Overview
The EDAC Inc. 306-021-420-108 is a standard card edge connector receptacle featuring 42 positions with a 3.96 mm (0.156 inch) pitch. It utilizes gold-plated copper alloy contacts and tin-plated termination pins for solder pin end connections. Designed for panel mount installation at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The housing is constructed from thermoplastic polyester, providing an insulation resistance of 5 GOhms and a current rating of 5 A.
Feature Summary
- Dual female contact configuration designed for dual-edge card acceptance
- Vertical panel mount orientation for secure structural integration
- Gold-plated copper alloy contacts ensure reliable signal conductivity
- Thermoplastic polyester insulator body provides durable electrical isolation
Applications
- Industrial control system interface modules
- Telecommunications backplane interconnects
- Test and measurement equipment card slots
- Computing hardware expansion board connections
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and termination style matches the design requirements. Confirm that the panel cutout dimensions align with the receptacle's mechanical envelope. Ensure the target PCB thickness falls within the specified tolerance range for proper contact engagement. Check regional availability as distribution status may vary by location.
Selection Notes
Select this component when a high-density 42-position connection is required for thick PCBs. The 3.96 mm pitch offers robust spacing for higher voltage applications compared to finer pitches. Verify that the vertical mounting style fits the enclosure constraints. Consider the thermal properties of the polyester housing for operating environments.
Part Context
This part belongs to the EDAC 306 Series, which focuses on standard card edge connectors. The series provides various position counts and termination options. The 306-021-420-108 specifically addresses needs for dual-edge female connectors with high positional density in industrial form factors.
Replacement Considerations
Cross-reference with other EDAC 306 series variants for different position counts or plating options. Verify mechanical compatibility with existing panel mounts before substituting. Ensure equivalent electrical ratings are maintained if sourcing from alternative manufacturers.
