Allen-Bradley 800T-B2 Electronic Timing Relay

Allen-Bradley 800T-B2 is a 30.5 mm black pushbutton actuator from the Bulletin 800T family, featuring an extended head and a momentary, non-illuminated action that ships without internal contacts so you can pair it with compatible 800T contact blocks to complete a control circuit. Designed for rugged industrial panels, it carries a Type 4/13 designation (NEMA) and is intended for use in harsh environments where a durable operator input is required. The B2 variant has no contacts installed, meaning you select and attach the appropriate contact configuration separately to implement functions such as start/stop, reset, or interlock in your automation system, with the extended head aiding operation in tight panel layouts. As part of the 800T family, this actuator uses standard 30 mm mounting and is compatible with a broad range of 800T accessories and enclosures, making it a versatile option for control stations where a robust, non-illuminated momentary input is needed.
