Why Choose the Carlo Gavazzi UA18CLD06NO Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD06NO is a compact diffuse-reflective ultrasonic proximity sensor designed for reliable non-contact object detection in industrial automation and machine-building applications. Part of the Carlo Gavazzi UA18CLD series, it combines an M18 cylindrical plastic housing with an NPN normally-open transistor output for straightforward integration into industrial control systems.

The UA18CLD06NO provides an adjustable sensing distance of 100–600 mm and operates at a switching frequency of up to 25 Hz. Its NPN normally-open output provides a discrete switching signal when the configured detection condition is reached, making the sensor suitable for presence detection, position monitoring and level-control applications.

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. Integrated short-circuit, reverse-polarity and transient protection further supports dependable operation in automated machinery and production equipment.

Reliable Non-Contact Ultrasonic Object 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 independently of their colour, transparency or optical surface characteristics, making it useful where conventional photoelectric sensing may be more challenging.

The Carlo Gavazzi UA18CLD06NO combines an adjustable 100–600 mm detection range with an NPN normally-open switching output. When a target satisfies the configured detection condition, the sensor supplies a discrete transistor switching signal to compatible PLC or machine-control inputs, providing straightforward object, position and level detection.

Typical Applications

• Object presence and position detection.
• Packaging and production machinery.
• Conveyor and material handling systems.
• Container and product detection.
• Liquid and material level detection.
• Automated assembly equipment.
• Factory automation systems.
• Industrial machinery requiring an NPN normally-open proximity signal.
