Description
25KHz ultrasonic transducer mainly has two sizes. One is 16mm diameter and the other is 24mm diamter. In addition, there are two types of sensor, namely transmitter (TX) and receiver (RX). The available material includes silver aluminum, black plastic and black aluminum. Black aluminum ultrasonic transmitter is special for shielding device.
Our 25khz transducer has high sound pressure level. It is more than 115dB. In this product, 24mm is transmitter. The max input voltage is 100 Vp-p.
Features of 25 Khz Ultrasonic Transducer:
(1) Small size, high sound pressure level, low power consumption;
(2) High sensitivity, long detection distance, high measurement accuracy;
(3) Good qualitative stability, good consistency, durability.
(4) Wide range of applications of 25khz transducer:
① Ultrasonic distance measuring system;
② Remote control devices for household appliances, toys and other electronic equipment;
③ Ultrasonic transmitter and receiver devices for anti-theft and disaster prevention equipment.
④ Repelling mosquitoes, insects, animals and other uses;
⑤ Sensors for anti-scrambler and anti-recording equipment.

Can 25khz ultrasonic waves repel mice and mosquitoes?
Ultrasonic mosquito and rodent repellent is our common electronic products. They usually use the 25khz ultrasonic transducer as the sound source. Opinions vary as to whether it actually works. Below we will provide a comprehensive and objective understanding.
(1) Technial principle of ultrasonic mosquito and rodent repellent
It is mainly the ultrasonic sensors that are at work. The sensor interferes with the pest’s nervous system by emitting sound waves of a specific frequency. These ultrasound waves will make pests feel uncomfortable. Thus make the pests leave the area covered by the device. The most common sensors are 25khz transducers.
(2) The effect is not absolute
On the one hand, ultrasound can interfere with the nervous system of pests. However, not all pests respond to ultrasound. Some pests may be amenable to ultrasonic waves. On the other hand, ultrasonic propagation is affected by environmental factors, such as temperature, humidity, and obstacles. All these factors may affect the propagation effect and coverage of ultrasonic waves. Therefore, we need to consider the technical specifications of 25khz ultrasonic transducer.
Is 25KHz ultrasonic transducer harmful to humans?
5K-15KHz is within the frequency range of sound waves. Generally, people can hear it. Being in this noisy environment can lead to irritation. So it is harmful to people. 15K-20KHz are also sound waves. But the frequency is high. Therefore, adults are not very sensitive to it. But children can still clearly hear it.
0K-25KHz belongs to ultrasonic waves. They are usually inaudible to humans and have high air loss. Ultrasonic waves with low energy are almost harmless to people. So 25khz ultrasonic transducer is not harmful.
