HYDZ HY40A12R09-1 40kHz Ultrasonic Receiver Plugin, 12x9mm Open Receiver

The HY40A12R09-1 is tuned to a resonant frequency of 40kHz with a sensitivity of -65dB. This makes it specifically designed to detect ultrasonic pulses at 40kHz, which is a common frequency for distance measurement and object detection systems, ensuring optimal signal reception when paired with a matching transmitter.

This is an open, plugin-style receiver element with solderable pins or plugin terminals. It is designed for direct integration onto a custom PCB. You must provide appropriate signal conditioning circuitry (such as an amplifier and filter) on your board to process the weak piezoelectric signal generated by the receiver upon detecting ultrasonic waves.

The receiver is rated for operation from -25°C to +60°C. This range allows for reliable performance in both indoor climate-controlled environments and more demanding industrial or outdoor settings where temperature fluctuations may occur.

This is a receiver-only component. To create a functional ultrasonic sensing system (like for distance measurement), you must pair it with a separate 40kHz ultrasonic transmitter. The system works by emitting a pulse from the transmitter and timing the echo received by this component.
