주문번호: BES03RM, 전체 모델: BES M18MG-PSC16F-S04G, M18 non-flush inductive proximity sensor
- 제품개요
- 유형: Inductive proximity switch, non-flush (cannot be flush-mounted)
- 주택: M18×1 nickel-plated brass; sensing face PBT engineering plastic
- 감지거리: Nominal Sn=16 mm, effective operating distance Sr≈16 mm
- 산출: PNP NO normally-open, 3-wire DC 10-30VDC, 최대. load 200 mA
- 인터페이스: M12-A-coded 3-pin male plug (NOT 4-pin)
- 평가: IP68; Operating temperature -40℃～+85℃; Switching frequency 430 Hz
- Standard accessories: 2 pcs M18 lock nuts
- 기계적 설치 사양 (비판적인: 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 치수 (단위: mm)
실: 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 N·m, 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.
- 전기 배선 (M12-A-coded 3-pin male pin-out)
| M12 Pin No. | 와이어 색상 | 기능 |
| 1 | 갈색 | DC+ Power 10‑30V DC |
| 2 | — | 연결되지 않음, no internal wiring |
| 3 | 파란색 | 0다섯 / 접지 |
| 4 | 검은색 | PNP signal output (NO Normally Open) |
❗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, 과부하 보호.
PLC connection: Connect to PNP-type digital input module.
유도 부하 (relay coils): Fit free-wheeling diode in reverse parallel across coil terminals.
저항 부하: Keep load current ≤200 mA.
금지된 작업
- 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.
- 문제 해결
| 징후 | 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 | 배선 오류; excessive target gap; non‑ferrous target (Al/Cu reduce sensing performance) |

Installation Spacing Rules
- Adjacent identical-model sensors: center-to-center ≥36 mm for anti-crosstalk.
- 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.

중요 사항
- 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.
