3. **Detection Principle**
Background‑suppression diffuse‑reflective type. Suppresses background interference, detects target by receiving reflected light from object surface.**Standard detecting object: white non‑glossy paper**.
4. **Sensing Range**
Setting range: 25‑300 mmDetection range: 20‑300 mm
5. **Main Model Versions**
Available with pre‑formed cable or M12 connector; NPN / PNP outputs optional.
6. **Key Features**
‑ Background‑suppression function, reduces background object interference
‑ Multiple built‑in protection circuits (reverse‑connection protection, output over‑current protection, output short‑circuit protection)
‑ Response time: ≤3 ms
‑ IP65 protection degree
‑ Housing material: ABS; lens / display window: PC
‑ Operating temperature: ‑25 ℃ ~ +55 ℃Storage temperature: ‑25 ℃ ~ +65 ℃ (no icing, no condensation)
‑ Spot size: approx. Φ10 mm (at 300 mm distance)
‑ Dual‑colour indicator: red for operation status, green for stability status
7. **Operation Mode**
Switchable Light‑ON / Dark‑ON mode via adjustment knob.
8. **Output Options**
NPN or PNP transistor open‑collector output.1. **Naming Rule (digit 4‑digit 11 definition)**
