Cylindrical ultrasonic transducer TA0040KC

non-contactfor level measurementproximity

Product Overview
The TA0040KC 40 kHz ultrasonic transducer is designed for middle-distance non-contact measurement applications with a detection range of 0.35–10 m and a blind zone of less than 0.35 m. It is suitable for position location, approach measurement, traffic detection, obstacle avoidance, level and distance measurement, and industrial distance detection systems.

Key Features

• 0.35–10 m measurement range: Middle-distance ultrasonic detection for industrial sensing and distance measurement.
• 40 kHz frequency: 40 kHz ±2.0 kHz center resonant frequency for stable non-contact sensing.
• 12° beam angle: 12° ±2° full beam angle for focused detection.
• Low blind zone: Blind zone <0.35 m for reliable detection beyond the minimum range.
• IP65 protection: Dust- and splash-resistant housing suitable for industrial environments.
• Screw-fixed installation: M20 × 1.5 screw structure for secure mounting.
• Customizable cable: Supplied with 3 m cable; length can be customized.
