Key Features
- 40-position dual-row card edge connector with beryllium copper contacts for superior spring force retention over 500+ mating cycles
- Gold-over-nickel (AU ON NI) mating finish delivers low and stable contact resistance for reliable high-speed signals
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly in high-volume PCB production
- Compact 0.887-inch body with 0.275-inch breadth fits space-constrained card edge interface designs
Applications
The MEC1-120-02-F-D-A-K-TR is designed for board-to-card-edge interface applications in communications modules, embedded computing systems, and instrumentation where a compact 40-position dual-row card edge connection is required. Its beryllium copper contacts with gold-over-nickel finish maintain reliable low-resistance contact across hundreds of card insertions and removals. The tape-and-reel format is optimized for high-volume SMT production lines assembling consumer electronics, networking hardware, and industrial control boards.

Frequently Asked Questions
Why does the MEC1-120-02-F-D-A-K-TR use beryllium copper contacts instead of phosphor bronze?
Beryllium copper provides higher yield strength and superior spring-back compared to phosphor bronze, maintaining consistent contact force throughout the connector's service life. For the MEC1-120 card edge connector, this means the gold-over-nickel mating contacts retain their clamping force on the card edge after 500 or more insertions, keeping contact resistance stable below 20 mΩ even in applications subject to thermal cycling between -40 °C and +85 °C.
How does the TR (tape-and-reel) packaging of MEC1-120-02-F-D-A-K-TR benefit high-volume PCB assembly?
The TR suffix indicates that MEC1-120-02-F-D-A-K-TR connectors are supplied on tape-and-reel, typically in quantities of 1,000 or 2,000 pieces per reel, compatible with standard SMT pick-and-place feeders. This eliminates manual tube loading, reduces placement errors, and supports continuous automated assembly at throughput rates exceeding 3,000 components per hour on modern placement systems, significantly lowering per-unit assembly cost.
What is the body length and breadth of the MEC1-120-02-F-D-A-K-TR, and how compact is its PCB footprint?
The MEC1-120-02-F-D-A-K-TR has a body length of 0.887 inch, body breadth of 0.275 inch, and body depth of 0.35 inch. This compact form factor accommodates 40 dual-row positions in under 0.9 inch of PCB length, making it well-suited for space-constrained card edge interface designs where multiple signal lines must be connected without consuming large PCB real estate.
For a removable daughter card design, when is the MEC1-120-02-F-D-A-K-TR a better choice than a standard board-to-board connector?
Card edge connectors like the MEC1-120-02-F-D-A-K-TR are preferable when the daughter card must be insertable without a mating header, reducing cost and component count on the plug-in board. The 40-position dual-row layout and beryllium copper contacts with gold-over-nickel finish support reliable connections across 500+ card insertions. This suits field-replaceable module architectures in industrial controllers, network equipment, and test instruments where cards are swapped periodically.
