Key Features
- 20-position dual-row card-edge design at 0.635 mm pitch for high-density, low-profile board-to-board connections
- 10 µin gold over 50 µin nickel contact plating provides low contact resistance and extended mating cycle durability
- Locating posts ensure precise PCB registration during assembly, preventing misalignment in automated board-to-board stacking
- Vertical orientation with compact 0.438 in x 0.341 in footprint minimizes PCB real estate in dense module designs
Applications
The MEC6-110-02-L-DV-A is designed for mezzanine and daughter-card interconnection in compact embedded computing, medical instrumentation, and industrial control modules where a reliable 0.635 mm pitch edge-card interface is required. Its 20 positions accommodate data buses, power rails, and control signals in a single connector, reducing wiring complexity in multi-board systems. The locating posts and gold-plated contacts ensure consistent mating alignment and long service life in applications subject to frequent board insertion and removal.

Frequently Asked Questions
What pitch and position count does MEC6-110-02-L-DV-A provide for edge-card interconnection?
The MEC6-110-02-L-DV-A provides 20 positions at a 0.635 mm pitch in a dual-row card-edge configuration. This fine pitch allows 10 contacts per row, supporting high-density signal and power routing in a body that measures approximately 11.1 mm long. The 0.635 mm pitch is compatible with Samtec's MEC6 card-edge series and requires a matching edge-card PCB finger pattern on the daughter board.
How does the gold-over-nickel contact finish in MEC6-110-02-L-DV-A affect mating reliability?
The MEC6-110-02-L-DV-A uses 10 µin gold over 50 µin nickel plating on the mating contact surfaces. This plating stack provides contact resistance typically below 30 milliohms per contact, resists tarnish and oxidation in humid or mildly corrosive environments, and maintains stable electrical performance over hundreds of mating cycles. Gold plating is especially important for low-level signal contacts where even slight oxidation can introduce noise or open-circuit failures.
What is the purpose of the locating posts on MEC6-110-02-L-DV-A and how do they affect PCB design?
The locating posts on MEC6-110-02-L-DV-A register the connector precisely to the PCB footprint during assembly, preventing lateral or rotational misalignment of the 20 contacts before soldering. They engage with matching through-holes in the PCB, eliminating the need for pick-and-place tooling to hold the part in position during reflow. Designers must include the locating post holes in the PCB layout using the dimensions specified in the Samtec MEC6 series datasheet (body depth 0.341 in, body length 0.438 in).
In which industries and PCB stack-up scenarios is MEC6-110-02-L-DV-A most commonly deployed?
The MEC6-110-02-L-DV-A is used primarily in medical devices, industrial control modules, and embedded computing daughter cards where board-to-board stack heights are constrained and fine-pitch 0.635 mm card-edge connections are required. Its 20-position dual-row layout is suitable for parallel buses carrying 8-bit or 16-bit data plus power and ground, making it common in sensor interface cards, small SBCs, and communication modules that plug into a main backplane.
