Key Features
- 80-position dual-row card edge receptacle on 0.635 mm ultra-fine pitch for high-density interconnects
- Gold-plated mating contacts with nickel barrier tin termination ensure low-resistance reliable signal integrity
- Right-angle through-hole mounting with PEG board retention provides robust mechanical stability on PCBs
Applications
The MEC6-140-02-S-D-RA1 is ideal for high-density board-to-board or module-to-PCB connections in data storage, networking switches, and industrial computing systems. Its right-angle orientation and 0.635 mm pitch make it particularly useful in edge-mounted expansion card applications where space and signal channel count are both critical design constraints.

Frequently Asked Questions
What pitch and position count does the MEC6-140-02-S-D-RA1 support for card-edge connections?
The MEC6-140-02-S-D-RA1 provides 80 positions on a 0.635 mm pitch in a dual-row card edge receptacle format. This combination enables very high contact density within a body length of approximately 1.125 inches, making it suitable for data-intensive interfaces requiring many parallel signal lanes.
What contact finish does the MEC6-140-02-S-D-RA1 use, and why does it matter for long-term reliability?
The mating contacts are gold-plated to ensure low contact resistance and excellent corrosion resistance across thousands of mating cycles. The termination contacts use tin over a nickel barrier, which prevents tin whisker migration and maintains solderability to the PCB pads during reflow or wave soldering processes.
In which system-level applications is the MEC6-140-02-S-D-RA1 right-angle card-edge connector most commonly used?
This connector is commonly deployed in network switching cards, FPGA expansion modules, and industrial backplane systems where a right-angle edge card interface connects a daughter card perpendicular to a main PCB. Its 80 positions at 0.635 mm pitch supports parallel data buses of 32 bits or more alongside power and ground contacts in a compact footprint.
