Piezoelectric Application Product Group
Product Lineup
- Airborne ultrasonic sensors High frequency type
- These sensors detect the presence/absence of an object or measure the distance to the object by emitting ultrasonic waves into the air and receiving the reflected waves from the object.
The high-frequency-type sensors with a frequency of 110kHz to 400kHz are characterized by high resolution and sharp directivity.
* FUS-300A-P (white) has been updated to FUS-300A-PB (black) due to a product renewal.
- Airborne ultrasonic sensors Low frequency type
- These sensors detect the presence/absence of an object or measure the distance to the object by emitting ultrasonic waves into the air and receiving the reflected waves from the object.
The low-frequency-type sensors with a frequency of 40kHz can also be used for long-distance detection (several meters away).
* FUS-40BT and FUS-40BR (both in aluminum color) have been updated to FUS-40BT-B and FUS-40BR-B (both in black), respectively, due to a product renewal.
* FUS-40CT and FUS-40CR are currently unavailable.
- Langevin ultrasonic transducers for cleaning machines
- These ultrasonic transducers are integrated vibrators with a piezoelectric element sandwiched between two metal blocks.
Capable of high-power, high-amplitude drive, they are often used as one of the dynamic applications of ultrasonic waves.
In addition to a ready-made product lineup with frequencies of 28kHz and 40kHz for cleaning machines, FUJI CERAMICS also offers custom-made products.
- Langevin ultrasonic transducers for processing machines
- These ultrasonic transducers are integrated vibrators with a piezoelectric element sandwiched between two metal blocks.
Capable of high-power, high-amplitude drive, they are often used as one of the dynamic applications of ultrasonic waves.
These ultrasonic transducers for processing machines are used for wire bonders, plastic welders, ultrasonic cutters, etc.
In addition to ready-made products, FUJI CERAMICS also offers custom-made products.
- Humidifier transducers
- Humidifier transducers use ultrasonic vibrations generated by piezoelectric ceramics to atomize a liquid into fine particles and release them into the air.
FUJI CERAMICS provides atomizer-dedicated vibrators with high frequency, high power, and excellent durability.
- Bimorph type transducers
- Bimorph type transducers are deflection vibrators made of two piezoelectric elements bonded together, each of which can expand/contract in the length direction. In this setting, when one element expands, the other element contracts.
Depending on the wiring method, these resonators are divided into series and parallel types. They are used for actuator applications, such as micro pumps and vibration switches, and sensor applications, such as acoustic pickups.
- Ultra-sensitive air pressure sensors
- These ultra-sensitive sensors can detect slight air/gas pressure changes that were previously undetectable.
The detection range of these sensors is so broad that a single sensor can detect a slight pressure change of 1Pa up to approximately 100kPa.
- Product catalog of piezoelectric ceramics
- FUJI CERAMICS offers the elements best suited for your intended use from piezoelectric ceramics in a wide variety of material groups.
This catalog also lists piezoelectric application product, such as airborne ultrasound sensors and Langevin ultrasonic transducers. - * To download, user registration is required. Various catalogs and technical documents can be downloaded from here.
