Emergency Stop Switches / E-Stop Switches A4EG-BE2R041
Research Notes
1. What this is
A4EG-BE2R041 is an Omron Omron component — line not recognized.
2. Part-number decode
- Series: Omron Omron (line not recognized)
- Type: switch
3. Compatibility & ordering
Omron makes industrial command switches (A22 22mm, A16 16mm — unitized, contact in the model code), illuminated pushbuttons/pilot lights (A3, M2), and a widely-used B3 PCB tactile-switch family. Match by size, function (pushbutton/selector/indicator/E-stop), colour, illumination, and contact arrangement, then use the Omron datasheet to confirm the exact colour and voltage encoded in the part number.
4. Data-quality note
The exact Omron product line/configuration could not be confidently decoded from this part number. Kept and documented; flagged needs-verification.

Référence rapide d'installation
Panel cutout: 22mm. 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.

Dépannage
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.
