1. **Naming Rule (digit 4‑digit 11 definition)**
(1) digit 4: Detection principle
DB: Background‑suppression diffuse‑reflective
(2) digit 5: Light source type
R: Red light
(3) digit 7: Sensing setting range
‑ Large‑spot: 35‑250 mm
‑ Small‑spot: 25‑300 mm
(4) digit 8: Output type
N: NPN, P: PNP
(5) digit 9: Output status
3: Switchable Light‑ON / Dark‑ON
(6) digit 10: Cable / connector requirement
‑ Blank: Pre‑formed cable
‑ A: M12 connector type; /X: small‑spot variant suffix
(7) digit 11: Special requirements
‑ /X : Small‑spot special suffix; no suffix for large‑spot.

3. **Detection Principle**
Background‑suppression diffuse‑reflective type. Eliminates interference from background objects, detects target object by receiving reflected light from object surface.**Standard detecting object: white matte paper**.
4. **Sensing Setting Range**
‑ Large‑spot model: 35‑250 mm
‑ Small‑spot model: 25‑300 mm
5. **Main Model Versions**
Available with pre‑formed cable or M12 connector; NPN / PNP outputs optional.
6. **Key Features**
‑ Strong anti‑interference performance with background‑suppression function
‑ Multiple built‑in protection circuits (reverse‑connection, over‑current, short‑circuit protection)
‑ Response time: 1 ms (large‑spot), 2 ms (small‑spot)
‑ IP65 protection degree
‑ Housing material: ABS; lens / display window: PC
‑ Operating temperature: ‑25 ℃ ~ +55 ℃
‑ Dual‑colour indicator for operation & stability status
7. **Operation Mode**
Switchable Light‑ON / Dark‑ON mode via adjustment knob.
8. **Output Options**
NPN or PNP transistor open‑collector output.
