Key Features
- 120-position dual-row card edge receptacle on 0.050 inch (1.27 mm) pitch, providing 60 contacts per row for high-density edge card interconnects
- Right-angle (RA1) orientation allows the mating card edge to insert parallel to the mother board surface, reducing assembly height
- PEG board mounting posts provide mechanical stability and accurate positioning during pick-and-place and reflow soldering
- RoHS-compliant construction with PEG retention ensures compatibility with lead-free solder processes and modern environmental regulations
Applications
The MEC6-120-02-S-D-RA1 is used in industrial computing, telecommunications backplane assemblies, and embedded systems where daughter cards or peripheral modules connect to a mother board via a 120-position card edge interface on 0.050 inch pitch. The right-angle orientation suits enclosure-constrained designs where card insertion must be perpendicular to the motherboard rather than perpendicular to the PCB plane, such as front-panel module slots and rack-mounted communication cards. The dual-row 120-position format supports simultaneous data bus, power, and control signal routing through a single edge connector.

Frequently Asked Questions
How many positions and rows does the MEC6-120-02-S-D-RA1 provide, and what is the contact pitch?
The MEC6-120-02-S-D-RA1 provides 120 positions in a dual-row layout with 60 contacts per row on a 0.050 inch (1.27 mm) pitch. This high-density configuration supports large data buses, power distribution, and control signals across a single card-edge receptacle in industrial and telecom backplane designs.
What does the right-angle (RA1) orientation of the MEC6-120-02-S-D-RA1 mean for PCB assembly?
The right-angle orientation means the card edge receptacle is mounted so the mating daughter card inserts horizontally, parallel to the motherboard surface, rather than perpendicular to it. This reduces overall assembly height and suits enclosures or rack slots where vertical card insertion is not feasible, such as front-panel module bays where total stack height must be kept below 30 mm.
How does the PEG mounting option on the MEC6-120-02-S-D-RA1 assist during PCB assembly?
The PEG mounting posts snap into holes on the PCB to hold the 120-position receptacle in place before and during reflow soldering. This prevents the connector from shifting when the board passes through the reflow oven, ensuring all 120 contact pads align accurately with their PCB footprint and reducing the risk of bridging or open joints on the fine 0.050 inch pitch.
In what systems is the MEC6-120-02-S-D-RA1 most commonly used?
This card edge receptacle is commonly used in industrial single-board computers, telecommunications line cards, FPGA development platforms, and embedded control backplanes where a daughter card or mezzanine module must deliver 120 signal and power connections through a single 0.050 inch pitch edge connector. The right-angle receptacle style is particularly prevalent in 1U and 2U rack-mount assemblies where horizontal card insertion into the front face of a chassis is the preferred mechanical architecture.
