803-A7X

The Allen-Bradley 803-A7X is a Style A rotating cam limit switch featuring 7 circuits, a Type 1 enclosure, and a double shaft extension. This Style A switch also comes with a 150 RPM maximum shaft speed, a cam duration that ranges from 14 degrees minimum to 346 degrees maximum, and 25 Amp. N. C., or normally closed, double break contacts. Also installed on the heavy duty 803-A7X switch is a spring-loaded cam-roller assembly that is mounted to the contact base and it features internal dwell and timing adjustments that the user can configure with custom settings, but only when the device is not in motion. This switch has the capacity to rotate well in a clockwise or a counterclockwise direction. You can use this switch for machines that have operating cycles that are repetitive and that have correlated machine motion and shaft rotation without affecting the switch’s longevity because it is designed to have a long-life expectancy. If mounted and operated properly, the 803-A7X can operate at full heavy-duty power with minimum maintenance.

The typical shaft torques of the 803-A7X rotating cam limit switch are 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, and 3 pounds on an inch when the cam roller rides in the highest position. The 803-A7X also has a storage temperature that ranges from -30 to 93 degrees Celsius and an operating temperature that ranges from -30 to 66 degrees Celsius. This switch has an approximate weight of 15 kilograms or 33 pounds
