Brown: DC + (Power Positive)
Blue: 0 V (Power Negative)
Black: NPN signal output
Operation: When metal approaches within 5 mm, black wire conducts to blue wire; yellow LED indicator illuminates.
Installation Notes
- Non-shielded type, do NOT flush-mount into metal bore. Maintain metal clearance around sensing face; flush mounting will drastically reduce sensing distance.
- Supplied with 2 pcs M12 lock nuts.
- Actual sensing distance decreases for non-ferrous targets (copper, aluminum).

Discontinued Model Replacement Recommendations
- Genuine Omron Upgrade: E2E-NEXT series E2E-X5C112-M1TJ, M12 cable type, 5 mm non-shielded, NPN-NO, improved performance and full compatibility.
- Domestic Equivalent: M12, non-shielded 5 mm, NPN-NO, DC10-30 V, IP67 proximity sensor.
Common Troubleshooting
- LED does not light: Verify brown/blue power polarity and 10-30 VDC supply.
- LED lights but no output: Incorrect load wiring. For NPN output, connect load between brown positive and black signal wire.
- Shortened sensing distance: Sensor is sunken into metal, or target material is non-ferrous.
Replacement Options for E2E-X5ME1
Original Part: E2E-X5ME1, M12, non-shielded (Sn=5 mm), DC 3-wire, NPN Normally Open NO, 2 m cable, IP67. Legacy E2E series discontinued.
Critical requirements: M12 barrel, non-flush mount, 5 mm sensing distance, NPN-NO, DC10-30 V, 3-wire 2-meter cable (Brown-Blue-Black).
- Genuine Omron Official Replacements (E2E-NEXT series — Preferred)
| Replacement Part | Description | Difference |
| E2E‑X5C112‑Z 2M | Cable‑type direct replacement, 5 mm non‑shielded, NPN‑NO, 2 m cable, compatible mechanical mounting. | Slightly shorter housing; enhanced electrical protection & noise immunity; identical pin‑out, drop‑in replacement without wiring modification. |
| E2E‑X5MC112‑M1 | M12 connector version, no cable; requires separate M12 straight cable. | For quick‑disconnect applications; cannot reuse original 2 m cable. |
Wiring: Brown = Power+, Blue = 0 V, Black = NPN output. LED operation identical to E2E-X5ME1.
- Omron Legacy Stock / Second-hand (Only for emergency maintenance; not for new projects)
E2E-X5ME1-Z: Revised suffix variant, identical specifications, old stock only.
Note: High counterfeit risk. Do not specify for new equipment.
- Other Imported Brand Drop-in Equivalents (1:1 parameter match)
- Schneider XS2-M12MA230
M12 non-shielded 5 mm, NPN-NO, DC12-24 V, 2 m cable, IP67; compatible mounting dimensions and wiring.
- Pepperl+Fuchs NBB5-12GM50-E0
M12, Sn=5 mm, NPN-NO, 3-wire 2 m cable; superior noise immunity, ideal for high-frequency applications.
- Domestic Alternatives (Cost-optimized, retrofitting / spare parts)
Specs: M12, non-shielded 5 mm, NPN-NO, DC10-30 V, 2 m output, IP67
- LJ12A3-5-Z/BX: General-purpose domestic sensor, 5 mm non-shielded, NPN-NO, cost-effective.
- GC-E2E-X5ME1: Form-fit copy of Omron unit, identical housing dimensions for direct field replacement.
⚠️ Replacement Precautions
- Non-shielded sensor must not be flush-mounted into metal bore. Maintain same installation clearance as original, otherwise sensing performance degrades.
- NPN wiring remains unchanged: connect load between brown positive supply and black signal output.
- If PLC input is PNP type, above models cannot be used; select PNP-NO variant instead.
- E2E-NEXT delivers improved response frequency and metal interference resistance compared to legacy E2E-X5ME1, drop-in compatible for most scenarios.

🧵 3-wire Cable Pinout
Brown: DC Power Positive (+)
Blue: DC Power Negative (0 V)
Black: NPN Signal Output
NPN wiring rule: Connect load between brown positive supply and black signal wire. Do not connect black wire to 0 V.
Operation: When metal enters sensing zone, black-blue path conducts and LED turns on; opens when target moves away.
📎 Sensing-Distance Derating by Target Material
Nominal 5 mm applies only to ferrous steel
Iron / Cold-rolled steel: 5 mm (rated)
SUS304 Stainless steel: approx. 3.5-4 mm
Aluminum: approx. 2-2.5 mm
Brass / Copper: approx. 1.5-2 mm
⚠️ Critical Installation Instructions
- Never flush-mount non-shielded sensor into metal housing. Maintain metal clearance around sensing face; flush mounting causes reduced range or total failure.
- Side-by-side sensor installation: keep metal separation ≥15 mm between units to prevent mutual interference & false triggering.
- Sensing distance reduces if target size is smaller than standard test piece.
