Product Overview
The Omron 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. manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
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.
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.

Best-Fit Applications
- Pneumatic cylinder end-of-stroke position confirmation on a packaging machine — E2E-X8MD1 2M mounted on the cylinder body, target = piston.
- Tool-position confirmation on a CNC machining center — multiple E2E-X8MD1 2M sensors confirming tool-changer positions with 0.8 kHz response suitable.
- Door-position feedback on a non-safety machine guard — sensor mounted on the cabinet frame, target = ferrous strike plate; for.
Buying Checklist
- Pick E2E-X8MD1-M1 for M12 4-pin connector instead of pre-wired cable
- Pick E2E-X8MY1 2M for DC 3-wire NPN output — pick for PLC inputs with sourcing-input style
- Pick E2E-X14MD1 2M for M18 brass 8 mm unshielded version with longer body for threaded-mount applications

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.
