Package Contents

• 1 × Omron E2E-X2D1-M3G Inductive Proximity Sensor (Genuine New Original)

Important Notes

• Confirm exact part number (E2E-X2D1-M3G) before ordering — not interchangeable with NC (Normally Closed) variant E2E-X2D2-M3G.

• Sensing range is rated for standard mild steel targets (Fe360, 8×8mm). Smaller or non-ferrous targets will reduce effective range.

• Do not exceed rated supply voltage (24V DC max). Overvoltage will damage the sensor.

• Professional installation recommended. Refer to Omron E2E Series datasheet for full mounting and wiring instructions.

• IP67 protection is valid only when the M8 connector is fully mated with a compatible IP67-rated cable connector.

Frequently Asked Questions (FAQ)

Q1: What is the sensing range of the Omron E2E-X2D1-M3G?

The E2E-X2D1-M3G has a nominal sensing range of 2mm for standard mild steel (Fe360) targets. The effective range may be shorter for smaller targets or non-ferrous metals such as aluminum or stainless steel. Always test in your actual application to confirm detection distance.

Q2: What is the difference between E2E-X2D1-M3G and E2E-X2D2-M3G?

The E2E-X2D1-M3G is a Normally Open (NO) output model — the output is OFF when no target is detected and switches ON when a target enters the sensing range. The E2E-X2D2-M3G is the Normally Closed (NC) equivalent, where the output is ON by default and switches OFF upon target detection. Choose NO or NC based on your PLC input logic and fail-safe requirements.

Q3: Is this sensor compatible with my PLC?

Yes. The E2E-X2D1-M3G operates on 12–24V DC and uses a DC 2-wire output, making it compatible with virtually all standard industrial PLC input modules (Siemens, Mitsubishi, Omron, Allen-Bradley, etc.). Check that your PLC input module supports 2-wire (leakage current) sensors, as some high-sensitivity inputs may require a bleed resistor.

Q4: What does IP67 mean for this proximity sensor?

IP67 means the sensor is fully protected against dust ingress (IP6X) and can withstand temporary immersion in water up to 1 meter depth for up to 30 minutes (IPX7). This makes it suitable for wash-down environments, coolant splash, and dusty factory floors — but it should not be used for continuous submersion.

Q5: How do I wire the E2E-X2D1-M3G to my control panel?

For DC 2-wire wiring: connect Pin 1 (Brown) to +V (12–24V DC), Pin 3 (Blue) to 0V/Ground, and connect your load (PLC input or relay) in series between the output (Pin 4, Black) and ground. The sensor switches current through the load when a metal target is detected. Pin 2 (White) is not connected in the 2-wire model.

Q6: Can the E2E-X2D1-M3G detect non-ferrous metals like aluminum or copper?

Inductive proximity sensors primarily detect ferrous metals (iron, steel) at rated range. Non-ferrous metals such as aluminum, copper, and stainless steel can also be detected, but at a reduced sensing distance — typically 30–60% of the rated range depending on the material. For reliable detection of non-ferrous targets, consider a sensor with a longer rated range or a capacitive sensor.

Q7: What is the maximum switching frequency of this sensor?

The E2E-X2D1-M3G supports a maximum switching frequency of 1,500 Hz, meaning it can detect up to 1,500 ON/OFF transitions per second. This makes it suitable for high-speed counting, rotary encoder replacement, and fast-moving conveyor applications.

Q8: Is the E2E-X2D1-M3G a genuine new Omron product?

Yes. The E2E-X2D1-M3G sold here is a genuine new original Omron component supplied in original manufacturer packaging. It has not been repaired, refurbished, or remanufactured. We source directly from authorized supply chains to ensure product authenticity and quality.
