The 803-F712RF is a rotating cam manufactured by Allen Bradley.  This 803-F712RF cam is a heavy-duty control circuit device with a stainless steel security cover. The 803-F712RF is usually used with a type of machinery that has a reiterative cycle of operation, while also having a shaft rotation type motion. The 803-F712RF has a baked polyester enamel paint coating with a 30-foot Pre-wired exterior grade cable for signal applications. This module has a standard left shaft extension along with a 150 RPM maximum shaft speed with a Type 1 & 13 enclosure. The industrial-grade 803-F712RF switch by Allen-Bradley is an adjustable, high-quality unit, designed for vigorous operations; as such, this high-quality unit is fitted with an adapter plate, which enables it to be directly commutable.

The 803-F712RF comes along with an external screwdriver-made adjustment for timing and dwell, even when the machine is in operation. This timing, however, remains dependent upon the position of the cam on the shaft, with respect to the Top Dead Center (TDC). This is only possible at the period that the circuit becomes activated by the cam. The one crucial advantage specific to the 803-F712RF is its long life and heavy-duty operation. Similarly to every other cam in the series, the 803-F712RF has elemental mechanical structure components, some of which include a rotating shaft with a speed up to about 400 RPM, a spring-loaded cam roller assembly mounted to the contact base, 2 to 12 cam assemblies with two adjustable segments per cam, and 2 to 12 Independent circuits with a cam-opened contact assembly or a snap action block assembly. The 803-F712RF Shaft assemblies rotate smoothly with precision bearings.
