803-EF2RHRY08T01

The Allen-Bradley 803-EF2RHRY08T01 is a Style EF rotating cam limit switch that comes with 2 circuits, a right-hand shaft extension, and a speed reducer that has a gear ratio of 8:1. It is a heavy-duty switch that has a long machine life span and it is suitable for use with machines that have repetitive operation cycles with correlated machine motion and shaft rotation. The 803-EF2RHRY08T01 switch is equipped with a cam duration that ranges from a minimum of 15 degrees to a maximum of 360 degrees, a maximum shaft speed of 150 RPM, and 25 Amp. N. C. or normally closed double break contacts, which are standard features of Style EF switches. This switch also has an external time adjustment that is configurable even when the device is in motion, an internal dwell adjustment that users can modify only when the device has been stopped, and a spring-loaded cam-roller assembly that is mounted to the contact base.

The enclosure rating of the 803-EF2RHRY08T01 rotating cam limit switch is Type 13 and it is mountable on any plane, with the capacity to rotate well in either direction no matter what plane it is mounted on or what angle it is mounted at. Its operating temperature ranges from -30 to 66 degrees Celsius, while its non-operating temperature is -30 to 93 degrees Celsius. This switch comes with typical shaft torques of 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-EF2RHRY08T01 also weighs approximately 11.3 kilograms or 25 pounds.
