IRISO 's wire-to-board (WtoB) connectors use 0.5mm terminals instead of the conventional harness terminals 0.64mm terminals, reducing the board volume by approximately 55% compared to our conventional products, achieving compactness and weight reduction for the mobility market where electrification is progressing. In addition, they are highly heat-resistant and robust, making them safe to use in the internal connections of powertrain devices in construction and agricultural machinery, which are used in harsh environments, and in factory automation devices.
