjustment, lock cam elements position with provided nuts and spacers. Dwell setting for the 803-NK38 assembly limits include the NC contact opening from 108 to 189 degrees while the NO contact remains closed 171 to 252 degrees. When setting the mechanical adjustments, check that the lobes overlap without a gap to provide a continuous cam surface, in order to provide desired contact operation without glitches. Push down and firmly seat joined cam segments against the shaft assembly in order to avoid possible damage to the device. Allen-Bradley stopped manufacturing the 803-NK38 on October 31, 2007.
