KJT slot-type photoelectric switch is actually a kind of through-beam photoelectric switch, also called U-shaped photoelectric switch. It is an infrared sensing photoelectric product, which is composed of an infrared transmitter tube and an infrared receiver tube. The slot width is It determines the strength of the induction receiving model and the distance of the received signal. Light is used as the medium, and the infrared light between the luminous body and the light receiving body is received and converted to detect the position of the object. The trough photoelectric switch is also non-contact like the proximity switch. It is less restricted by the detection object and has a long detection distance. It can detect long distances (tens of meters) with high detection accuracy and can detect small objects. The application is very wide.
Sensing distance(all series) | 5mm (slot width) |
Standard detection object | Opaque object 2x0.8mm |
The difference distance | 0.025mm |
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 |
