Cylindrical ultrasonic transducer TA0300KC

high-frequencyproximitymeasurement

Product Overview
The TA0300KC is a compact 300 kHz ultrasonic transducer designed for precise short-distance measurement and small-blind-zone ultrasonic sensing in gas media. Its ultra-small Φ10 × 7 mm PBT housing and contact-pin interface enable integration into constrained inspection modules, paper-handling equipment and compact automation systems.

Key Features

• Short-distance accurate measurement: Optimized for close-range detection with a minimal blind zone and high repeatability.
• 300 kHz center frequency: Operates at 300 kHz ±4% for high-frequency ultrasonic detection.
• Small blind zone: Suited to applications requiring measurements very near the sensor face.
• Fast aftershock time: Aftershock (ring-down) time <180μs, supporting rapid short-distance sampling.
• Compact Φ10 × 7 mm housing: Very small mechanical size for easy integration into limited spaces.
• PBT case material: Durable thermoplastic housing for compact sensor assemblies.
• Contact pin interface: Φ0.6 × 10 contact-pin weld connection for PCB or embedded mounting.

Mechanical Design
The TA0300KC uses an ultra-compact Φ10 × 7 mm PBT enclosure and weighs approximately 1 g. The Φ0.6 × 10 contact-pin weld interface is specified for minimal cable length and straightforward PCB or embedded integration, making the transducer suitable for tight mechanical layouts and compact ultrasonic modules.

Electrical and Test Information
Electrical specifications include admittance curve, sensitivity test and aftershock time data. Reference sensitivity condition: 0 dB = 20 Vp-p at 50 mm with 40 dB gain; typical output >1.0 V. Aftershock time <180 μs supports reliable short-distance detection and small blind-zone performance.

Why Choose the TA0300KC
The TA0300KC is a purpose-built 300 kHz ultrasonic transducer for engineers requiring precise short-distance sensing in compact systems. Its small beam angle (9°), fast ring-down, tiny Φ10 × 7 mm footprint and contact-pin format simplify integration into paper-handling, inspection and compact automation applications.
