The 802T-AU model from Allen Bradley is a robust oiltight limit switch designed for dependable operation across various industrial applications. This switch mounts using a non-plug-in, manifold style, which simplifies integration into existing setups. It features a spring-return rotary lever as the actuator, allowing for both clockwise (CW) and counterclockwise (CCW) rotation, thereby enhancing its versatility.
With a dual circuit configuration, it includes a contact setup of one normally open (NO) contact and one normally closed (NC) contact, allowing for nuanced control within system operations. The switch is rated for AC pilot duties according to NEMA A600 standards, suitable for handling voltages up to 600V. Furthermore, its maximum continuous current rating is 10 A, ensuring sufficient power handling for various applications.
The 802T-AU limit switch supports up to 3 A under AC-15 conditions at 240V, while also managing 2.2 A under DC-13 conditions at 125V. Notably, it is equipped with a maximum breakaway torque of 0.34 N-m (3 lb-in), which assists in minimizing unnecessary wear during operation.
The mechanism allows an operating travel of nominally 16.5° until it reaches the contacts. For resilience in functionality, maximum reset travel is established at 8°, while the overall maximum mechanical travel extends to 43°. This diverse travel capability ensures that the Allen Bradley 802T-AU can effectively accommodate a range of operational scenarios.
