Allen-Bradley 800T-A9B Pushbutton Contact Block is a 30 mm flush-head, momentary block designed for use with the 800T family of pushbuttons. It provides two normally open and two normally closed contacts (2 NO, 2 NC) in a single block, enabling independent signaling and interlock wiring within 800T 30 mm operator assemblies. The unit is yellow, non-illuminated, and rated for NEMA 4/13 environments, suitable for washdown, dusty, or industrial settings. As part of the broader 800T/H line of 30 mm pilot devices, this contact block expands a pushbutton's circuit capability with a compact four-contact block.
