803-P5LH

The Allen-Bradley 803-P5LH is a Style P rotating cam limit switch that has 5 circuits present and that is equipped with a left-hand shaft extension, instead of the right-hand shaft extension that is typical for Style P switches. These rotating cam limit switches, including the 803-P5LH switch, also have a Type 1 enclosure, a cam duration time that ranges from a minimum of 11 degrees to a maximum of 349 degrees, 25 Amp. rated N. C. or normally closed double break contacts, and a maximum shaft speed of 400 RPM. Also available on the 803-P5LH switch is a spring-loaded cam-roller assembly that is mounted to the contact base and it has internal dwell and timing settings, which can only be configured when the 803-P5LH switch is powered off and not in motion.

With an approximate weight of 6.4 kilograms or 14 pounds, the 803-P5LH rotating cam limit switch is used for machines that have operation cycles that are repetitive and that have shaft rotations which correlate to the main machine’s motion. You can also use this switch for heavy duty functions without worrying about its lifespan. If the 803-P5LH switch is mounted and used properly, it will need minimal maintenance even when operating at full power. It also has 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. The operating temperature of the 803-P5LH switch is from -30 to 66 degrees Celsius and the switch’s non-operating temperature is -30 to 93 degrees Celsius.
