Omron E2E-X5ME1 Inductive Proximity Sensor

Status: Old model discontinued (legacy E2E series), superseded by E2E-NEXT series

Modellinterpretation

E2E: Omron Standard induktiver Näherungssensor Serie

X5M: Nicht abgeschirmt (non-flush mount), nominal sensing distance 5 mm, M12 threaded barrel

E: DC 3-Leiter

1: NPN normalerweise offen (NEIN)

Grundlegende elektrische Spezifikationen

Verkabelungsdefinition (3-wire Cable)

Braun: DC+ (Macht positiv)

Blau: 0 V (Power Negative)

Schwarz: NPN-Signalausgang

Betrieb: When metal approaches within 5 mm, black wire conducts to blue wire; yellow LED indicator illuminates.

Installationshinweise

1. Nicht abgeschirmter Typ, do NOT flush-mount into metal bore. Maintain metal clearance around sensing face; flush mounting will drastically reduce sensing distance.
2. Supplied with 2 pcs M12 lock nuts.
3. Actual sensing distance decreases for non-ferrous targets (Kupfer, Aluminium).

Discontinued Model Replacement Recommendations

1. Genuine Omron Upgrade: E2E-NEXT series E2E-X5C112-M1TJ, M12 cable type, 5 mm ungeschirmt, NPN-NR, improved performance and full compatibility.
2. Inländisches Äquivalent: M12, non-shielded 5 mm, NPN-NR, DC10-30V, IP67 proximity sensor.

Allgemeine Fehlerbehebung

1. LED leuchtet nicht: Verify brown/blue power polarity and 10-30 VDC supply.
2. LED lights but no output: Incorrect load wiring. For NPN output, connect load between brown positive and black signal wire.
3. Shortened sensing distance: Sensor is sunken into metal, or target material is non-ferrous.

Replacement Options for E2E-X5ME1

Original Part: E2E-X5ME1, M12, ungeschirmt (Sn=5 mm), DC 3-Leiter, NPN Normally Open NO, 2 m Kabel, IP67. Legacy E2E series discontinued.

Critical requirements: M12 barrel, non-flush mount, 5 mm Schaltabstand, NPN-NR, DC10-30V, 3-wire 2-meter cable (Brown-Blue-Black).

1. Genuine Omron Official Replacements (E2E-NEXT series — Preferred)

Verdrahtung: Brown = Power+, Blue = 0 V, Black = NPN output. LED operation identical to E2E-X5ME1.

2. Omron Legacy Stock / Aus zweiter Hand (Only for emergency maintenance; not for new projects)

E2E-X5ME1-Z: Revised suffix variant, identical specifications, old stock only.

Notiz: High counterfeit risk. Do not specify for new equipment.

3. Other Imported Brand Drop-in Equivalents (1:1 parameter match)
4. Schneider XS2-M12MA230

M12 non-shielded 5 mm, NPN-NR, DC12-24 V, 2 m Kabel, IP67; compatible mounting dimensions and wiring.

2. Pepperl+Fuchs NBB5-12GM50-E0

M12, Sn=5 mm, NPN-NR, 3-wire 2 m cable; superior noise immunity, ideal for high-frequency applications.

4. Inländische Alternativen (Kostenoptimiert, retrofitting / spare parts)

Spezifikationen: M12, non-shielded 5 mm, NPN-NR, DC10-30V, 2 m output, IP67

1. LJ12A3-5-Z/BX: General-purpose domestic sensor, 5 mm ungeschirmt, NPN-NR, kostengünstig.
2. GC-E2E-X5ME1: Form-fit copy of Omron unit, identical housing dimensions for direct field replacement.

⚠️ Replacement Precautions

1. Non-shielded sensor must not be flush-mounted into metal bore. Maintain same installation clearance as original, otherwise sensing performance degrades.
2. NPN wiring remains unchanged: connect load between brown positive supply and black signal output.
3. If PLC input is PNP type, above models cannot be used; select PNP-NO variant instead.
4. E2E-NEXT delivers improved response frequency and metal interference resistance compared to legacy E2E-X5ME1, drop-in compatible for most scenarios.

🌍 Environmental Ratings

🧵 3-wire Cable Pinout

Braun: DC Power Positive (+)

Blau: DC Power Negative (0 V)

Schwarz: NPN Signal Output

NPN wiring rule: Connect load between brown positive supply and black signal wire. Do not connect black wire to 0 V.

Betrieb: 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 (bewertet)

SUS304 Stainless steel: ca. 3.5-4 mm

Aluminium: ca. 2-2.5 mm

Messing / Kupfer: ca. 1.5-2 mm

⚠️ Critical Installation Instructions

1. Never flush-mount non-shielded sensor into metal housing. Maintain metal clearance around sensing face; flush mounting causes reduced range or total failure.
2. Side-by-side sensor installation: keep metal separation ≥15 mm between units to prevent mutual interference & Fehlauslösung.
3. Sensing distance reduces if target size is smaller than standard test piece.
