Product Overview

The E2E-X8MD1 2M is the M12 brass-body, 8 mm unshielded (non-flush) inductive proximity sensor with DC 2-wire polarized normally-open output and a 2 m pre-wired oil-resistant PVC cable. The E2E is Omron's flagship general-purpose inductive line — the right pick when the application needs reliable metal detection in a DC circuit that is wired like a switch contact rather than like a sensor with separate load and supply. The DC 2-wire form factor is the classic 'limit switch replacement' — the sensor acts like a contact closure (current sinks through the load when a target is detected) rather than a sourcing output stage.

Decoding the E2E-X8MD1 model number

The E2E model code follows a strict naming convention: E2E = standard cylindrical inductive family; X = standard oil-resistant PVC cable (vs S = enhanced PUR cable, R = robot-grade, U = polyurethane); 8 = 8 mm sensing distance; MD = M12 unshielded / 2-wire DC polarized (M = M12 body, D = 2-wire DC; the shielded sibling is E2E-X8MD1-S or 2S with the S prefix indicating shielded mounting); 1 = normally-open (NO). The 2M suffix means 2 m pre-wired cable (no suffix = special variant per the Omron datasheet note system).

DC 2-wire polarity wiring — pinout is different from 3-wire

The E2E-X8MD1 2M uses the same 2 conductors for both supply power and load current — there is no separate load terminal. Wire the brown conductor (+V) to the positive supply (12 to 24 VDC) and the blue conductor (0 V) to the load, with the load's other terminal connected to 0 V (ground). When a target is detected, the sensor sinks current through the load to ground (NO contact closure = current flows when target present).

Pick the E2E-X8MD1 2M over 3-wire when:

The load is a relay coil or solenoid that operates directly on the sensor current — DC 2-wire sensors can switch up to 100 mA through the load, which is enough to drive a small relay coil directly. The 2-wire form factor also minimizes wiring errors in the field (no +V, 0V, output, ground — just two wires and a load). And the leakage current spec (0.8 mA max) is critical for high-impedance loads: if the load is a PLC input with high input impedance (> 10 kΩ), the 0.8 mA leakage may be enough to trigger the input falsely when the sensor is OFF.

Buying Checklist

  • Pick E2E-X8MD1 2M for M12 brass 8 mm unshielded DC 2-wire NO inductive sensor with 2 m pre-wired PVC cable
  • Pick E2E-X8MD1-M1 for M12 4-pin connector instead of pre-wired cable

FAQ for E2E-X8MD1 2M

What does "DC 2-wire polarized" mean on the E2E-X8MD1 2M?
DC 2-wire means the sensor uses the same 2 conductors (brown and blue) for both supply power and load current — there is no separate 'output' wire as there would be on a 3-wire sensor. Polarized means the sensor requires strict polarity: brown = +V (12-24 VDC positive) and blue = 0V (return / load).
Can the E2E-X8MD1 2M drive a relay coil directly?
Yes — the DC 2-wire output can switch up to 100 mA at 30 VDC, which is enough to drive small relay coils directly (a typical 24 VDC relay coil draws ~10-30 mA; a 12 VDC automotive relay coil draws ~150 mA — pick a 24 VDC relay for headroom). Connect the relay coil between the blue wire and 0 V (ground); the brown wire goes to +V supply.
What's the difference between E2E-X8MD1 2M and E2E-X8MD1?
E2E-X8MD1 with no suffix is the connectorized M12 version per the Omron datasheet — but in practice this base SKU is rarely sold without a connector variation. E2E-X8MD1-M1 adds an M12 4-pin connector (prewired pigtail, ~30 cm). E2E-X8MD1 2M (this SKU) has a 2 m pre-wired cable. The electrical specs are identical (8 mm sensing, 0.8 kHz response, 12-24 VDC supply, 100 mA load, IP67 body), only the connection method differs.
What's the sensing distance on non-ferrous metal targets with the E2E-X8MD1 2M?
The 8 mm nominal sensing distance is specified for iron (ST37 / SPCC). Other materials reduce the sensing range by approximately: stainless steel (304) = 0.85× = 6.8 mm; aluminum (6061) = 0.55× = 4.4 mm; brass = 0.55× = 4.4 mm; copper = 0.45× = 3.6 mm. For aluminum bracket detection, mount the sensor at <4 mm; for thin stainless foil detection, mount at <6 mm.
