Allen-Bradley 802T-R1TD SER.1 Limit Switch

Allen-Bradley 802T-R1TD SER.1 Standard Limit Switch is a Bulletin 802T oil-tight limit switch engineered for rugged industrial environments. This time-delay version uses a pneumatic timing function to produce a delayed electrical signal after actuation, enabling precise sequencing and feedback in control circuits and interlocks. The R1TD designation identifies a rotary lever actuator option, and the unit is specified as two circuits with clockwise-only operation and standard mounting; the 802T-W1 lever can be used to tailor actuation geometry. As part of the 802T family, this device is designed to withstand harsh conditions, with oil-tight construction compatible with demanding applications, and the time-delay is integrated (non-plug-in) for straightforward installations. The SER.1 variant indicates an early or specific revision within the 802T line, and the overall design supports reliable, repeatable timing behavior in production equipment where a timed response on limit switch actuation is required.
