JSUMO JS40F Digital Distance Sensor

The SUMO JS40F Digital Distance Sensor is a high-performance infrared reflective distance sensor developed specifically for compact robotic applications. It uses reflected infrared light to detect nearby objects and provides a simple digital output signal when an object is detected within its sensing range. Unlike many conventional distance sensors, the JS40F requires no external resistors, capacitors, or additional circuitry, making installation quick and straightforward. Its compact dimensions closely match the popular Sharp GP340 sensor, allowing easy integration into existing robot designs. The sensor supports operation from 3.3V to 5V , making it compatible with most microcontrollers and robot control boards. A built-in reverse polarity protection circuit helps prevent damage from incorrect wiring, while the rear-mounted LED indicator provides instant visual feedback on detection status. With its lightweight construction, low current consumption, and reliable detection performance, the JS40F is an excellent choice for mini sumo competitions, autonomous navigation, and obstacle detection systems.
