Overview
The Allen-Bradley 800T-FXTQH24RA1 is a rugged illuminated emergency stop pushbutton operator from the industry-standard 800T series. This 30.5 mm unit combines full-voltage 24V AC/DC LED illumination with a mechanically robust push-pull/twist-release mechanism designed to meet EN-418 and IEC 60947-5-5 emergency stop standards when paired with NCLB (normally closed late break) contact blocks.
Key Features
- Illuminated LED design — Full-voltage 24V AC/DC rated LED lamp for clear visual indication in dark or cluttered control stations
- Push-pull/twist-release operator — Mechanical interlock prevents accidental activation; requires deliberate pull or pull-then-twist action to reset
- Red mushroom head cap — 30.5 mm standard mushroom head, no finger-safe guards (standard configuration)
- Type 4/13 enclosure rating — Sealed against dust and moisture when used in properly specified stations; suitable for indoor industrial environments
- NCLB contact configuration — Standard 1 normally closed late break + 1 normally open contact block; meets emergency-stop compliance requirements when using certified contact blocks
- Proven industrial design — Part of the 800T/800H family trusted across machine control, motor starting, and safety-critical applications
Technical Specifications
This unit is designed as an operator module compatible with 800T contact block assemblies and power modules. Key electrical and mechanical parameters:
- Operates with contact blocks rated for emergency stop applications per EN-418 and IEC 60947-5-5
- Mushroom head (push-pull) operator with full mechanical detent action
- LED illumination: full-voltage 24V AC/DC
- Standard shallow or deep contact block compatibility
- Mounting: 30.5 mm panel cutout with standard barrel assembly
Typical Applications
- Machine tool emergency stop stations (CNC, mills, lathes)
- Process control panel master shutdown buttons
- Industrial automation equipment requiring redundant safety circuits
- Factory floor operator interface systems
- Conveyor and material handling system emergency stop arrays
- Hazardous location (Class I, Div. 2) equipment when paired with certified contact blocks
Compatibility & Replacements
The 800T-FXTQH24RA1 operator interfaces with Allen-Bradley 800T contact blocks and power modules. This unit is the operator only — it must be combined with appropriate back-of-panel contact block assemblies (e.g., 800TC-XA, 800TC-XD4S self-monitoring blocks) to create a complete pushbutton station. Users can also build complete stations by adding the operator to 800T enclosure bases and configuring with standard or sealed contact blocks depending on application requirements. The part number suffix indicates:
- F = Illuminated
- X = Push-pull/twist-release mechanism
- TQH = 2-position push-pull with NCLB contacts, LED illumination
- 24 = 24V full voltage rating
- RA1 = Red mushroom head, standard configuration
For replacement or upgrade options, consult with an authorized Allen-Bradley distributor to verify compatibility with your existing 800T stations or to explore equivalent 800H units for corrosion-resistant (Type 4/4X/13) applications.
