803-B44XRY16T01

The 803-B44XRY16T01 is a 1980 Allen Bradley Rotating Cam Limit Switch. This Rotating Cam Limit Switch has four wholly serviceable circuits. The physical specifications of this Allen Bradley limit switch include a shipping weight of approximately 39 pounds (17.7 kilograms) and dimensions that are around 10.81 x 11.88 inches. The 803-B44XRY16T01 is not a typical 803 Style “B” limit switch; this is due to the fact that it has been modified to a large extent in order to include a speed reducer and a double shaft extension. This module’s speed reducer has a gear ratio of 16:1; as one of the main functions of the speed reducer, it decreases the 803-B44XRY16T01’s input power source rate of motion to realize desired output speeds. The rotating cam limit switch also has internal dwell and timing adjustments. The time at which the circuit is actuated within the rotation cycle is largely determined by the position of the cam on the shaft. Angular degree scales are usually implanted on the mounting place or shaft to ensure that there is no difficulty when making settings to the switch.

To avoid complications, always ensure that the bolts are tightened and the cover is carefully installed when setting the cam in position. The 803-B44XRY16T01 is impressive due to its heavy-duty nature. It’s a device that is mainly manufactured for long life operation. The limit switch is rated for a NEMA Type 4 & 13 enclosure. The Type 4 & 13 enclosures are usually dust-tight, watertight and oil tight industrial enclosures. The lobe of the 803-B44XRY16T01 is the high position of the cam segment. Contrary to that, the valley is the low position of the cam segment. The lobes are designed to push against the cam roller assembly in order to activate the circuit; the cam valley then moves onward to the cam roller assembly, returning the contact to its original state. Similarly to the rest of the Style “B” 803 Rotating Cam Limit Switches, the 803-B44XRY16T01 has a maximum shaft rotation speed of 150 Revolutions Per Minute. The switch also has snap action contacts that are rated for a 10A continuous current.
