Why Choose the Carlo Gavazzi UA18CLD05AGTR Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD05AGTR is a compact ultrasonic diffuse-reflective proximity sensor with 4–20 mA analogue output designed for non-contact distance, position and level detection in industrial automation applications. Its ultrasonic sensing principle allows reliable detection of many objects and materials without depending on their colour, transparency or optical contrast.

The UA18CLD05AGTR features an M18 cylindrical PBTP housing and a rated sensing range of 60–500 mm. The sensor provides an adjustable analogue output characteristic, allowing the 4–20 mA output slope to be configured as positive or negative using the remote teach-in function. This makes it suitable for applications requiring a proportional analogue signal corresponding to target distance.

With a 2 m cable connection, compact M18 × 93 mm body and IP67 protection, the UA18CLD05AGTR is designed for straightforward integration into industrial machinery. Protection against short circuits, reverse polarity and electrical transients further supports dependable operation in demanding automation environments.

Reliable Non-Contact Distance and Level Detection

Ultrasonic sensors such as the Carlo Gavazzi UA18CLD05AGTR transmit high-frequency sound waves towards a target and evaluate the returning echo to determine its distance from the sensor. Because detection is based on reflected sound rather than visible light, ultrasonic technology can be particularly useful for sensing objects where colour, surface appearance or transparency makes optical detection difficult.

The UA18CLD05AGTR converts the measured target position into a proportional 4–20 mA analogue signal. Remote teach-in allows the required measuring points to be configured for the application, while the selectable positive or negative output slope enables the analogue signal to increase or decrease with target distance as required by the connected control system.

Typical Applications

• Non-contact distance measurement.
• Tank, hopper and container level monitoring.
• Industrial machinery and automation systems.
• Object position and presence detection.
• Conveyor and material handling equipment.
• Packaging and processing machinery.
• PLC analogue measurement applications.
• OEM machines requiring proportional distance feedback.
