ua18cld06ag – ult prox lp m18 diff analogue 4-20ma cab

Why Choose the Carlo Gavazzi UA18CLD06AG Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD06AG is an industrial M18 ultrasonic proximity sensor with a 4–20 mA analogue output, designed for non-contact distance and level measurement in automation and process applications. Using diffuse-reflective ultrasonic sensing, it can detect a broad range of target materials without relying on their colour, transparency or surface finish.

As part of Carlo Gavazzi’s UA18CL series, the UA18CLD06AG combines an integrated amplifier, adjustable sensing range and robust plastic cylindrical housing. Its analogue current output provides a proportional signal that can be connected to PLC analogue inputs, controllers and monitoring equipment for continuous measurement rather than simple on/off detection.

The sensor provides an adjustable sensing distance of 100–600 mm, operates from an 18–30 V DC supply and is supplied with a 2 m cable. With an IP67 enclosure and an operating temperature range of -15°C to +70°C, it is suited to demanding factory automation, material handling and machine-building environments.

Reliable Non-Contact Distance Measurement

Ultrasonic sensors determine distance by transmitting high-frequency sound pulses towards a target and measuring the returning echo. This enables dependable detection of objects that may be difficult to sense using conventional optical technologies, including transparent, reflective, dark or irregularly shaped materials.

The UA18CLD06AG converts measured target distance into a standard 4–20 mA analogue signal, allowing continuous position, level or distance information to be processed by industrial controllers. Its compact M18 body makes it particularly useful where installation space is limited but continuous analogue feedback is required.

Typical Applications

• Continuous distance measurement in automated machinery.
• Tank, hopper and container level monitoring.
• Material handling and conveyor systems.
• Object position and presence measurement.
• Packaging and production machinery.
• PLC-based process monitoring and control systems.
