MX81 Series

MX81 Series

JAE has released the MX81 Series of non-waterproof compact connectors for connecting in-vehicle electronic devices such as ECUs and sensors. This series employs the same socket terminals as the currently available MX80 Series of waterproof connectors, allowing the same terminals and crimp tools to be used for a broad range of waterproof and non-waterproof areas of the vehicle.

Due to the increase in user experience features, the spread of ADAS, and electrification, the number of ECUs and electronic devices mounted in the interiors of vehicles is increasing. This is driving the need for a larger amount of compact devices and connectors to fit in the limited space. At the same time, the use in automotive applications require these connectors to have high contact reliability and robustness to ensure safe and long term use.
