UB300-18GM40 Non-contact Detection ultrasonic proximity switch sensor for industrial automation

The UB300-18GM40 is a high-performance ultrasonic proximity switch, featuring an M18 cylindrical design, with a detection range of 30-300mm and a blind zone of 0-30mm. It is suitable for non-contact detection of solids, liquids, powders, and transparent objects. Its core advantages include: built-in temperature compensation to ensure stable output in environments ranging from -25°C to 70°C; support for TEACH-IN programming function for quick setting of detection upper and lower limits; response delay of approximately 30ms, repeatability ±0.5% of full scale, and resolution of 0.4mm. The device is equipped with 4-20mA analog output, short-circuit/overload protection, IP67 protection rating, and resistance to dust and oil interference. The indicator light system (yellow/red/green) provides real-time feedback on power, detection, and fault status, facilitating maintenance. It is widely used in harsh industrial environments such as metallurgy, logistics, and packaging machinery.
