ua18cld15no – ult prox lp m18 diff npn no cable
Carlo Gavazzi UA18CLD15NO is an M18 diffuse-reflective ultrasonic proximity sensor with an adjustable 200-1500 mm sensing distance, NPN normally-open output, 8 Hz operating frequency, 18-30 V DC supply, 2 m cable and IP67 protection.
Why Choose the Carlo Gavazzi UA18CLD15NO Ultrasonic Sensor?
The Carlo Gavazzi UA18CLD15NO is an industrial diffuse-reflective ultrasonic proximity sensor designed for reliable non-contact object detection across automation, material-handling and machine-building applications. Part of the Carlo Gavazzi UA18CLD series, it combines an M18 cylindrical plastic housing with an NPN normally-open switching output.
The UA18CLD15NO provides an adjustable sensing distance of 200–1500 mm, extending detection capability to applications requiring greater working distances than shorter-range M18 ultrasonic sensors. Its NPN normally-open output provides a straightforward discrete switching signal for compatible PLC, controller and machine-control inputs.
Designed for industrial environments, the sensor operates from an 18–30 V DC supply and features an integral 2 m cable, compact M18 × 89 mm PBT housing and IP67 protection rating. An operating frequency of 8 Hz, yellow LED indication and integrated electrical protection support dependable operation in automated equipment.

Medium-Range Ultrasonic Object Detection
Ultrasonic sensors detect objects by transmitting high-frequency acoustic pulses and evaluating the returning echo. Because detection is based on sound rather than visible light, ultrasonic technology can detect many targets regardless of colour, transparency or optical surface characteristics, making it useful where photoelectric detection can be more challenging.
The Carlo Gavazzi UA18CLD15NO combines an adjustable 200–1500 mm sensing range with an NPN normally-open switching output. When a target meets the configured detection condition, the sensor provides a discrete transistor signal to compatible industrial control equipment, making it suitable for object presence, position and level-detection tasks.
Typical Applications
- Object presence and position detection.
- Packaging and production machinery.
- Conveyor and material-handling systems.
- Container and product detection.
- Liquid and bulk-material level detection.
- Automated assembly equipment.
- Factory automation systems.
- Machine-building applications requiring medium-range non-contact detection.
