803-P4LH

The 803-P4LH is an Allen-Bradley manufactured rotating cam Limit Switch that has 4 circuits, 25 Amps, and a maximum shaft speed of 400 RPM. It belongs to the “P” style of Bulletin 803 rotating Cam limit switches. In addition to this, it has an N.C Double Break Contact and between 2 and 12 independent Cam operators. The 803-P4LH has an estimated weight of 8.63 pounds, with heavy duty adjustable cam segments, Vibration resistant spiral lock, and locking Nuts. For durability with use and heavy operations, the 803-P4LH has solid cast Iron side plates and a base that is made of heavy-duty steel. It also has a conduit entrance on each side and is built to last a long time and to be effective in use. Similarly to other Bulletin 803 devices, the 803-P4LH makes use of a cam mounted upon a shaft. The basic working principle is that as the shaft rotates, the contacts are accentuated by the cams. The Cam’s positions on the shaft determine the time when the activation of the circuit would take place within the 360° cycle of rotation.

The 803-P4LH has a Right Shaft Extension Standard that can be modified to a Left Extension standard. It also has room for modification of the external adjustment sprocket. The 803-P4LH has a cam duration of 11 to 349 degrees. The 803-P4LH functions with a type 1 enclosure, together with some other styles within the series. This enclosure is a general purpose enclosure that serves to protect against light and dust particles, as well as preventing contact with live parts. The 803-P4LH is the ideal rotating cam Limit switch for longevity and quality.
