HYDZ HY25P16T12-1 25kHz Open Transmitter 16x12mm Ultrasonic Sensor

The HY25P16T12-1 is a piezoelectric ultrasonic transmitter. It converts an applied electrical signal (typically a high-voltage pulse) into mechanical vibrations at its resonant frequency of 25kHz, generating ultrasonic sound waves. It is designed to transmit, not receive, these acoustic waves for ranging or detection purposes.

The transmitter is rated for a maximum voltage of 140V. It is crucial to use a compatible driver circuit that can provide the necessary high-voltage pulses at 25kHz without exceeding this rating to ensure optimal performance and prevent damage to the piezoelectric element.

This is a plugin-style open transmitter with exposed solder pads or pins. It requires external mounting within a suitable housing or fixture. Electrical connection is made directly to its terminals, and it must be paired with a matching receiver and appropriate signal conditioning circuitry (like a pulse generator and amplifier) to form a complete ultrasonic measurement system.
