803-B6RH

The Allen-Bradley 803-B6RH is a rotating cam limit Style B switch that comes with 6 circuits and a right-hand standard shaft extension. Installed on this cam limit switch is a spring-loaded cam-roller assembly that is mounted onto the contact base and it features internal dwell time and timing settings, which users can adjust when the device is at a complete stop, and it is also capable of rotating well in both directions, which is common to all 803 series switches. Specific features common to switches in the Style B line, including the 803-B6RH switch, are a maximum shaft speed of 150 RPM, 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, and a cam duration ranging from a minimum of 14° to a maximum of 346°. Weighing 31 lbs or 14.1 kg, this heavy-duty 803-B6RH switch has a Type 1 enclosure and is mountable on any type of plane.

With a long product life, the 803-B6RH switch is ideally used for machines with repetitive operation cycles that have correlated motion and shaft rotation, as well as various applications such as injection molding machines, waterway lock operations, packing machines, and punch presses. Its normal shaft torques are 0.5 pounds on an inch with the cam roller in the valley, 7 pounds on an inch when the cam roller rides up the cam ramp, and 3 pounds on an inch pounds when the cam roller rides on the lobe. The storage temperature of the 803-B6RH switch is from -30-93 °C, and the operating temperature ranges from -30-66 °C.
