803-PL8X

The Allen-Bradley 803-PL8X is a Style P fewer cams rotating cam limit switch that has a double shaft extension and 8 circuits available. Installed on this switch is a spring-loaded cam-roller assembly that is mounted to the contact base and it features internal dwell time and timing settings that the user can adjust when the device is not moving. The heavy duty 803-PL8X rotating cam limit switch is also capable of rotating in either a clockwise or a counterclockwise direction and it has a Type 1 enclosure that allows the user to mount it on any plane and to mount it at any angle. Other features present on this switch that is standard to Style P switches are a cam duration that ranges from 11 degrees minimum to 349 degrees maximum, a maximum shaft speed of 400 RPM, and 25 Amp. N. C. or normally closed double break contacts.

With an approximate weight of 22 pounds or 10 kilograms, the 803-PL8X rotating cam limit switch is ideal for use with machines with operation cycles that are repetitive and have their shaft rotation correlated to the general machine motion, like steel-forming machines. Its operating temperature range is from -30 to 66 degrees Celsius, while the storage temperature ranges from -30 to 93 degrees Celsius. The 803-PL8X switch also comes with typical shaft torques of 3 pounds on an inch when the cam roller rides on the lobe, of 7 pounds on an inch when the cam roller rides up the cam ramp, and of 0.5 pounds on an inch with the cam roller in the valley.
