16mm Diameter RX TX Transmitter Receiver 20khz Ultrasonic Transducer

Description

This 20khz ultrasonic transducer is split type. There are transmitter (TX) and receiver (RX). The diameter is 16mm. In addition, we can also provide 24mm diameter 20 khz transducer.

We know that ultrasound is a mechanical wave with a frequency of 20kHz or more. Ultrasonic sensors have the dual function of transmitting and receiving sound waves. Normal housing material is silver color aluminum. If you need the black ABS plastic housing, we can customize it.

20 KHz transducer is usually the transmitter. Receiver is not in stock. If you need, you can contact us for customization. RX MOQ is 100pcs.

Characteristics of 20 khz ultrasonic transducer:

This sensor is open structure. So it can only be applicable in air medium, not in water.

High sensitivity, high reliability, high stability;

Resistant to high and low temperature, humidity, shock, vibration;

Wide range of uses: distance measurement, obstacle avoidance, anti-recording devices shielding jammer;
