803-A44RY

The Allen-Bradley 803-A44RY switch is a series 803 Rotating Cam Limit switch. This device belongs to the condition sensing switch and controls product family. It is attached to mechanisms in applications where repetitive control operations are required. The 803-A44RY rotating cam limit switch has the ability to open or close independent circuits at user-defined angular positions; it is used for applications such as packing machines, punch presses, and injection molding machines. It can be adjusted to operate in any plane and it can rotate in clockwise and counterclockwise directions. The 803-A44RY has “A style” design form housing. Its number of distinct switching contacts (each with independent cam operator) is four. The current capacity for these provided double break contacts is 25A and the enclosure of the device is a 4 & 13 industrial enclosure (known for its exceptional protection from intrusion of water, dust, and oil). This limit switch is delivered with a left shaft extension.

Any rotating cam limit switch part with “RY” in its order code signifies that the desired gear ratio is not the standard one, and it should be added as a suffix code. (For example, 65TO1; full code example, 803-A44RY65TO1). This is a “Style A” device, and as such has internal dwell and timing adjustments. Internal timing and dwell adjustments are to be set only when the device is not moving. To adjust these parameters, the user must remove the cover, loosen cam nuts, and rotate cams to the desired operating position. When cams are positioned, tighten the cam nuts and return the cover to its appropriate position. The Allen-Bradley 803-A44RY weight is 39 pounds (17.7 kilograms) and its dimensions (shaft excluded) are 274.6 x 301.6 x 173.0 millimeters (10.81 x 11.88 x 6.81 inches). Its operating temperature is -22 to 150 degrees Celsius (-30 to 66 degrees Celsius). This part has not been manufactured by Allen Bradley since 2007.
