Line-up of the MX77 Series Compact, Low-profile Automotive ECU Connectors Has Been Expanded
Octoer 6, 2020
JAE announces the launch of a new cable-side socket connector to add to the MX77 Series of compact, low-profile board-to-cable connectors for automotive ECU applications. The new MX77D achieves a 30% lower profile than the conventional MX77 Series products, offering further connector miniaturization for the automotive and relative markets.
Together with the existing MX77A connector series, the MX77D will be available within the MX77 Series.
Installation of ADAS (Advanced Driver Assistance System) sensors and ECU (Electronic Control Units) communications equipment for connected cars continues on the rise. Due to limited integration space manufacturers now face, a need for smaller and thinner ECU modules developed. This trend continues as justification to prioritize miniaturization for ECU connectors. In response to these needs, JAE launched the MX77A of compact, low-profile connectors for automotive ECU’s. JAE is currently providing these to the Japanese, European and American automotive manufacturers and Tier 1 suppliers.
More recently, an increased demand for larger battery capacity in EV’s (Electric Vehicles) and PHEV’s (Plug-in Hybrid Electric Vehicles) has led to a particularly strong need for smaller and lower profile connectors that ultimately secure space for components used in battery modules.
To cater to these needs, we have added the new MX77D cable-side socket connector. It offers a 30% lower profile than the current MX77A, included in the MX77 Series lineup of in-vehicle board-to-cable connectors.
The MX77D connector has a height of 9.5mm. By simplifying the connector locking structure, a 30% height reduction is achieved when compared to the MX77A.
In addition, ISO thin wall wire of 0.35sq is now applicable to all cavities when using the MX77D.
Despite the MX77D socket height reduction, the conventional MX77A is compatible as its socket terminal and board side mating connector.
The MX77D is available from 4 positions to 40 positions and contained within the MX77 Series.
