803-F912X

The 803-F912X is a Rotating Cam Limit Switch from the series of 803 switches manufactured by Allen-Bradley. It belongs to a condition sensing control type of devices. A product like his can be of vital importance in heavy-duty industrial control systems with repetitive cycles of operations. The 803-F912X found its use on machines such as punch presses, packing machines, cranes, and similar applications. The 803-F912X rotating cam limit switch is connected to the target machine over its shaft. This is how target machine movement is transferred to the shaft rotation on the sensing device. The shaft rotates with 9 cam operators attached to it are operating 10A rated single pole double throw contacts at various positions (user adjustable). The contacts change back their state after dwell time (user adjustable in the 12 to 348 degree range). Both parameter adjustments are conducted externally. There is no need to stop the machine for these settings to be performed. Double shaft extension is provided for this rotating cam limit switch.

The designers combined first-class materials, outstanding workmanship, and serious standards to produce this highly reliable, world-class control device. You can find a number of parts on this device, including steel-made bottom support bordered by rugged cast iron plates, 0.75-inch diameter shaft, nine cam segments with 10A snap action 1 NO / 1 NC contacts, and cabling entries on each side. This 803-F912X sensing switch has the dimensions of 17.56 inches x 7.00 inches x 3.25 inches (446.1 x 177.8 x 82.6 millimeters). The product’s shipping weight is approximately 19 pounds (8.6 kilograms). It is positively tested to work within -22 to 150 degrees Fahrenheit (-30 to 66 degrees Celsius) temperature range. Allen-Bradley stopped manufacturing the 803-F912X in 2007.
