Key Features
- 20-position mini edge card connector on 0.635mm pitch delivering high contact density in a 0.438" body length
- Gold (30µin) over nickel (50µin) contact finish ensures low insertion resistance and reliable signal integrity over thousands of mating cycles
- Locating posts enable precise PCB alignment during SMT assembly, reducing misregistration in high-density 0.635mm pitch footprints
Applications
The MEC6-110-02-S-DV-A is used in compact mezzanine card interfaces for embedded computing modules, small form-factor SBCs, and wireless communication daughter cards where a 20-contact, 0.635mm pitch edge connector is required in a vertical orientation. Its gold-plated contacts and locating posts also suit high-reliability industrial and defense applications where repeated mating and precise mechanical alignment are critical at sub-millimeter pitches.

Frequently Asked Questions
What pitch and contact count does MEC6-110-02-S-DV-A provide for board-to-board mezzanine interfaces?
The MEC6-110-02-S-DV-A provides 20 contacts on a 0.635mm (0.025") pitch, arranged as a vertical receptacle for mini edge card mating. With a body length of 0.438 inches and 20 contact positions, this connector is suited for compact mezzanine interfaces on embedded computing modules, IoT gateway daughter cards, and wireless radio boards that require dense signal routing in a small connector footprint.
How does the gold-over-nickel contact finish on MEC6-110-02-S-DV-A contribute to long-term signal reliability?
The MEC6-110-02-S-DV-A uses 30µin gold over 50µin nickel contact plating, which provides excellent corrosion resistance and low contact resistance over repeated mating cycles. Gold plating at 30µin thickness is typically rated for over 200 mating cycles before measurable wear occurs, making this connector suitable for removable mezzanine cards or daughter boards that are inserted and removed during system integration, testing, or field maintenance.
What role do the locating posts on MEC6-110-02-S-DV-A play during PCB assembly at 0.635mm pitch?
At 0.635mm pitch, pad-to-pad spacing is only 0.635mm, so even a slight misalignment during SMT placement can cause solder bridging or missed contacts on one or more of the 20 positions. The locating posts on MEC6-110-02-S-DV-A insert into PCB holes to mechanically register the connector body to the board before soldering, ensuring all 20 pads align within the 0.635mm pitch tolerance and preventing placement errors during reflow.
For a compact wireless radio module design, when is MEC6-110-02-S-DV-A a better choice than a 2.54mm pitch connector?
MEC6-110-02-S-DV-A at 0.635mm pitch occupies roughly one-quarter the connector length of a 20-position 2.54mm pitch alternative for the same 20 contacts. When PCB board area is constrained to below 12mm per connector axis—common in miniaturized wireless radio, GPS, or Bluetooth module designs—the mini edge card format at 0.635mm pitch allows 20 signals to be routed through a 0.438" body, which is not achievable with larger 2.54mm or even 1.27mm pitch connectors.
