Why Choose the Carlo Gavazzi UA18CAD09NGTI Ultrasonic Sensor?

The Carlo Gavazzi UA18CAD09NGTI is a versatile diffuse-reflective ultrasonic proximity sensor designed for non-contact distance measurement, object detection and level monitoring in industrial automation applications. As part of the Carlo Gavazzi UA18CAD ultrasonic sensor series, it combines an M18 cylindrical PBT housing with both analogue and digital outputs for flexible integration into PLC-controlled machinery and process systems.

The UA18CAD09NGTI provides a rated sensing range of 100–900 mm with a blind zone of up to 100 mm. It combines a 4–20 mA analogue output with an NPN digital switching output, allowing continuous proportional distance measurement and discrete switching from a single sensor. Integrated Teach-in functionality simplifies configuration for the required detection or measurement task.

Designed for industrial control systems, the sensor operates from a 15–30 V DC supply and features an integral 2 m cable, robust M18 PBT housing and IP67 protection rating. With an operating frequency of up to 4 Hz, the UA18CAD09NGTI is particularly suited to distance, level, diameter and loop-control applications requiring dependable non-contact measurement.

Flexible Ultrasonic Measurement and Object Detection

Ultrasonic sensors determine distance by transmitting high-frequency acoustic pulses and evaluating the returning echo from a target. Because measurement is based on sound rather than visible light, ultrasonic technology can detect many objects independently of colour, transparency or optical surface characteristics, making it useful for applications where conventional photoelectric detection may be less suitable.

The Carlo Gavazzi UA18CAD series combines compact M18 installation with Teach-in configuration and simultaneous analogue and digital outputs. The UA18CAD09NGTI provides a 4–20 mA proportional measurement signal together with an NPN switching output, allowing an automation controller to receive continuous distance information and a discrete switching state from a single sensor.

Typical Applications

• Industrial distance measurement.
• Liquid and bulk-material level monitoring.
• Object presence and position detection.
• Diameter measurement and monitoring.
• Loop-control applications.
• Packaging and production machinery.
• Conveyor and material handling systems.
• Automated assembly and manufacturing equipment.
