Ultrasonic Proximity Sensor, M18, NPN/PNP, NO/NC

SUCH cylindrical ultrasonic proximity sensor detects objects by emitting ultrasonic waves and measuring the reflected signal. It is ideal for applications where the target is non-metallic, irregularly shaped, transparent, or easily affected by color or surface texture. Typical uses include level detection, distance measurement, presence sensing, and automation in packaging, logistics, and material handling.

This sensor supports both NPN and PNP output types, making it compatible with various PLCs and industrial controllers. It also offers NO (normally open) and NC (normally closed) output modes, allowing users to select the appropriate switching logic based on the control system requirements. This versatility enables the sensor to be easily integrated into new or existing automation equipment.

The sensor’s cylindrical housing allows for easy mounting using standard nuts or brackets. During installation, the sensor head should face the target area with a clear and unobstructed sound path. After wiring the power and selecting the desired NPN/PNP and NO/NC configuration, users can fine-tune the sensing range or sensitivity on the sensor (if adjustable) to ensure stable detection.
