K-type thermocouple wires are considered difficult to solder because solder does not adhere well to them. Incomplete soldering can lead to noise and drift, so proper work is necessary. Leveraging unique know-how gained from years of experience, skilled workers ensure reliable soldering. We achieve stable signal connections even under high-speed vibration conditions. Additionally, applying a coating to the soldered areas further enhances durability. ★★ We are currently offering a free booklet featuring "Soldering Techniques for K-type Thermocouple Wires" and more! ★★ Right now, we are also giving away the essential "Troubles and Solutions for Thermocouple Measurement of Rotating Bodies" for free! It is packed with useful information, including "Soldering Techniques for K-type Thermocouple Wires," so if you are a technician doing your own soldering, please take a look. *If you are interested, you can view the booklet by clicking the download button below. *For more details, feel free to consult or contact us.

The EMC test optical fiber transceiver is a system that converts voltage signals into optical signals and transmits them to measuring instruments. By converting to optical signals, it avoids noise interference from strong electric fields and strong radio waves in the anechoic chamber. Developed for use in anechoic chambers, the system itself excels in EMI and EMS. It can also be used for BCI testing. *Recommended testing equipment by American automotive manufacturers! 【Catalog Contents】 ■What is the EMC test optical fiber system ■FO-HBST, FO-HBSR (Signal frequency DC to 1 MHz) ■FO-HBSTVR, FO-HBSRVR (DC to 8 MHz) ■FO-ST, FO-SR (DC to 20 kHz) ■FO-CAN (Maximum signal transfer speed 1 Mbit/s) *You can download the catalog from the "Download" section below! Please feel free to contact us for more detailed information.
