Pro-Range XKC-KL200-NPN-DC 5-24V Laser Ranging Sensor, 4m Sensing Distance, NPN Output

The sensor provides two outputs: a digital NPN open-collector output and a UART serial interface. For the NPN output, connect the black wire (output) to your load, the blue wire to ground (GND), and the brown wire to a positive supply voltage between 5V and 24V DC. The UART interface uses specific wires (typically yellow for TX, white for RX) for communicating distance data at TTL logic levels.

The sensor features onboard buttons that allow you to configure the sensing window, output delay, and other parameters directly without a PC. Refer to the product manual for the specific button-press sequences to enter the configuration mode and adjust settings like the maximum detection distance or the hysteresis band.

While the sensor has a multi-layer filter cover designed for strong anti-interference ability, extreme direct sunlight or highly reflective environments may affect performance. It is primarily designed for indoor or controlled outdoor industrial applications. For harsh outdoor conditions, additional environmental shielding may be necessary.

The NPN output acts as a simple digital switch, turning on (sinking current) when an object is within the configured sensing zone. The UART interface provides continuous, precise distance data in numerical form (e.g., in millimeters), allowing for more complex logic and integration with microcontrollers or PCs for advanced applications like mapping or precise positioning.
