Allen-Bradley 800T-FXD4 Push Button with Contact Block

Allen-Bradley 800T-FXD4 is a 30 mm push-button operator from the 800T family that ships with an integrated 800T-XD4 contact block. It is designed for panel mounting in industrial control stations and provides a robust manual input for control circuits, including start/stop, signaling, or interlock functions within automation systems. The included XD4 contact block supports two-wire terminations using 14–18 AWG conductors, enabling straightforward wiring from the block to relays or controllers while maintaining a compact operator footprint. As part of the modular 800T platform, this configuration allows operators and blocks to be swapped or upgraded within the same physical footprint to fit different logic needs, without changing the overall panel layout. The 30 mm size balances visibility and accessibility with space constraints in control panels, making it a common choice for machine control and process automation environments.
