Allen-Bradley 800T-FX6D4 Push-Pull Operator – 30.5mm, 2-Position, Red Mushroom Head, 1 NCLB

The 800T-FX6D4 is built into a rugged, die-cast zinc housing and is designed to survive the most demanding industrial environments. The "D4" suffix refers to the specific contact block included: a 1 Normally Closed Late Break (NCLB) contact. This "Late Break" feature is often used in safety or timing circuits where you want the contact to remain closed for a fraction of a second longer than a standard NC contact during actuation.
