HYDZ HY40A16T12-1 40kHz Ultrasonic Open Transmitter 16x12mm

The HY40A16T12-1 is designed to operate at a center frequency of 40kHz. This frequency is optimal for air-coupled ultrasonic applications like distance measurement and object detection, providing a balance between resolution, range, and atmospheric absorption.

This is a component-level product. The HY40A16T12-1 is an open, un-housed piezoelectric transmitter element. It requires external driving circuitry (like a pulse generator) to function and must be paired with a separate ultrasonic receiver and timing electronics to create a complete distance-measuring system.

The -62dB sensitivity rating indicates the transmitter's efficiency in converting electrical input power into acoustic output power. A higher negative dB value (closer to 0) typically represents a more efficient transducer. This rating helps in designing the appropriate drive amplifier for your system.

The provided datasheet specifies a voltage rating of 140V. This likely refers to the maximum drive voltage or insulation rating for the piezoelectric element. Always consult the official datasheet for precise driving signal requirements (typically high-voltage, short-duration pulses) to ensure optimal performance and avoid damaging the component.
