- Matriz de solução de problemas para falhas comuns
| Fenômeno de falha | Causa raiz | Soluções passo a passo |
| Indicator off and no output after power-on | 1. Polaridade de energia reversa | 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 (preto puro / 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 | |
| Falso acionamento & 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. Interferência eletromagnética severa | 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 |

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.
- Definição de fiação & Connection Instructions
9.1 Standard Cable Version (Suffix -E2, 2m PVC Cable, 3-arame)
| Cor do fio | Função | Descrição |
| Marrom | Poder Positivo (V+) | Connect to 10~30VDC positive terminal |
| Azul | Potência Negativa (GND) | Connect to power 0V / negative terminal |
| Preto | Saída de sinal (FORA) | NPN normalmente aberto (NÃO) saída |
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).
Fiação Típica (Connect to PLC Sinking Input)
Brown wire → 24V+ of switching power supply
Blue wire → 0V of switching power supply & PLC common terminal (COM)
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. Para cargas indutivas, connect a freewheeling diode in reverse parallel.
9.3 M12 Connector Version (Suffix -C, 4-pin Male Connector)
Atribuição de pinos (View from sensing face, numbered clockwise):
- Alfinete 1: Marrom (Poder +)
- Alfinete 3: Azul (Poder -)
- Alfinete 4: Preto (Saída de sinal)
- Alfinete 2: Poupar (Não utilizado)
- Montagem & Precauções com fiação
- 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. Não conduza cargas de alta potência diretamente; use intermediate relays for transition.
- Requisitos Ambientais: 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 (inversor, servo cables) with a distance of ≥20cm. Do not lay them in the same conduit.
