The Allen Bradley 802T-ATP limit switch is characterized by its durable metal construction and oiltight design. This switch utilizes a rotary lever arm actuator, enabling it to manage a maximum travel angle of about 90°. It operates through snap-acting contacts, commonly configured in a 4-circuit layout of 2 normally open and 2 normally closed circuits.
For contact operation, the switch requires a nominal activation travel of 13° and has a reset travel distance of up to 7°. This ensures precise control and efficient operations. The rated current for alternating current (AC) is 10 A, making the switch suitable for various electrical systems.
With an IP67 protection rating, the 802T-ATP is well-suited for applications in harsh environments, providing reliable functionality against dust and water exposure. The conduit entry is configured for a ½″-14 NPT connection, facilitating straightforward installation. To activate the switch, a torque of 0.45 N·m is required. Wire connections can be made through sturdy screw terminals, providing secure connectivity. This switch can function effectively across a wide operating temperature range, from -18 °C to +110 °C, making it versatile for diverse usage scenarios in industrial settings.
