Product Description
The Allen Bradley 803-P4LHX is a robust rotating cam switch designed for demanding industrial applications involving cyclic or rotational movements, particularly where machine motion is linked to shaft rotations. Part of the "P" style 803 series, it offers versatile customization with accessories, mounting options, and handles. It operates up to 400 rpm, with adjustable cam durations between 11 and 349 degrees. Housed in a Type 1 enclosure, the 803-P4LHX features 2 to 12 independent cam operators and a 25 Amp N.C double break contact. Available with or without cams, the "P" style includes internal timing and dwell adjustments that must be made while the device is stationary, requiring cover removal and cam bolt manipulation. Its standard right-side shaft extension and angular degree scales on the cam mounting plate simplify setup.
