The 803-PL12LH switch is a Style P rotating cam limit switch that has been designed by Allen-Bradley/Rockwell Automation. This part is specially designed for use in packing machines, steel, and metal-forming machines, punch presses and lock operations applications. It can be used in any application that requires the control of objects such as a gate opener or for counting different materials that pass a certain point in the overall application process. The Allen-Bradley/Rockwell Automation 803-PL12LH Style P rotating cam limit switch comes with a high-speed and low-cost internal adjustment that makes it affordable and powerful at the same time. This switch package includes only the operator switch. The cams will need to be ordered separately. This switch has room for 12 circuits.

The Allen-Bradley/Rockwell Automation 803-PL12LH Style P rotating cam limit switch has been designed with an extra feature that consists of a single shaft extension that is located on the left side of the switch. This extension improves the operations of the switch and enables it to have a deeper involvement in the applications where it is currently being used. The recommended temperature for the switch during operation should be between -30 to 66 degrees Celsius. If there are no liquids in the switch’s environment, there will be no issues with it operating at temperatures below 0 degrees Celsius. If there are liquids in the environment, ice may form on the switch if it is operating below freezing. The Allen-Bradley/Rockwell Automation 803-PL12LH Style P rotating cam limit switch has a double break contact of 25 Amps and it can reach up to 400 RPM. This switch has room for more cams than other switches in the 803 series.
