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.

In light of this situation, JAE has developed the MX81 Series of connectors, which use standard automotive terminal designs (terminal tab size of 0.64 mm and contact pitch of 2.54 mm), but are more compact, at approximately 60% of the size of existing JAE products.

From ECUs to sensors, lighting, and various automotive applications, the MX81 Series delivers unparalleled performance and compatibility, meeting the demands of the modern automotive industry.
