Overview
The Allen-Bradley 800T-H2D1 is a 30mm 2-position maintained selector switch from Rockwell Automation’s rugged 800T series of pilot devices. This model features a black knob actuator, 1 normally open (N.O.) contact block, and is built with a corrosion-resistant die-cast metal bezel. With a NEMA Type 4/13 rating, it is ideal for use in oily, dusty, and wet industrial environments where reliable manual control is essential. Non-illuminated design keeps costs down for applications where indication is not required.
Key Features
- Maintained Operation: Black knob stays in position when released, ideal for start/stop and run/stop circuits
- NEMA 4/13 Enclosure Rating: Watertight and oiltight protection for harsh industrial settings
- 1 Normally Open (N.O.) Contact Block: Standard Allen-Bradley modular contact design for simple circuit integration
- Corrosion-Resistant Bezel: Chrome-plated die-cast metal construction for durability
- Standard Knob with White Insert: Easy-to-grip operator with clear positioning visibility
- Screw Terminals: Reliable field wiring connections without additional connectors
- Mechanical Reliability: Over 1 million operations rated mechanical durability
