Leading Passive Type Piezo Buzzer Manufacturer

MANORSHI Electronics Co., Ltd. supplies enclosed ultrasonic sensors, which are mainly used for reversing radar, liquid level detection, proximity switch, etc. Because of its good sealing, it can be used in dust and humid environment, so it is also called waterproof ultrasonic sensor.

The transducers consist of a metal housing with the integral metal diaphragm. They operate at resonance on the first harmonic overtone. The backs of these transducers are completely sealed with resin, protecting them from exposure to the environment.
Although it is constructed to be watertight, it is not recommended for use underwater.

The enclosed structure ultrasonic sensor is a transceiver. The main diameters are 10mm, 14mm, 16mm and 25mm. The frequency is 40KHz, 48Khz, 58khz, etc.
