Emergency Stop Switches / E-Stop Switches Emergency Stop Unibody
Research Notes
1. What this is
XA1E-BV4U02T-N is an IDEC XA-series 16mm unibody emergency-stop switch (mushroom, pushlock turn/pull-reset, direct-opening NC safety contact). This specific variant is Maintained (pushlock; turn or pull to reset).
2. Part-number decode
- Series: IDEC XA — 16mm emergency-stop
- Operation: Maintained (pushlock; turn or pull to reset)
3. Compatibility & ordering
Panel cutout: 16mm. Unibody construction — the operator and contact are a single assembly. Cross-reference by size, operation, contact arrangement, and color to an equivalent from another IEC command-switch line (Schneider Harmony, Allen-Bradley 800F/800T, Siemens 3SU, Eaton M22) if IDEC is unavailable.
4. Data-quality note
This page is generated by decoding IDEC's published part-number scheme for the XA series (grounded in IDEC's series datasheets and IDEC USA's catalog). The structured fields above follow directly from the code.

Referensi Cepat Instalasi
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.

Pemecahan Masalah
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.
