Why Choose the Carlo Gavazzi UA30CAD35NKTI Ultrasonic Sensor?

The Carlo Gavazzi UA30CAD35NKTI is an industrial M30 diffuse-reflective ultrasonic sensor combining a proportional 0–10 V DC analogue output with a configurable NPN digital switching output. Designed for non-contact distance, level and position measurement, it uses ultrasonic technology to detect a broad range of targets without relying on colour or optical contrast.

The UA30CAD35NKTI offers a wide 250–3500 mm sensing range and incorporates Teach-In configuration for setting the required sensing points. Its analogue output can be configured with a positive or negative slope, while the NPN open-collector output can operate with normally open or normally closed switching behaviour, providing considerable flexibility for machine automation and process measurement.

Built around a rugged M30 PBT housing, the UA30CAD35NKTI is the cable-connected version of this sensor configuration and is designed for direct wiring into machinery, junction boxes and control panels. Its IP67 and NEMA 4X protection, industrial temperature capability and integrated electrical protection support dependable performance in demanding installations.

Flexible Analogue and Digital Ultrasonic Measurement

The Carlo Gavazzi UA30CAD35NKTI combines continuous ultrasonic distance measurement with a discrete switching function. High-frequency sound is transmitted towards the target and the returning echo is evaluated by the sensor's electronics, allowing objects to be detected without relying on visible-light reflection. This makes the sensor particularly useful for distance, level, diameter and loop-control applications involving targets with varying colours or optical properties.

Its 0–10 V DC analogue output provides proportional distance information to a compatible PLC or controller, while the separate NPN output supplies a configurable switching signal. Teach-In functionality allows the operating points to be adapted to the application, with configurable NO / NC digital behaviour and positive or negative analogue slope providing flexible integration into automated machinery.

Typical Applications

• Non-contact distance measurement.
• Tank, hopper and container level measurement.
• Material roll and coil diameter monitoring.
• Loop and sag control applications.
• Object presence and position detection.
• Conveyor and material handling systems.
• Packaging and processing machinery.
• PLC analogue and digital input applications.
• Industrial machinery and automated production systems.
• OEM equipment requiring combined proportional and switching feedback.
