Allen-Bradley 800T-FX D4 Emergency Stop Button

The Allen-Bradley 800T-FX D4 Emergency Stop Button is a 30 mm push-pull E-stop from the 800T family, featuring a red FX head with a 45 mm mushroom profile and two-position push-pull action for rapid machine shutdown. It uses a D4 contact block configuration, designed for installation with 800T push-pull devices to deliver a two-position emergency stop function. The red cap provides immediate visibility, and the unit is intended for use with 800T contact blocks, including NCLB self-monitoring variants, to meet safety circuit needs. When paired with the appropriate blocks, 800T-FX emergency stops comply with EN ISO 13850 and EN/IEC 60947-5-5 safety standards, making them suitable for guarding conveyors, presses, and other industrial machinery requiring a fast, unambiguous stop.
