| Standard detection object | Opaque object 2x0.8mm |
| The difference distance | 0.025mm |
| Output | NPN/PNP/NO/NC |
| Light source (luminescencewave length) | GaAs infrared light-emitting diode (940nm) |
| Indictor | The light turns on (red) when the light is blocked |
| Power supply voltage | DC5V--DC24V+10%,ripple (p-p)less than 10% |
| Static current consumption | 20mA or less (NPN type) |
| KJT-ST676 control output | When receiving light, the indicator light is on, and the NPN collector has no output.when the light isblocked, the indicator light is off, and the NPN collector open circuit outputs DC5V-24V.below 100mA, and the residual voltageis below 0.5V (when the load current is 100mA). Residual voltage 0.3V or less (whenload current is 40mA) |
| KJT-ST676 control output | The light indicator light remains on, and the NPN collector has no output; when therotor is blocked,the indicator light is on, and the NPN collector open circuit outputs DC5V--24V, below100mA, and the residual voltage is below0.5V (when the load current is 100mA). Residual voltage 0.3V or less (when the loadcurrent is 40mA) |
| Automatic protection | Built-in polarity automatic protection circuit, the sensor itself will not be damaged when connected incorrectly, but it will not work |
