Why Choose the Carlo Gavazzi UA18CLD15AGM1 Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD15AGM1 is a compact M18 diffuse-reflective ultrasonic proximity sensor with a 4–20 mA analogue output, designed for continuous non-contact distance and level measurement in industrial automation applications. As part of the Carlo Gavazzi UA18CL series, it provides reliable measurement of many different target materials without depending on their colour, transparency or surface appearance.

The UA18CLD15AGM1 provides an adjustable 200–1500 mm sensing distance and converts the measured target position into a standard industrial 4–20 mA current signal. This proportional analogue output makes the sensor suitable for connection to PLC analogue inputs, process controllers and monitoring systems where continuous distance or level information is required.

Operating from an 18–30 V DC supply, the sensor combines a robust PBTP cylindrical housing with an IP67 protection rating for dependable industrial use. Its M12 connector provides convenient plug-in installation, while the compact M18 format enables straightforward integration into machinery, conveyors and automated production equipment.

Reliable Ultrasonic Measurement for Industrial Automation

Ultrasonic sensors determine distance by transmitting high-frequency sound towards a target and evaluating the returning echo. Because measurement is based on sound rather than visible light, ultrasonic sensing is particularly useful for transparent, reflective, dark or visually inconsistent objects that can be difficult to detect reliably with conventional optical sensors.

The UA18CLD15AGM1 converts the measured distance into a standard 4–20 mA analogue signal, enabling PLCs and industrial controllers to continuously monitor target position or material level. Its extended sensing range, compact M18 construction and plug-in connection make it a practical solution for machine builders and automation engineers requiring continuous non-contact measurement.

Typical Applications

• Continuous distance measurement in automated machinery.
• Tank, hopper and container level monitoring.
• Object positioning and presence measurement.
• Conveyor and material handling systems.
• Packaging and production machinery.
• PLC-based analogue measurement and process monitoring.
• Machine building and factory automation systems.
