KJT-ST series basic photoelectric switch 671/674

KJT-ST series sensor is a basic photoelectric sensor product independently developed and produced, integrating photoelectric conversion circuit, amplification circuit, logic processing circuit and drive output circuit. Compared with similar foreign products, it has the advantage of low price, fast response, high precision and stable quality. It is suitable for robots, automatic production lines, lathes, manipulators and mechanical arm components, food processing equipment, printing equipment and other industrial machinery and equipment.

Product characteristics
It directly replaces imported products of relevant models and has the following advantages:
Low energy consumption (less than 17ma);
1KHz --- 3KHz high-speed response;
Automatic pin polarity protection, wrong wiring will not damage the device itself;
2mil gold plated pin, long-term oxidation resistance, ensuring system stability
Built in amplifier and digital conversion circuit to output CMOS standard level, which is convenient for signal acquisition and can directly match with multiple loads;
The action mode, such as light time ON and dark time ON, can be switched by connecting the "L" end and the "+" end. This function can be used to easily form a small control system;
Detection distance 5mm (groove width)
Standard detection object opaque 2 × 0.8mm
Tolerance distance 0.025mm
Light source (light emission wavelength) GaAs infrared light emitting diode (940nm)
Display lamp × 1 The light is on when the light is blocked (red)
Power supply voltage DC5V -- DC24V ± 10% pulsation (p-p) below 10%
Static current consumption below 20mA (NPN type)
KJT-ST676
The indicator is on when the control output is illuminated, and the NPN collector has no output; The indicator is off when the light is blocked, and the open circuit output of NPN collector is DC5V -- 24V, less than 100mA, the residual voltage is less than 0.5V (when the load current is 100mA), and the residual voltage is less than 0.3V (when the load current is 40mA)

KJT-ST676
The indicator will not go off when the control output is illuminated, and the NPN collector has no output; The indicator light is on when the light is blocked, and the open circuit output of NPN collector is DC5V -- 24V, below 100mA, the residual voltage is below 0.5V (when the load current is 100mA), and the residual voltage is below 0.3V (when the load current is 40mA)

Automatic protection Built in polarity automatic protection circuit, the sensor itself will not be damaged when the lead is connected incorrectly, but it will not work
