803-F912

The Allen-Bradley 803-F912 is a Style F rotating cam limit switch with a Type 1 and 13 enclosure that has 9 circuits available. It is a heavy-duty switch with a long operating life expectancy that comes with a spring-loaded cam-roller assembly that is mounted to the cam switch contact base. The rotating cam limit switch’s external dwell time and timing adjustments can be configured even while the device is moving or operating. The adjustments can be made by using a screwdriver. Like other Style F switches, the 803-F912 rotating cam limit switch has 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, a standard left shaft extension, a maximum shaft speed of 150 RPM, and a cam duration of a minimum of 12 degrees and a maximum of 348 degrees. The 803-F912 switch is ideal for use with machines with repetitive operation cycles with correlated shaft rotation and machine motion.

Users can mount the 803-F912 switch on any plane and at any angle, as it is capable of rotating equally well in either direction. Its non-operating or storage temperature range is -30 to 93 degrees Celsius and its operating temperature is -30 to 66 degrees Celsius. This switch also has typical shaft torques of 7 pounds on an inch when the cam roller rides up the cam ramp, 0.5 pounds on an inch with the cam roller in the lowest position or valley, and 3 pounds on an inch when the cam roller rides on the highest position or lobe. The 803-F912 switch has approximate measurements of 17.56 x 15.31 x 7.66 inches and weight of 20 pounds or 9.1 kilograms.
