803-A6RH

The Allen-Bradley 803-A6RH is a Style A rotating cam limit switch which features a right-hand shaft extension installed and 6 available circuits. It is typically used for machines with repetitive operation cycles that have correlated motion and shaft rotation. It comes with 25 Amp. N. C. or normally closed double break contacts, a maximum shaft speed of 150 RPM, and a cam duration that ranges from 14 degrees minimum to 346 degrees maximum, which are standard to Style A switches. The 803-A6RH rotating cam limit switch is also equipped with internal dwell time and timing settings that can be adjusted. However, these settings can only be adjusted when the machine is not in motion. The 803-A6RH also has a spring-loaded cam-roller assembly that comes mounted onto the cam switch’s contact base.

The operating temperature of the 803-A6RH rotating cam limit switch is from -30 to 66 degrees Celsius (-22 to 151 degrees Fahrenheit), while its storage temperature ranges from -30 to 93 degrees Celsius (-22 to 200 degrees Fahrenheit). It also has typical shaft torque ratings of 0.5 pounds on an inch with the cam roller in the lowest possible position or the “valley,” of 7 pounds on an inch when the cam roller rides up the cam ramp from the lowest position to the highest, and of 3 pounds on an inch when the cam roller rides on the highest possible position or the lobe. This switch has a Type 1 enclosure and is a heavy-duty switch with a long-life expectancy. The 803-A6RH weighs approximately 29 pounds or 13.2 kilograms and it is capable of rotating well in either direction.
