Automotive Ethernet IEEE 100BASE-T1 Compatible MX74 Series Board-to-Cable Connector Has Been Launched

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


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

  • Compatible with IEEE 100BASE-T1 Automotive Ethernet differential transmission. Meets the transmission characteristics of IEEE 100BASE-T1 Definitions for Communication Channel Version 1.0 published by OPEN Alliance Inc.
  • UTP cable is applicable
  • Provided as an individual connector for the socket side (please contact us for harnesses)
  • 2 position products have 2 key codes with different colors

*Open Alliance is a standards organization formed to coordinate Automotive Ethernet technology specifications.
