803-PL4LH

The Allen-Bradley 803-PL4LH is a Style P rotating cam limit switch featuring 4 circuits and a left-hand shaft extension. It also comes with a spring-loaded cam-roller assembly that is mounted to the switch’s contact base and its internal dwell time and timing settings are adjustable. However, it is only possible to adjust these settings when the machine is not in motion. The 803-PL4LH rotating cam limit switch comes with the standard features of Style P switches, such as a maximum shaft speed of 400 RPM, 25 Amp. N. C. or normally closed double break contacts, and a cam duration of 11 degrees minimum and of 349 degrees maximum. The 803-PL4LH is also a heavy-duty switch that has a long operating lifespan and it is suitable for machines that have operation cycles that are repetitive in with the general machine motion and the rotating cam limit switch’s shaft rotation are directly correlated.

The typical shaft torques of the 803-PL4LH Style P rotating cam limit switch are 7 pounds on an inch when the cam roller rides up the cam ramp, they are 0.5 pounds on an inch with the cam roller in the valley, and the typical shaft torques are 3 pounds on an inch when the cam roller rides on the lobe. Its storage temperature ranges from -22 to 200 degrees Fahrenheit and its operating temperature is from -22 to 151 degrees Fahrenheit. The 803-PL4LH has a Type 1 enclosure rating, as well as an approximate weight of 6.4 kilograms or 14 pounds. Users can mount this switch on any plane and it can rotate well in either direction on any plane.
