The Allen-Bradley Bulletin 802T is a heavy-duty oiltight limit switch built for harsh industrial environments where reliable position sensing cannot be compromised. With an IP67 and NEMA 6P-rated die-cast metal enclosure, snap-acting silver alloy contacts, and a plug-in body design, the 802T serves conveyor systems, transfer machines, automatic turret lathes, milling and boring machines, and radial drills where coolant, dust, and mechanical shock are constant.

What safety features does the 802T offer?

Safety-rated versions include direct opening action per ISO 14119, ensuring NC contacts forcibly open even under welded-contact conditions (tested to 10 N). Rated as a Category 1 device per EN 954-1, the 802T integrates into dual-channel safety circuits to achieve Category 3 or 4 system-level safety performance when paired with a suitable safety relay.

Which actuator heads are available?

The 802T accepts a wide range of interchangeable operating heads: standard and roller lever, wobble stick, cat whisker, top and side push (plain and roller), and air-operated actuators. This modularity allows a single switch body to cover diverse mechanical actuation requirements across a machine, simplifying spare parts inventory.

What are the electrical ratings and contact options?

Contacts are rated A600 / AC-15 with 10 A continuous thermal current, handling 7200 VA make and 720 VA break at 600 V AC. Configurations include 2-circuit (1 N.O. + 1 N.C.) and 4-circuit (2 N.O. + 2 N.C.) options with M20 conduit entry. The plug-in body design enables quick field replacement without rewiring.
