Automotive Ethernet IEEE 100BASE-T1 Compatible MX74 Series Board-to-Cable Connector Has Been Launched
June 2, 2022JAE has developed and launched the MX74 Series, an Automotive Ethernet standard IEEE 100BASE-T1 compatible connector featuring excellent quality and high-speed performance.

Along with the progress of advanced driver assistance systems (ADAS) in recent years, there has been an increase in high performance in-vehicle components such as cameras and sensors. As a result, in-vehicle networks must transmit large amounts of data at high speeds, and Ethernet is increasingly being adopted for the communication between electronic control units (ECUs) or with other end-point devices.
Connector harnesses are also required to handle the high speed and low latency data transmission with higher signal quality.
JAE has developed the MX74 Series board-to-cable connector as an IEEE 100BASE-T1 compatible product, standardized at IEEE 802.3bw, featuring high quality transmission. This product is used with unshielded twisted pair (UTP) cables, contributing to the lighter weight of vehicle bodies.
*IEEE is an organization in the field of electrical and information engineering and a technology standardization institution based in the United States.
Features
