Product Overview
The E2E-X2D1-M1 is the M8 brass-body, 2 mm shielded (flush-mountable) inductive proximity sensor with DC 2-wire polarized normally-open output and an M12 4-pin metal connector on the cable end — the right pick for tight-space flush-mountable installations where a quick-disconnect is needed. The 'M8' in the part name refers to the barrel / sensing-head body; the 'M1' suffix is the connector type — M12 4-pin male metal connector per IEC 60947-5-2. Common confusion: some catalogs list this as 'M12 sensor' because of the M1 connector, but the barrel thread is M8.
Decoding the E2E-X2D1-M1 model number
The full model code follows the E2E family convention: E2E = standard cylindrical inductive; X = standard oil-resistant PVC cable family (vs S = enhanced PUR for coolants, R = robot-grade, U = polyurethane); 2 = 2 mm sensing distance (vs 8 = 8 mm, 14 = 8 mm M18 body, etc.); D = DC 2-wire polarized output (vs Y = DC 3-wire, R = DC 2-wire non-polarized, E = AC 2-wire); 1 = normally-open (NO — '2' would be NC); M1 = M12 4-pin connector (vs M3 = M8 connector, no suffix = pre-wired 2 m, blank = factory pre-wired).
DC 2-wire polarization — wiring on M12 connector pins
The M12 connector follows IEC 60947-5-2 pinout for DC 2-wire: pin 1 = +V (brown wire inside the cordset), pin 4 = 0V (blue wire). When a target is detected, the sensor sinks current through the load (which is connected between the blue wire and ground). Polarity is strict — reversed polarity prevents switching and stresses the internal protection diode.
Why pick M8 shielded over M12 unshielded (E2E-X2D1-M1 vs E2E-X8MD1 2M)
Two key advantages for M8 shielded 2 mm: (1) flush-mountable in ferrous metal — install directly into a steel bracket or aluminum frame with no clearance gap, allowing higher packing density than unshielded M12 8 mm which needs 36 mm gap. (2) higher switching frequency 1.5 kHz — the small sensing face and shorter magnetic loop let the sensor respond in 0.67 ms vs the E2E-X8MD1's 0.8 kHz = 1.25 ms, allowing faster detection in high-speed packaging, labeling, and printing lines.

Best-Fit Applications
- Gear-tooth counting on a gearbox output shaft — the E2E-X2D1-M1 sits 1.5 mm above the gear teeth, sensing each tooth-rotation.
- Cam-position detection on a pneumatic indexing table — small M8 barrel allows tight-pitch mounting next to the cam disc; the.
- Drill-bit-in-spindle confirmation on a CNC machining center — the M8 sensor confirms the drill bit is fully retracted; 2-wire output.
- Wire-feed speed confirmation on a welding wire feeder — the M8 sensor detects the rollers on the wire-feed mechanism; 2-wire.
Buying Checklist
- Pick E2E-X2D1-M1 for M8 shielded 2 mm DC 2-wire NO inductive sensor with M12 4-pin connector
- Pick E2E-X2D1 2M for M8 shielded 2 mm DC 2-wire NO with pre-wired 2 m cable instead of M12 connector
- Pick E2E-X2D2-M1 for NC — pick for fail-safe logic where 'sensor blocked = output ON'
- Pick E2E-X2Y1-M1 for NPN DC 3-wire — pick for modern PLC inputs that expect separate signal output
- Pick E2E-X8MD1 2M for M12 body 8 mm unshielded with pre-wired 2 m — pick for longer range, no flush-mount
- Pick E2E-X3D1-M1 for M12 body 3 mm shielded — same connector style but longer barrel for threaded-mount

FAQ for E2E-X2D1-M1
Is the E2E-X2D1-M1 an M8 or M12 sensor?
The E2E-X2D1-M1 is an M8 body (sensing-head barrel thread) with an M12 connector on the cable end. The 'M1' suffix in the E2E model code means 'M12 4-pin connector' — it's the connector type, not the body size. The thread size is M8 × 1.0, which is the small 8 mm barrel used in tight-space applications. The M12 connector is the standard IEC 60947-5-2 4-pin male plug on the back of the sensor, which mates with cordset XS3F-M421-402-A.
Can the E2E-X2D1-M1 be wired directly to a relay coil?
Yes — the DC 2-wire output can switch up to 100 mA at 30 VDC, enough to drive small relay coils directly. Wire the relay coil between the sensor's 0 V line (pin 4 on the M12 connector, blue wire on the cordset) and chassis ground; connect +V (pin 1, brown) to 24 VDC supply. The sensor acts as a NO contact closure between brown and blue when a target is detected, allowing current to flow through the load.
What's the sensing distance on non-ferrous metal targets with the E2E-X2D1-M1?
The 2 mm nominal sensing distance is specified for iron (SPCC/ST37). Other materials reduce the sensing range by approximately: stainless steel (304) = 0.85× = 1.7 mm; aluminum (6061) = 0.55× = 1.1 mm; brass = 0.55× = 1.1 mm; copper = 0.45× = 0.9 mm. For aluminum-detecting at <1.1 mm, the E2E-X2D1-M1 is borderline — consider the E2E-X3D1-M1 (3 mm shielded M12) with its 3/4 = 2.25 mm aluminum range if the application is consistent aluminum-target detection.
Can the E2E-X2D1-M1 be flush-mounted into a steel bracket?
Yes — that's the entire point of the 'shielded' / flush-mount designation. The E2E-X2D1-M1 has an internal metal collar around the PBT sensing face that contains the magnetic field, allowing the body to be set in a steel or aluminum bracket with 0 mm side clearance from ferrous material.
