Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Product Type | Capacitive Proximity Sensor (Non-contact switch) |
| Model | LJC18A3-B-Z/BX |
| Sensor Type | Capacitive proximity sensor |
| Operating Principle | Detects changes in capacitance caused by presence of materials (metal and non-metal) |
| Detection Object | Metal, non-metal materials (plastic, water, glass, oil, powder, etc.) |
| Detection Distance | 1 – 10 mm |
| Output Type | NPN, Normally Open (NO), 3-wire |
| Output Current | Up to 300 mA |
| Response Frequency | 100 Hz |
| Operating Voltage | DC 6 – 36 V |
| Wire Type | 3-wire DC (Brown = VCC, Blue = GND, Black = Output) |
