Omron E3FA Photoelectric Sensor

Model: E3FA-DP12 Type: Diffuse-Reflective (M18 Cylindrical)

---

1. General Description

The Omron E3FA-DP12 is a high-performance, general-purpose photoelectric sensor in a standard M18 cylindrical housing. It operates on the diffuse-reflective principle, meaning it detects objects by the light reflected directly off the object itself, without the need for a separate reflector or receiver.

This model features a robust plastic housing, a high-power red LED for easy alignment, and a standard PNP output. It is designed for reliable detection in standard industrial applications such as packaging, logistics, and material handling.

Key Features 🎯

• Simple Alignment: High-power visible red LED makes aligning the sensor with the target easy.

• Diffuse Reflective: Detects objects directly (no reflector required).

• Adjustable Sensitivity: Features a potentiometer (trimmer) to adjust the sensing range for different target colors or background conditions.

• Robust Housing: M18 plastic body, sealed to IP67/IP69K for high resistance to washdowns.

• Standard Output: PNP transistor output.

3. Wiring (Standard 4-Wire PNP)

The E3FA-DP12 typically comes with a 4-wire cable to allow selection between Light-ON and Dark-ON modes.

• Brown (BN): +V (10-30 VDC)

• Blue (BU): 0V (GND)

• Black (BK): Output (Signal)

• Pink (PK) / White (WH): Mode Selection

  • Connected to +V (Brown): Light-ON (Output active when object is present)

  • Connected to 0V (Blue) or Open: Dark-ON (Output active when object is absent)
