현행 제품Eaton M22-I1 Empty 1-Hole M22 Control Station Enclosure (M22-I1-M4)
Eaton M22 enclosed e-stop control station.
일반적인 용도
Complete e-stop in IP67 enclosure. Yellow lid, red mushroom. Mount on wall or machine frame. Standard remote e-stop for Eaton-controlled plants.
Research Notes
1. Overview
The Eaton M22-I1 family (here the M22-I1-M4 variant) is an empty one-element surface-mounting enclosure for the Eaton M22 / RMQ-Titan 22 mm system — a plastic box with one 22 mm hole for a customer-fitted M22 device (pushbutton, E-STOP, selector, or indicator) plus its contact blocks. It ships empty (no operator, no contacts), IP66, for building a single-operator control station. (Data-quality note: this was mis-cataloged as a populated "1-Button E-Stop Station" with a red mushroom and 1 NC contact — the M22-I1 base is an empty enclosure and no source confirms a populated e-stop station under this code. Eaton's actual complete E-STOP stations use different catalog numbers, e.g. M22-PV…/K…/IY…. The exact "-M4" suffix/color was not independently confirmed; the standard M22-I1 is grey top / black base.)
2. User Sentiment
M22 surface enclosures are the standard way to make a stand-alone control station without cutting a panel — install the box, fit the M22 device(s) and contacts you need, and wire it. Trusted RMQ-Titan ecosystem. The trade-off vs. a pre-assembled station is that you populate it yourself, so an operator/contact set is not part of this SKU.
3. Real-World Applications
Building a single-operator surface-mounted control point (start button, E-STOP, selector, or indicator) on a machine, wall, or frame with no panel cutout available.
4. Technical Specifications
- Type: Empty one-element M22 surface-mounting enclosure (1 × 22 mm hole)
- Contents: enclosure only — no operator/contacts included
- Housing: plastic (standard M22-I1: grey top / black base; verify color for the -M4 suffix)
- Sealing: IP66
- System: Eaton M22 / RMQ-Titan, 22 mm
- Approvals: UL, CSA, CE
5. Ordering & Compatibility
Order the empty enclosure plus the required M22 actuator and contact/LED blocks separately. For a ready-made E-STOP station, order a complete Eaton M22 e-stop station SKU (M22-PV…/K…/IY…), not the empty M22-I1 enclosure. Larger enclosures: M22-I2 (2 holes), M22-I3 (3), etc.
6. Known Issues / DQ
- DQ: this is an empty enclosure, not a populated e-stop station — the stored red mushroom / 1 NC / e-stop function were fabricated (same pattern as sibling M22-I1-M1, #432). Corrected; the exact "-M4" color/variant should be verified.
- Practical care: when populating for E-STOP duty, use a genuine red Ø38 mushroom operator + correct NC contacts and confirm the safety category.

M22-I1 base = empty 1-hole M22 enclosure (RS/Eaton). Stored e-stop station (red mushroom 38mm, 1NC) fabricated — same as sibling M22-I1-M1 (#432). Real Eaton e-stop stations use M22-PV.../K.../IY... codes. -M4 suffix/color unconfirmed.

설치 빠른 참조
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.

문제 해결
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.
