Cylindrical ultrasonic transducer TA0022KA

low-frequencyfor level measurementproximity

Product Overview
The TA0022KA 22kHz ultrasonic transducer is a long-range ultrasonic sensor engineered for distance and level measurement, position detection, traffic monitoring and obstacle avoidance. It provides a reliable detection range from 0.8 m to 30 m with a blind zone under 0.8 m. The unit features a 22kHz ±2.0kHz resonant frequency, 15° ±2° beam angle, PVC-sealed housing, G1 threaded installation and IP65 protection, suitable for industrial and outdoor installations.

Key Features

• Long-range detection: 0.8 m to 30 m measurement capability.
• 22kHz operating frequency: optimized for medium-to-long-range sensing.
• Narrow beam: 15° ±2° beam angle for focused directional detection.
• PVC-sealed housing: durable outer shell for industrial environments.
• G1 threaded mounting: simple fixed installation on panels or fixtures.
• IP65-rated: dust-tight and protected against low-pressure water jets.
• Custom cable length: standard 3 m cable, configurable on request.
