803-F1212RH

The Allen-Bradley 803-F1212RH is a rotating cam limit switch that features 12 circuits, a right-hand shaft extension, and Type 1 and Type 13 enclosure ratings that can be mounted on any plane and mounted at any angle. Typically used for machines that have operation cycles that are repetitive that have their shaft rotation correlated to the general motion, this switch can handle heavy-duty operations and has a long life expectancy. If used properly, the switch will need very little maintenance. Features of the 803-F1212RH cam switch include a 150 RPM maximum shaft speed, a cam duration that ranges from a minimum of 12 degrees to a maximum of 348 degrees, and 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts. It is also equipped with external dwell and timing adjustments that are modifiable with a screwdriver even when the device is in motion, and with a spring-loaded cam-roller assembly mounted to the contact base. Rotation in either direction is possible with the 803-F1212RH rotating cam limit switch.

The 803-F1212RH has a storage temperature range of -30 to 93 degrees Celsius, as well as an operating temperature range of -30 to 66 degrees Celsius. The typical shaft torques of this switch are 3 pounds on an inch when the cam roller rides on the lobe, 7 pounds on an inch when the cam roller rides up the cam ramp, and 0.5 pounds on an inch with the cam roller in the valley. The 803-F1212RH has approximate dimensions of 17.56 x 15.31 x 7.66 and it weighs 19 pounds or 8.6 kilograms.
