Overview
The EDAC Inc. model 306-027-520-102 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a dual female configuration with 27 positions per bay across two rows, totaling 54 contacts. The connector utilizes a 0.156-inch (3.96 mm) pitch and accommodates a board thickness of 1.57 mm. Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The housing is made of green thermoplastic material, providing structural integrity and insulation.
Feature Summary
- Dual-edge female contact configuration for secure card insertion
- Gold-plated copper alloy contacts for corrosion resistance
- Thermoplastic housing with vertical mounting orientation
Applications
- Industrial control system interface connections
- Telecommunications equipment backplanes
- Consumer electronic module interconnects
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific ordering suffix matches the required pin count and termination style. Ensure compliance with RoHS directives if applicable to your assembly requirements. Check regional availability as distribution status may vary by location.
Selection Notes
Select this connector when a dual-row card edge interface with a 3.96 mm pitch is required. The 54-position capacity suits applications needing moderate I/O density. Verify that the host PCB thickness aligns with the 1.57 mm specification. Consider the panel mount style for fixed installations rather than board-to-board stacking.
Part Context
This component belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and row configurations to support diverse electronic assembly needs. EDAC has manufactured these connectors since its founding in 1966, establishing a reputation for reliable interconnect solutions in industrial and commercial sectors.
Replacement Considerations
Compatible substitutes within the same series include models with identical pitch and position counts, such as the 306-027-520-158. Ensure any replacement maintains the dual female contact type and gold finish specifications to preserve electrical performance and mechanical fit.
