Allen-Bradley 802T-B Limit Switch

The Allen‑Bradley 802T‑B Limit Switch is a compact, oil‑tight electromechanical limit switch built for harsh industrial environments. It features NEMA Type 4 and 13 oil‑tight construction, a non‑plug‑in body, and a top push‑rod actuator, delivering reliable end‑of‑travel sensing in confined spaces. This 802T‑B version provides two independent circuits within a single, whole‑switch assembly, enabling dual‑channel signaling for sequencing, interlocking, or safety interlocks without the need for plug‑in modules. Typical applications include conveyors, presses, packaging lines, and other automated equipment where robust protection against dust, moisture, and oil is required and space is limited. The top‑rod actuation promotes straightforward operation by parts contacting the switch during travel, while the rugged housing supports repeated cycling in demanding production environments. Designed to integrate with standard Allen‑Bradley control systems, 802T‑B switches are part of Rockwell Automation’s general‑purpose limit switch family, offering a durable, serviceable solution for industrial position sensing where two circuits are often used to monitor separate control contacts.
