| ظاهرة الخلل | السبب الجذري | Step-by-Step Solutions |
| Indicator off and no output after power-on | 1. Reverse power polarity | 1. Check brown and blue wires and rewire correctly |
| 2. Supply voltage out of 10~30VDC range | 2. Measure supply voltage with multimeter to ensure it is within rated range | |
| 3. Internal cable breakage | 3. Replace cable or conduct cross test with spare sensor | |
| No signal output even when object is detected | 1. Object beyond effective sensing distance | 1. Reduce the distance between sensor and object with proper margin |
| 2. Low reflectivity of measured object (pure black / light-absorbing material) | 2. Use high-reflective surface or select 40cm long-distance model | |
| 3. Wrong wiring of output circuit | 3. Verify complete connection of black output wire and load circuit | |
| False triggering & continuous output with no object | 1. Highly reflective objects in background | 1. Adjust mounting angle to avoid reflective background |
| 2. Strong ambient light directly irradiating the receiver lens | 2. Install light shield to block strong direct light | |
| 3. Severe electromagnetic interference | 3. Route sensor cables away from power cables and ensure proper grounding | |
| Fluctuating and unstable output signal | 1. Object stays at the detection boundary | 1. Fine-tune mounting distance to stay away from critical zone |
| 2. Dust or dirt covering the lens | 2. Clean the lens with a soft dry cloth |

- Detailed Mounting Dimensions
This sensor adopts threaded cylindrical mounting. Dimensions and mounting regulations are specified as follows:
| غرض | مواصفة |
| Main Thread | M18 × 1mm (Metric fine thread) |
| Effective Thread Length | 30مم |
| Sensor Body Length (Excluding cable/connector) | تقريبا. 53.5مم (cable version) |

Mounting Instructions
- Fix the sensor on cabinet panels, brackets and other mounting positions via two lock nuts; the extension length is adjustable.
- Align the sensing face towards the moving direction of measured objects. The tilt angle is recommended ≤15°, otherwise the effective sensing distance will be reduced.
- This is a non-flush mount sensor. Do not embed the sensing face into metal mounting surface; keep the sensing face fully exposed.
- Wiring Definition & Connection Instructions
9.1 Standard Cable Version (Suffix -E2, 2m PVC Cable, 3-wire)
| Wire Color | وظيفة | وصف |
| بني | Power Positive (الخامس+) | Connect to 10~30VDC positive terminal |
| أزرق | Power Negative (أرض) | Connect to power 0V / negative terminal |
| أسود | إخراج الإشارة (OUT) | NPN Normally Open (لا) الإخراج |
9.2 Wiring Principle of NPN NO Output
This model is NPN sinking output:
When no object is detected: Output terminal is floating, internal transistor cuts off with no signal output.
When object is detected: Internal transistor turns on, black output wire connects to blue power negative terminal and outputs low level (0V).
Typical Wiring (Connect to PLC Sinking Input)
Brown wire → 24V+ of switching power supply
Blue wire → 0V of switching power supply & PLC common terminal (كوم)
Black wire → PLC digital input terminal
Wiring for Relay / Indicator Load
One end of load connects to 24V+, the other end connects to sensor black output wire.
Sensor blue wire connects to 24V-.
Single-channel load current shall not exceed 300mA. للأحمال الحثية, connect a freewheeling diode in reverse parallel.
9.3 M12 Connector Version (Suffix -C, 4-pin Male Connector)
Pin assignment (View from sensing face, numbered clockwise):
- Pin 1: بني (قوة +)
- Pin 3: أزرق (قوة -)
- Pin 4: أسود (إخراج الإشارة)
- Pin 2: إضافي (غير مستخدمة)
- تصاعد & احتياطات الأسلاك
- Polarity Protection: Do not reverse power polarity. The built-in reverse polarity protection prevents burnout, but the sensor will not work normally under reversed connection.
- Load Limit: Maximum output load current is 300mA. Do not drive high-power loads directly; use intermediate relays for transition.
- المتطلبات البيئية: Avoid direct sunlight or strong LED light on the sensing window, and keep away from mirror or polished metal reflective surfaces in the background.
- EMC Requirements: Separate sensor cables from power cables (inverter, servo cables) with a distance of ≥20cm. Do not lay them in the same conduit.
