This system is a flow measurement system that visualizes the wind speed distribution of airflow in real-time on-site by having LED indicators on wind sensor units arranged at multiple points light up in colors corresponding to the wind speed. It can connect up to 4,500 wind sensor units, allowing for simultaneous wind speed measurements, making it possible to measure the wind speed distribution in two-dimensional or three-dimensional formats. Additionally, the method of connecting wind sensor units in a daisy chain along with a compact control box allows for installation in minimal time and space. 【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.

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 the 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 is compliant 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.

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 create 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-processes such as chip mounting, component mounting, wire bonding, resin sealing, and ball mounting using our in-house component mounting line, according to your needs. *For more details, please refer to the PDF document or feel free to contact us.
