KOA List of Products and Services

This system is a flow measurement system that visualizes the wind speed distribution in real-time on-site by having the LED indicators of wind speed sensor units arranged at multiple points light up in colors corresponding to the wind speed. It allows for the connection of up to 4,500 wind sensor units, enabling simultaneous wind speed measurements, which makes it possible to measure the wind speed distribution in two-dimensional or three-dimensional formats. Additionally, the system can be installed in minimal time and space due to the method of connecting the wind sensor units in a daisy chain and using a compact control box. 【Features】 ■ Visualizes the movement of airflow on-site ■ Capable of ultra-multipoint simultaneous wind speed measurement ■ Easy wiring installation *For more details, please refer to the related links or feel free to contact us.

• Wind Speed/Volume Meter

The VSM0001 is an insulated current sensor that integrates a high-current shunt from the HS series with a detection circuit. It is compact (L×W×T: 72mm×36mm×13mm) and lightweight (approximately 30g), contributing to the miniaturization and space-saving of existing sensors. It is suitable for high-precision current detection in automotive, industrial equipment, and energy sector battery management applications. 【Features】 ■ Measurement current range: ±400A (at fastening part below 75℃) ■ Detection accuracy: ±1% or less @ 25℃ ■ Low loss (detection part resistance value: 100μΩ) ■ Supports insulation between current path and output signal (using insulated amplifier) *For more details, please refer to the PDF document or feel free to contact us.

The 【RS73】 is a surface-mounted metal glaze thick film resistor. It is compatible with reflow and flow soldering, and lead-free terminal products comply with European RoHS regulations. The lead glass contained in the electrodes, resistors, and glass is exempt from European RoHS regulations. It complies with AEC-Q200 (data acquisition). We have expanded our lineup by adding the 2012 size (rated power 0.25W) and the 3216 size (rated power 0.33W). *For more details, please refer to the PDF document or feel free to contact us.

• Resistors

KLC is a substrate, package, and interposer for modules made from LTCC (Low-Temperature Co-fired Ceramic). By specifying the desired shape, size, and number of layers, it is possible to form cavities with high flatness and dimensional accuracy, making it effective as a ceramic package for mounting bare chips. In addition to applications for interposers and MEMS packages, we actively respond to small quantity demands such as prototypes for research and development and evaluation tests for semiconductor chips. Furthermore, we can accommodate post-processing such as chip mounting, component mounting, wire bonding, resin sealing, and ball mounting using our own component mounting line, depending on your needs. *For more details, please refer to the PDF document or feel free to contact us.
