Flush Mount Capability
The shielded design directs the electromagnetic field forward through the sensor face, allowing flush installation in metal brackets and machine frames without interference. This eliminates the need for plastic spacer rings or minimum standoff requirements, providing maximum design flexibility in compact installations.
2-Wire DC Simplicity
The DC 2-wire output architecture simplifies installation by requiring only two conductors, making it ideal for replacing mechanical switches and reducing wiring complexity. This design offers direct compatibility with most PLC input cards while maintaining reliable operation.
High-Speed Performance
With a 1,000 Hz maximum response frequency, this sensor handles high-speed applications including gear tooth counting, indexing, and rotary target detection with ample performance margin for standard industrial applications.
Robust Environmental Protection
IP67 certification ensures complete protection against dust ingress and temporary water immersion. The oil-resistant sensing face and PVC cable jacket provide additional protection against cutting oils, coolants, and high-pressure washdown environments common in machine tool applications.
Dual LED Indicators
- Green Setting Indicator: Confirms power and target detection within sensing range during installation

Frequently Asked Questions
Does the E2E-X3D1-N detect non-ferrous metals like aluminum or stainless steel?
While optimized for ferrous metals, this sensor will detect non-ferrous metals with reduced sensing distance (typically 40-50% of rated distance for aluminum). Verify detection reliability with actual target material during installation.
Can multiple sensors be mounted close together?
Yes, with minimum spacing of 30mm side-by-side or 20mm facing each other to prevent mutual interference. For closer spacing, consider alternative-frequency variants.
What is the difference between NO and NC output?
Normally Open (NO) output closes when target detected (E2E-X3D1-N). Normally Closed (NC) output opens when target detected (E2E-X3D2-N). Most applications use NO for presence detection logic.
What is the 3mA minimum load requirement?
DC 2-wire sensors require minimum 3mA load current for proper operation. Most industrial PLC inputs draw 5-15mA, well above this threshold.
Is the E2E-X3D1-N being replaced by newer models?
While Omron offers E2E NEXT series with enhanced features, the E2E-X3D1-N remains available and is the direct replacement for existing installations requiring identical form, fit, and function.
