800T-FXP16RA1
AtivoBulletin 800T 30.5mm Red Illuminated Mushroom Push-Pull E-Stop (1NCLB+1NO)
Red illuminated 40mm mushroom-head push-pull e-stop for the Allen-Bradley 800T 30.5mm NEMA system. 120V AC lamp, 1 normally closed late-break and 1 normally open contact. Metal construction.
Aplicações comuns
Found on heavy industrial machinery as an emergency stop. The push-pull mechanism latches in the pushed (off) position and requires deliberate pulling to reset — preventing accidental restart. The 120V illumination makes it visible even in dim conditions. The late-break NC contact ensures the stop signal is maintained until the actuator fully releases. NEMA 4/13 metal body suits oily, dusty plant floors.
Research Notes
1. Overview
The Allen-Bradley 800T-FXP16RA1 is a 30.5 mm illuminated push-pull mushroom pushbutton from Rockwell's heavy-duty Bulletin 800T line — red, maintained two-position (push to actuate / pull to release), with an illuminated (120 V AC) mushroom head and a 1 NCLB + 1 NO contact set (NCLB = normally-closed late-break, a stop-friendly contact). It's a die-cast metal, NEMA Type 4/13 (watertight/oiltight) device, rated to 600 V, UL/CSA/CE/CCC. Push-pull maintained red mushrooms are commonly used as lit STOP / E-STOP operators.
2. User Sentiment
The 800T/800H 30.5 mm line has a reputation for exceptional durability — die-cast metal, sealed operators, decades of field service. An illuminated push-pull mushroom gives a large, lit, latching stop control (push to stop and light, pull to reset). Considerations: it's a heavy, premium 30.5 mm device (vs lighter 22 mm plastic lines), and you confirm the lamp voltage (120 V AC here) and the contact set (1 NCLB + 1 NO).
3. Real-World Applications
A large lit red push-pull STOP / E-STOP on machinery and control panels — push the mushroom to stop (the NC late-break opens; the lamp shows the stopped/active state), pull to reset. The 1 NO can drive a PLC/indicator input.
4. Technical Specifications
- Type: Bulletin 800T 30.5 mm illuminated push-pull mushroom pushbutton, maintained (2-position)
- Color / head: red, Ø40 mushroom head
- Illumination: 120 V AC (incandescent/lamp per catalog)
- Contacts: 1 NCLB + 1 NO (NCLB = normally-closed late-break); screw terminals; up to 600 V
- Enclosure: die-cast metal, NEMA Type 4/13
- Cutout: 30.5 mm
- Approvals: UL, CSA, CE, CCC
5. Ordering & Compatibility
Part of the 800T catalog; the suffix defines head/color/illumination/contacts. Confirm the lamp voltage (120 V AC), the contact configuration (1 NCLB + 1 NO), and that 30.5 mm suits the panel. Uses standard 800T lamps/contact cartridges for service parts.
6. Known Issues
No notable reliability issues — the 800T line is known for longevity. Practical care: match the lamp voltage (120 V AC, not 24 V), verify the contact set (NCLB late-break for stop timing), and note it's a heavy 30.5 mm die-cast device (heavier/pricier than 22 mm lines but far more rugged). For a certified E-STOP, confirm it meets the machine's safety category.

Referência rápida de instalação
Panel cutout: 30.5mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).
Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.
Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

Solução de problemas
E-stop won't reset (twist/pull doesn't release)
Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.
Machine doesn't stop when e-stop is pressed
Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.
Safety relay faults after e-stop reset
The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
