Why Choose the Carlo Gavazzi UA18CLD20NPM1TR Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD20NPM1TR is an industrial diffuse-reflective ultrasonic proximity sensor designed for long-range, non-contact detection in automation and machine-building applications. Part of the Carlo Gavazzi UA18CLD series, it combines an M18 cylindrical housing with two NPN switching outputs and remote Teach-in configuration.

The UA18CLD20NPM1TR provides an adjustable sensing distance of 200–2000 mm and features two NPN switching outputs with configurable NO/NC operation. This dual-output arrangement provides flexible switching-point control for applications such as object detection, level monitoring and position sensing.

Designed for industrial control systems, the sensor operates from a 12–30 V DC supply and features a compact M18 × 93 mm housing, M12 connector and IP67 protection rating. Remote Teach-in allows the switching parameters to be configured electrically, helping simplify commissioning while reducing the need for mechanical adjustment.

Long-Range Dual-Output Ultrasonic Detection

Ultrasonic sensors detect targets by transmitting high-frequency acoustic pulses and evaluating the returning echo. Because detection is based on sound rather than visible light, ultrasonic sensing can detect many objects regardless of colour, transparency or optical surface characteristics, making it useful where photoelectric sensing can be more challenging.

The Carlo Gavazzi UA18CLD20NPM1TR combines an adjustable 200–2000 mm sensing range with two NPN switching outputs. Remote Teach-in allows the switching parameters to be configured for the application, enabling the sensor to perform tasks such as object presence detection, level control and position monitoring with two configurable switching points.

Typical Applications

• Long-range object presence detection.
• Liquid and bulk-material level monitoring.
• Upper and lower level control.
• Packaging and production machinery.
• Conveyor and material-handling systems.
• Container and product position detection.
• Automated assembly equipment.
• Machine-building applications requiring dual switching points.
