Product description

The Allen Bradley 802T-W3B is a standard duty limit switch equipped with a plunger actuator. This design is suitable for detecting linear movement or the presence of an object directly in its path. It features a rugged die-cast zinc housing for durability and is rated for 10A at 300V, compliant with NEMA 1, 2, 3, 4, 6, and 13 enclosure types.

This limit switch is commonly used in applications where a component directly actuates the switch by pressing its plunger, such as in end-of-travel detection on linear actuators, gate or door position sensing, and within assembly jigs. Industries like automotive, aerospace, and general manufacturing benefit from its straightforward and reliable operation.

Stanlo Automation, a veteran-owned supplier of surplus industrial automation parts, offers the Allen Bradley 802T-W3B. We are dedicated to providing reliable components at competitive prices, ensuring your equipment repairs and upgrades are efficient and cost-effective.

This plunger-style limit switch is ideal for replacing existing switches in applications requiring direct linear actuation. Ensure the mounting dimensions and electrical ratings match your requirements.

Technical note

Expert tip

The plunger actuator on the 802T-W3B requires a direct, perpendicular force to activate. Ensure the moving part aligns properly to avoid side-loading the plunger, which can reduce its lifespan.
