Japan Aviation Electronics Industry, Ltd. (JAE) has released an additional variation to the MA01 Series floating board-to-board connectors, with an expanded floating tolerance.

Mainly, the MA01 Series floating board-board connectors are ideal for the automotive and industrial markets, where higher performance has prompted a continuous increase in information processing speeds. In response, the MA01 Series achieved both high-speed transmission that exceeds 8Gbps, equivalent to 10GBASE-KR^(*1) and PCIe Gen3^(*2). Moreover, it features high contact reliability through a unique two-point contact structure.

Wider Floating Tolerance

Thus, to meet an even wider variety of needs, JAE has added a product variation that elongates the floating tolerances in the X & Y directions from the conventional ±0.5 to ±0.8mm. With the increased floating tolerance, the MA01 Series (MA01F030VADJ) will contribute to improving customer productivity and expanding board design capabilities.

Aside from the ±0.8mm floating tolerance in X & Y directions, the new variation allows a stacking height tolerance between boards of ±0.5mm in Z-direction. Also, the two-point contact structure ensures high contact reliability. It achieved low insertion and removal forces by using rolled surface of contact. This connector operates within -40°C to +125°C. Additionally, it features excellent mating process with large guides, supporting automatic assembly and mating (mating guide length: ±1.0 mm). Moreover, it supports automatic mounting and allows for multiple connectors to be used on a single pair of boards without alignment issues. Further, it is keyed to prevent reverse mating and supports clear visibility of solder joints for easy visual inspection.

*1: 10GBASE-KR: 10 Gigabit Ethernet transmission; a communication standard for building computer networks set by IEEE, specifying communication between printed circuit boards within an application.

*2: PCIe Gen3 (PCI Express 3.0): One of the serial bus standards specified by PCI-SIG, where it calls for 8Gbps transmission speed.
