803-A24RY4T01

The 803-A24RY4T01 Rotating CAM Limit Switch manufactured by Allen-Bradley is a 2-circuit heavy-duty circuit control device with a standard left-hand shaft extension and a NEMA Type 1, 4, or 13 enclosure. It is used with heavy-duty dedicated processes, where a machine’s motion corresponds to the shaft rotation. The device, like most devices in the 803 series, has a rotating switch which can move in any direction, and a cam mounted on a rotating shaft. The 803-A24RY4T01 is a style A device with a 25A normally-closed contact, and it has a factory-built speed reducer with a 4:1 Gear Ratio. Its normally-closed contact has 150A/15A, 75A/7.5A and 30A/3A MAKE/BREAK ratings at 120 Volts AC, 240 Volts AC, and 600 Volts AC, respectively, with 1800 VA, MAKE/BREAK real power, and a DC voltage rating of 230 to 250 Volts DC at 1A. The 803-A24RY4T01 has a higher cam segment called the lobe, along with a lower segment called the valley, and a keyway slot that connects the rotating shaft to machines.

It has a cam timing which corresponds to the position of the cam on the shaft and relative to the keyway slot, and the cam timing is a measured in degree angle. The 803-A24RY4T01 has an angular range of 14 to 346 degrees. It also has a cam dwell time, which is a measurement of the size of the lobe, and heavy-duty machinery are controlled by the device timing and dwell time settings. It has a working temperature limit of -22 to 150 degrees Fahrenheit with a storage temperature range of -22 to 200 degrees Fahrenheit. The 803-A24RY4T01 weighs about 9.1 pounds, with net shipping dimensions of 4.38 x 5.69 x 7.88 inches, and it has both CSA and UL certification.
