Key Features
- 20-position dual-row 0.635 mm pitch mini edge card receptacle with right-angle body orientation for low-profile edge mount designs
- Peg (PEG) board mounting option providing mechanical retention to PCB during soldering and in-service vibration stress
- Tin over nickel barrier termination finish enabling reliable solder joint formation and resistance to tin whisker growth in lead-free assemblies
Applications
MEC6-110-02-S-D-RA1 is used in compact electronic assemblies requiring a right-angle mini edge card interface with 0.635 mm pitch, such as SSD modules, camera sensor boards, and embedded computing daughter cards. The right-angle orientation allows plug-in cards to mount parallel to the host PCB, reducing overall stack height, which is ideal for slim form-factor industrial computers, medical imaging modules, and portable test instruments.

Frequently Asked Questions
What is the contact pitch and total position count of MEC6-110-02-S-D-RA1?
MEC6-110-02-S-D-RA1 features a 0.635 mm contact pitch in a dual-row configuration providing 20 total contact positions. The compact 0.635 mm pitch allows the connector body to fit in a footprint of approximately 0.375 inch body length, making it one of the smallest card edge receptacles available for high-density interconnect applications.
Why is a right-angle orientation chosen for MEC6-110-02-S-D-RA1 in slim enclosure designs?
The right-angle (RA) body orientation positions the mating edge perpendicular to the PCB surface, allowing a daughter card or module to slide in horizontally parallel to the main board. This reduces the total assembly height by the thickness of the mating card, typically saving 2 mm to 5 mm of vertical clearance compared to a vertical edge card receptacle in the same application.
How does the peg mounting feature on MEC6-110-02-S-D-RA1 improve assembly reliability?
The PEG board mounting pegs press into dedicated PCB holes and mechanically lock the connector body to the board before and during soldering. This prevents the connector from shifting or tilting during reflow at temperatures up to 260°C, ensuring that the 20 tin-over-nickel termination contacts remain aligned with their pads for a consistent solder joint and long-term mechanical robustness under vibration.
