KJT photoelectric speed sensor is a multi-functional photoelectric speed sensor product independently developed and produced. It integrates photoelectric conversion circuit, amplification circuit, logic processing circuit and drive output circuit. Compared with similar foreign products, it has the advantages of more functions and low price. Compared with similar domestic products, it has the characteristics of fast response, high precision and stable quality. Suitable for robots, automated production lines, lathes, manipulators and robotic arm components, food processing equipment, printing equipment and other industrial machinery and equipment.
Directly replaces imported products of related models and has the following advantages:
■Low energy consumption (less than 15ma);
■1KHz---3KHz high-speed response;
■Automatic pin polarity protection, wiring errors will not damage the device itself;
■Pure copper silver-plated leads, long-term oxidation resistance, effectively ensuring system stability;
■Automatic load detection function, automatic protection and yellow light indication in case of short circuit or overload;
■Built-in amplifier and digital conversion circuit, unified output CMOS standard level, convenient signal collection, can be directly matched with a variety of loads;
■Action modes such as light-ON and light-shielding ON can be switched by connecting the "L" terminal and the "+" terminal. This function can be used to easily form a small control system;
| Product Paramenters | |
| Detection distance | 5mm (groove width) |
| Standard detection object | Opaque body 2×0.8mm |
| Should be different distance | 0.025mm |
| Light source (luminescence wavelength) | GaAs infrared light-emitting diode (940nm) |
| Display light*1 | The light is on (red) when the light is blocked |
| voltage | DC5V--DC24V±10% pulsation (p-p) less than 10% |
| Quiescent current consumption | 20mA or less (NPN type) |
| KJT-CT671-YX control output | When receiving light, the red indicator light goes out, and the NPN collector has no output; when it is blocked, the red indicator light lights up, and the NPN collector open circuit output is DC5V--24V, below 100mA, and 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 100mA). When the load current is 40mA) |
| Automatic protection\alert | 1. The power polarity is automatically protected and the sensor will not be damaged if the wiring is wrong; 2. Load detection and protection. When the load is short-circuited or the impedance is too low, the output current will be automatically turned off and a yellow light warning will be issued. |
