- نظرة عامة على المنتج
- يكتب: Inductive proximity switch, non-flush (cannot be flush-mounted)
- Housing: M18×1 nickel-plated brass; sensing face PBT engineering plastic
- مسافة الاستشعار: Nominal Sn=16 mm, effective operating distance Sr≈16 mm
- الإخراج: PNP NO normally-open, 3-wire DC 10-30VDC, الأعلى. load 200 mA
- واجهة: M12-A-coded 3-pin male plug (NOT 4-pin)

- Standard accessories: 2 pcs M18 lock nuts
- مواصفات التثبيت الميكانيكي (شديد الأهمية: Never sink non-flush sensor into metal bore)
⚠️This is a non-flush sensor. The sensing face must not sink inside metal mounting holes. Sinking will cause severe sensing-range loss, false triggering or failure to detect targets.
2.1 أبعاد (وحدة: مم)
خيط: M18×1
Overall length: 66 mm
Status LED at M12 plug root, 360° viewable; LED illuminates when metal target is detected
Lock nut across-flats: 24 mm
2.2 Mounting Torque
Lock-nut tightening torque: 15-20 ن · م, maximum 25 N·m. Exceeding will cause thread stripping or housing cracking.
2.3 Multi-sensor Spacing
Center-to-center distance between identical sensors ≥36 mm to avoid crosstalk false switching
Minimum clearance between sensor sidewall and nearby metal wall ≥18 mm; metal must not hug sensor body
Reference target: 18×18 mm steel plate; smaller actual targets reduce effective sensing range.
2.4 Working Gap to Target
Recommended operating gap: 4-12 mm; maximum reliable operating gap ≤14 mm; avoid continuous operation at the 16 mm limit threshold.
Sensing face shall face metal target as perpendicular as possible; tilt angle preferably <15°. Larger tilt reduces effective sensing distance.

❗Use M12-A-coded 3-core female-end cables. Standard 4-core M12 cables are also acceptable, leave pin 2 unconnected.
Built-in Electrical Protections
Reverse-polarity protection, output short-circuit protection, حماية الزائد.
PLC connection: Connect to PNP-type digital input module.
الأحمال الحثية (relay coils): Fit free-wheeling diode in reverse parallel across coil terminals.
الأحمال المقاومة: Keep load current ≤200 mA.
العمليات المحظورة
- Do NOT apply AC voltage; only 10-30 VDC DC supply permitted.
- Route sensor cables separately from high-power power cables to minimize electromagnetic interference.
- Power-on Commissioning Procedure
- Complete all wiring; verify no short-circuits before applying power.
- No metal target present: LED OFF.
- Move steel target toward sensing face: LED turns ON within sensing range; LED turns OFF after removing target.
- Cycle target repeatedly: confirm stable ON/OFF without flickering.
This sensor has no sensitivity potentiometer. Sensing distance cannot be adjusted electronically; adjust mechanical gap only.
- Environmental Operating Conditions
- IP68 rating permits temporary water immersion; fully tighten M12 connector, poor sealing degrades IP rating.
- Operating temperature -40℃～+85℃; select low-temperature-rated cables for cold environments.
- Avoid heavy impact to PBT sensing face; prevent welding-spatter exposure.
- استكشاف الأخطاء وإصلاحها
| أعراض | Check Items |
| LED never lights | Check 10‑30VDC supply, brown/blue wiring, fully‑seated M12 plug |
| LED always ON without target | 1. Sensor sunken into metal bore (most common fault); 2. Nearby metal too close to sensor body; 3. Insufficient inter‑sensor spacing; 4. Output short‑circuit |
| Intermittent flickering when target arrives | Operating gap near 16 mm limit; nearby metal interference; EMI from power cables; undersized target |
| LED OFF even with target present | خطأ في الأسلاك; excessive target gap; non‑ferrous target (Al/Cu reduce sensing performance) |

- Minimum gap between sensor side and metal wall: ≥18 mm.
- Suggested working gap: 4-12 mm; avoid continuous operation near 14-16 mm threshold.
- Keep target perpendicular to sensing-face; tilt angle＜15°, sensing distance drops with larger tilt.

ملاحظات هامة
- Non-flush-type sensor: sensing face must protrude from metal mounting surface. Sinking causes range degradation, false-switching or no detection.
- DC-only device, AC input forbidden.
- Fit reverse-parallel free-wheeling diode for inductive loads e.g. relay coils.
- Separate sensor signal cables from high-power power cables to reduce EMI.
Quick Troubleshooting Summary
LED permanently ON without target: Likely sunken installation, nearby metal interference or insufficient inter-sensor distance.
Flickering upon detection: Working gap close to 16 mm maximum limit; reduce mechanical gap.
LED never illuminates: Verify supply voltage, M12 connector seating and brown-blue power wiring.
