Wiring Diagram for TL-Q5MC1-Z (NPN 아니요)

Wiring rule: 갈색 = 긍정적, 파란색 = 부정적, Black = Signal

갈색: DC+ 24V

파란색: DC0V

검은색: NPN 출력 (when iron approaches → black wire pulled to 0V, indicator ON)

This is non-shielded type. Side and rear surfaces cannot be close to metal to avoid false trigger.

1) Drive intermediate relay (independent load test)

Brown → 24V+

Blue → 24V-

Black → One terminal of relay coil

The other terminal of relay coil → 24V+

✅ Iron detected: Relay energized; No iron: Relay de-energized

2) Mitsubishi FX (sink input, 가장 일반적인)

갈색: 24V+

파란색: 0다섯

검은색: X0 (X input terminal)

PLC COM terminal: Connect to 24V+

싱크 입력: X point detects 0V signal → input LED ON, matching NPN output

3) Siemens S7-200SMART / S7-1200 (DI sink wiring)

갈색: 24V+

파란색: 0다섯

검은색: I0.0 (DI terminal)

Input common terminal 1M: Connect to 24V+

메모: Siemens DI supports sink/source switching. NPN sensor requires 1M connected to +24V. If 1M is connected to 0V, it is for PNP sensors, this model cannot work.

4) 오므론 CP1E/CP1H

갈색: 24V+

파란색: 0다섯

검은색: Input terminal (예를 들어. 0.00)

COM: Connect to 24V+

⚠️ 중요: Sensor power supply and PLC power supply must share the same GND (0V connected together), otherwise signal jitter and unstable detection.

1. Quick Multimeter Test Method (Test before power-on to avoid damage)
2. 배선: Brown to 24V+, Blue to 0V, black wire open-circuit
3. No iron nearby: Voltage on black wire ≈ 24V, indicator OFF
4. Iron block close to front face (≤4mm): Voltage on black wire ≈ 0V, indicator ON
5. Iron removed: Back to 24V, indicator OFF

If the performance is inconsistent → sensor damaged or wiring error

III. Troubleshooting List for TL-Q5MC1-Z

1. 설치 & 배선사양 (Non-shielded Priority)
2. 감지거리: Practical working distance ≤4mm, avoid using the 5mm limit
3. Mounting clearance: Keep ≥15mm clearance between sensor side/rear and metal. Shielded type can be flush mounted.
4. Multi-sensor side-by-side installation: Center distance ≥30mm between two TL-Q sensors to prevent mutual interference
5. 케이블: Standard 2m; If extended, 차폐 케이블을 권장합니다, shield grounded at single end; Do not run together with inverter / servo power cables
6. Minimum iron target: Iron plate ≥17×17×1mm. Small workpiece causes unstable detection.
7. Emergency Conversion Solution

If PLC only supports source input (COM connected to 0V) and only TL-Q5MC1-Z (NPN) 사용 가능:

Use the NPN output to drive a DC24V miniature relay, then feed the relay dry contact to PLC input for signal isolation conversion.

Typical Application Cases of TL-Q5MC1-Z (NPN 아니요, 비차폐, 5mm)

Core constraints: Only detect ferromagnetic metal; reserve clearance from surrounding metal for non-shielded type; response frequency 500Hz; NPN 아니요, signal ON when metal approaches

사례 1: Workpiece arrival detection on conveyor line (가장 널리 사용되는)

Scene: 벨트 컨베이어, tooling pallet assembly line, confirm iron/stainless steel workpiece arrives at station

해결책: Sensor mounted at side of station, small iron sheet installed on pallet as target. When pallet arrives and iron sheet enters 0–4mm sensing zone, NPN signal sent to PLC input

논리: Signal ON → stop conveyor, start clamping / machining / 마킹; Signal OFF → release

메모:

Keep ≥15mm gap between conveyor frame metal and sensor side to avoid false trigger

알류미늄 / copper workpiece cannot be directly detected, add iron target plate

호환 PLC: Mitsubishi FX, Siemens S7-200SMART (sink input)

사례 2: 기원 & hard limit for machine slide / 속이는 사람

Scene: Small CNC equipment, servo slide, transfer manipulator origin homing and overtravel protection

해결책: Iron target plate fixed on slide side, sensor installed at origin position. When slide returns home, 트리거 신호, PLC reset position and confirm origin completion. A second sensor can be used as overtravel limit.

이점: 비접촉, 기계적 마모 없음, better durability than mechanical limit switch under oil and iron chip environment

Risk reminder: Non-shielded type cannot attach to machine sheet metal, use bracket for floating installation. Iron chips accumulated on sensing surface will cause continuous false trigger, regular blow cleaning required.

사례 3: Gear / rotary table speed detection & pulse measurement

Scene: Indexing table, motor driven gear, rotary fixture, speed measurement, stall detection, 동기 제어

해결책: Ferromagnetic gear teeth aligned to sensor, pulse output when teeth pass by. PLC high-speed counter collects pulses to calculate rotation speed and stall status.

Upper limit: 맥스. 500헤르츠, suitable for low-speed rotary table (low RPM), not for high-speed spindle

시운전: Gap between tooth top and sensor controlled at 2–3mm; tooth width cannot be too small to guarantee stable pulse.

사례 4: Counting screws, nuts and stamping small parts

Scene: Vibratory feeder discharge, stamping blanking, hardware assembly machine, count ferrous parts

해결책: Sensor mounted beside vibratory feeder track, trigger one pulse when screw passes sensing zone. PLC accumulates count, alarm or stop machine when reaching set value.

Pain point: Repeated triggering for fast passing small parts; add debounce delay / single pulse latch in PLC program

한정: Only ferrous parts; weak magnetic stainless steel has reduced sensing distance, reduce gap accordingly.

사례 5: Cylinder / clamping fixture status feedback

Scene: Pneumatic clamping mechanism, fixture cylinder, confirm jaw clamping completion

해결책: Iron target plate fixed at end of cylinder piston rod, sensor installed at cylinder tail. When cylinder extends to clamp, iron sheet approaches sensor and signal ON, PLC confirms clamping finished and allows next action.

비교: Better than cylinder magnetic switch — no risk of magnet demagnetization; 불리: Extra metal target plate needed.

사례 6: Low-level material alarm for ferrous bulk material silo

Scene: Iron powder, iron chips, steel ball silo, low material level alarm (lower limit detection)

해결책: Sensor installed at lower side wall of silo. When material level higher than sensor, metal material covers sensing surface, signal ON; when material level drops below sensor, signal OFF, PLC triggers low material alarm for feeding reminder.

한정: Only for ferromagnetic bulk material; clean sensing surface regularly under heavy dust environment.

사례 7: Metal part presence confirmation & missing part check for packaging machine

Scene: Auto parts and hardware packaging machine, confirm iron gasket / iron clip is loaded

해결책: Sensor fixed at station. When packaging is in place and target detected, 정상; no signal = missing part, trigger reject mechanism.

메모: Packaging machine frame has lots of metal, isolate sensor with bracket, cable shielding required, keep away from inverter power cables.

사례 8: 자동화창고 & turnover pallet identification

Scene: Roller conveyor pallet positioning, iron sheet pre-installed on pallet bottom for station positioning and diverting

해결책: Sensor mounted above or side of roller frame. When pallet flows to target station, iron sheet triggers signal, PLC stops roller and starts scanning or transfer action.

Multi-sensor mounting: Center distance ≥30mm between two TL-Q sensors to avoid mutual interference.
