803-P4RA

The 803-P4RA is a 4-circuit customizable rotating cam switch with operator cams, which is manufactured by Allen Bradley. The 803-P4RA is recognized as a “P” style design and has N.C. cam opened contacts which have a current capacity of 25 Amps. The shaft speed is 400 RPM maximum. This module’s shaft extension is on its right-hand side as a standard. The 803-P4RA has a speed reducer gear ratio of 40:1, which is identified by the “RA” in the suffix of the product code. The 803-P4RA requires storage at a temperature of -22 to 200 degrees Fahrenheit. It comes in type 1 general purpose enclosure; the dimensions of this rotating cam switch are 5.63 inches (h), 7.13 inches (l), and 7.06 inches (w). The rotating shaft length for the 803-P4RA is 1.5 inches and this module’s shipping weight is around 18 pounds (or 8.2 kilograms). The 803-P4RA contains four internal switches which can be activated based on the rotation of the shaft.

This spring-loaded assembly of cam roller is mounted on the contact base, which activates the contacts with a continuous current capacity of 25 Amps. With the shaft rotating when the cam design and the dwell timing of the operations are determined, the cams will activate the switches in sequential orders to produce the corresponding outputs for other machines and equipment. These 803-P4RA  cam switches are usually used in various applications where the operations are sequential and repetitive, hence being used in presses, forming machines, various assembly machines, and packaging and labeling machines.
