Compact Body. Proven Everywhere.
The M12 barrel is the most common thread size in industrial sensing, fitting tight spaces and threading into standard through-holes. The Omron E2E-X3D1-N is Omron's standard shielded inductive proximity sensor in M12 form, featuring 3mm rated sensing distance, DC 2-wire output, and normally-open switching. It detects ferrous metal targets without contact, generates no wear, and handles environmental conditions including oil mist, coolant, vibration, and washdown.

Shielded Design Benefits
The shielded construction focuses the electromagnetic sensing field forward through the sensor face rather than radiating laterally. This allows flush mounting in metal brackets, plates, or machine frames without surrounding metal disturbing the sensing field or causing false detections.
DC 2-Wire Wiring
The 2-wire design runs the output signal in series with the load on just two conductors, simplifying wiring and reducing cable bulk. Key parameters:
- Switching capacity: 3 to 100 mA
- Leakage current: 0.8 mA max.
Environmental Durability
- IP67 rated - dustproof and withstands temporary submersion
- Oil-proof construction resistant to cutting oil exposure
- Solid potted internal circuitry for vibration resistance
- Operating range: −25°C to +70°C
- Nickel-plated brass barrel for corrosion resistance
Dual LED Indicators
- Red LED - indicates when output is active (target detected)
- Green LED - indicates proper power and sensing range during setup
Common Applications
- CNC and machine tool part-present confirmation
- Conveyor and material handling position detection
- Robotic cell end-of-arm tooling sensors
- Automotive assembly component verification
- Packaging equipment metal detection

Frequently Asked Questions
Can the E2E-X3D1-N be mounted flush in a metal bracket?
Yes - the shielded design enables flush mounting in metal. The electromagnetic field is focused forward, so surrounding metal doesn't interfere. For multiple sensors, maintain minimum spacing of 30mm side by side or 20mm face to face to prevent interference.
What is the minimum load current requirement, and will it work with my PLC input?
The sensor requires a minimum load current of 3mA. Most standard PLC discrete input cards draw 5mA to 10mA and work without issue. The sensor passes up to 0.8mA leakage current when off, which is typically compatible with modern industrial PLC hardware.
What is the difference between the E2E-X3D1-N and the E2E-X3D1-U?
Both share identical sensing specifications. The E2E-X3D1-N uses oil-resistant PVC cable, while the E2E-X3D1-U uses polyurethane (PUR) cable that is mechanically reinforced for applications with repeated flexing, aggressive chemicals, or abrasion risk.
How do I adjust the sensing distance on the E2E-X3D1-N?
This sensor has fixed sensitivity set at the factory for 3mm sensing distance. The effective distance can be varied between 0 and 4.8mm by adjusting the physical gap between sensor face and target, but internal gain is not user-adjustable.
The E2E-X3D1-N is listed as discontinued or replaced - should I be concerned about availability?
Omron integrated DC 2-wire E2E models into the E2E NEXT series in October 2022. However, the E2E-X3D1-N remains widely stocked worldwide and continues to be used extensively as a replacement part for existing installations.
