802XR-AC7

The Allen Bradley Bulletin 802XR series includes the 802XR-AC7 model, which is a sealed contact limit switch. This component is specifically designed for durability and reliability in challenging conditions. It utilizes normally closed (NC) contacts for effective operation, which is ideal for applications where the switch condition must remain closed until a specific action is taken.

It can operate through both clockwise and counterclockwise motions, providing versatility in installation. The actuator is a rotary lever arm, with a maximum travel angle of 42 degrees and a maximum angle for operating contacts set at 16 degrees. For resetting the contacts, the device requires a travel of 9 degrees maximum.

The enclosure is made of metal, offering additional protection in hazardous environments. The switch meets NEMA Type 7 and 9 standards, making it suitable for use in potentially explosive atmospheres. The maximum torque required to activate the contacts is rated at 0.34 Newton-meters (or 3 inch-pounds), ensuring that operations remain efficient.

In terms of electrical characteristics, the contact rating is specified at 1.1 amperes per pole, functioning effectively within a voltage range of 11 to 125 volts DC. This makes it capable of handling various loads while maintaining stable operation. The continuous carrying current rating is set at a maximum of 5 amperes per pole. Overall, the 802XR-AC7 is a versatile limit switch suited for demanding industrial applications.
