Product Details

Ultrasonic Sensor U18 NPN PNP 45Hz 200mA 30-300mm Distance Sensors


A compact, industrial-grade proximity sensor with dual NPN/PNP outputs and 30-300mm adjustable detection range. Features 45Hz response speed and IP67 protection for reliable operation in harsh environments.

Key Features

Precision Distance Sensing

  • 30–300mm Detection Range – Adjustable via potentiometer

  • ±2% Measurement Accuracy – Reliable object positioning

  • 45Hz Response Frequency – Fast detection for moving targets

Flexible Output Options

  • PNP (NO/NC) + NPN (NO/NC) – Configurable for any PLC input

  • 200mA Sink/Source Current – Directly drives relays or small loads

Industrial Durability

  • IP67 Rated Housing – Dustproof & waterproof for harsh environments

  • -25°C to +70°C Operation – Stable performance in extreme conditions

  • ABS Plastic + Metal Thread – Vibration & impact resistant

Easy Installation & Adjustment

  • M18 Threaded Barrel (54mm Length) – Standard industrial mounting

  • LED Status Indicator – Power/Output visual feedback

  • Teach-in Function – Quick calibration via button
