Allen-Bradley 802T-W2A Adjustable Limit Switch is a NEMA‑style, heavy‑duty limit switch in the 802T family designed for end‑of‑travel sensing on industrial equipment. The W2A variant uses an adjustable roller lever actuator, enabling precise actuation over a travel range typically cited as about 1.9 to 3.0 inches. In operation, the switch signals the control system when a moving part reaches the preset limit, enabling appropriate stop/start or sequencing actions in machinery. Common applications include conveyors, packaging lines, and presses where reliable limit sensing and a configurable actuator are required.
