JSUMO Mz80 Infrared Sensor

The MZ80 Infrared Sensor is an infrared proximity sensor designed for non-contact object detection. It has been widely adopted in robotics projects due to its simple wiring, adjustable sensing range, and reliable performance. The sensor is housed in a durable M18 threaded cylindrical body , making it easy to mount securely in robots, automation systems, and industrial prototypes. Detection distance can be adjusted through a built-in trimmer potentiometer located on the rear side of the sensor, allowing users to fine-tune sensitivity according to application requirements. The sensor provides an NPN digital output , making it compatible with most microcontrollers, development boards, and robot controllers. It is particularly popular in sumo robot competitions , where fast and reliable opponent detection is essential. Two common wiring versions are available, differing only in wire colors while maintaining the same functionality.
