Why Choose the Carlo Gavazzi UA18CLD20NPTR Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD20NPTR is an industrial diffuse-reflective ultrasonic proximity sensor designed for long-range non-contact detection in automation, material-handling and machine-building applications. Part of the Carlo Gavazzi UA18CLD series, it combines an M18 cylindrical PBTP housing with two NPN switching outputs and remote Teach-in configuration.

The UA18CLD20NPTR provides an adjustable sensing distance of 200–2000 mm and features two NPN switching outputs with configurable normally-open or normally-closed operation. Its extended detection range makes it suitable for applications such as object presence detection, position monitoring and upper/lower level control where two switching points are useful.

Designed for industrial control systems, the sensor operates from a 12–30 V DC supply and features an integral 2 m cable, compact M18 × 93 mm housing and IP67 protection rating. Remote Teach-in enables application-specific configuration while integrated short-circuit, reverse-polarity and transient protection supports dependable operation in automated machinery.

Long-Range Dual-Output Ultrasonic Detection

Ultrasonic sensors detect targets by transmitting high-frequency acoustic pulses and evaluating the returning echo. Because detection is based on sound rather than visible light, ultrasonic sensing can detect many objects regardless of colour, transparency or optical surface characteristics, making it useful for applications where photoelectric detection may be more challenging.

The Carlo Gavazzi UA18CLD20NPTR combines an adjustable 200–2000 mm sensing range with two NPN switching outputs. Remote Teach-in allows the switching parameters to be configured for the application, enabling the sensor to perform functions such as presence detection, upper and lower level monitoring or position control with two switching points.

Typical Applications

• Long-range object presence detection.
• Liquid and bulk-material level monitoring.
• Upper and lower level control.
• Packaging and production machinery.
• Conveyor and material-handling systems.
• Container and product position detection.
• Automated assembly equipment.
• Machine-building applications requiring dual switching points.
