The Allen Bradley 803-P3X cam limit switch is used to control the speed and rotations of heavy machinery. The 803-P3X controls the rotations by opening and closing independent circuits at required angular positions. The switch is capable of sensing and controlling the rotation of a machine at various points and positions. The 803-P3X has external dimensions of 28 X 21 X 21 inches, (28 inches in length, 21 inches in width and 21 inches in height). The switch has a 25 Ampere N.C. (Normally Closed) double break contact and can achieve a maximum of 400 RPM speed in either direction. No tools are necessary to adjust the cam setting.

The Allen Bradley 803-P3X cam limit switch comes in a Type 1 enclosure, with and without cams. It has 2 to 12 independent cam operators that can be adjusted without affecting the other circuits. The cam duration can be set from an 11-degree minimum to a 349-degree maximum. The 803-P3X is designed for heavy machinery and needs very little maintenance if used with care. It comes with dwell adjustments and internal/external timings and is widely used to control both assembly and packing machinery, steel forming and heavy metals, punch presses, and injection molding machines. The Allen Bradley 803-P3X cam limit switch belongs to the family of 803 series cam limit switches, designed to control heavy rotating machinery in various industries. The cam limit switch comes with double shaft arrangements and double-break or snap-action contacts. It is designed in a way that it can be easily mounted at any angle or plane.
