Cylindrical ultrasonic transducer TA0040KA

non-contactfor level measurementproximity

Product Overview
The TA0040KA 40 kHz ultrasonic transducer is designed for long-distance non-contact distance measurement with a detection range of 0.4–12 m and a blind zone of less than 0.4 m. It is intended for position detection, approach sensing, traffic measurement, obstacle avoidance and industrial distance monitoring under demanding environmental conditions.

Key Features

• Detection range 0.4–12 m: long-range ultrasonic distance measurement suitable for industrial and outdoor applications.
• 40 kHz operating frequency: center resonant frequency 40 kHz ±2.0 kHz for stable measurement performance.
• 15° beam angle: 15° ±2° full beam angle for focused detection and reduced cross-talk.
• Low blind zone: blind zone < 0.4 m for reliable measurements outside the minimum range.
• IP66 protection: dust-resistant and water-tight enclosure for harsh environments.
• Screw-fixed installation: M20 × 1.5 screw structure for secure mounting.
• Customizable cable length: supplied with 2 m cable; cable length can be customized to installation needs.

Typical Applications

• Position detection
• Approach measurement
• Traffic and vehicle detection
• Obstacle avoidance
• Distance and level measurement
• Industrial automation sensing

Mechanical Design
The TA0040KA features a cylindrical housing sized Φ62 × 63 mm, made of PVC, designed for screw-fixed mounting in industrial equipment, traffic detection systems and automation devices. The device provides IP66 protection and is supplied with a standard 2 m cable; cable customization is available for different installation layouts.
