803-F912RH

The 803-F912RH, a rotating cam limit switch manufactured by Allen-Bradley, belongs to the Bulletin 803 Rotating Cam Limit switches. Embedded with 9 circuits at 10 Amps and a maximum shaft speed of 150 RPM (Revolutions Per Minute), the 803-F912RH is ideal for heavy-duty applications. It also has a snap action 1 NO and 1 NC. contact and a left shaft extension standard, and functions with a NEMA Type 1 or 13 enclosure. While the machine is in motion, the 803-F912RH comes with an external screwdriver, which can be used to make adjustments for timing and dwell. Between 2 and 12 Independent Cam Operators are present in the 803-F912RH. In some machines, there is a correlation between movement and shaft motion; in such machines, the 803-F912RH can be used as a heavy duty control circuit device. Unlike some others in the same series, the 803-F912RH can function in two directions, operating at the same maximal level in either direction. This enables an adequate field angle coverage.

The 803-F912RH is manufactured to withstand prolonged pressure and long, rugged hours of work. Materials used in its assembly give it the resilience that is needed for quality production. It also has a cam duration between 12 and 348 degrees, and a speed reducer makes up the configuration of the 803-F912RH, connecting via a flexible coupling. Modifications that can be made to the 803-F912RH can be both general and unique. The general modifications include the change to a Right-Hand Extension shaft instead of the traditional Left-Hand extension, which is seen in other series. The option for an Internally Adjustable Cam is a modification that is peculiar to the F-series and is therefore available for the 803-F912RH. The 803-F912RH, manufactured by Allen-Bradley, is an ideal module for applications that require extended durability and quality.
