Overview
The EDAC Inc. 306-032-420-158 is a dual-edge female card edge connector designed for standard printed circuit board applications. It features 64 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes tin-plated contacts and accepts PCBs with a thickness range of 0.054 to 0.070 inches. Constructed with a green thermoplastic insulator, it supports a flange feature for flush mounting using 4-40 threaded inserts. The component operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual-edge configuration with 64 positions for high-density interconnect
- Flush mount design with integrated flange and 4-40 threaded insert openings
- Tin-plated contacts on a 0.156-inch pitch for reliable signal transmission
- Compatible with standard PCB thicknesses between 0.054 and 0.070 inches
Applications
- Standard card edge interface connections
- Flush-mount electronic enclosures requiring secure board retention
- Industrial control systems operating within specified thermal ranges
Procurement Notes
Verify the specific contact plating finish against project requirements, as sources indicate variations between tin and gold finishes for similar part numbers. Confirm that the required PCB thickness falls strictly within the 0.054 to 0.070 inch acceptance window. Ensure the mounting hardware matches the 4-40 threaded insert specification for proper mechanical installation.
Selection Notes
Select this component when a dual-edge connector with a wide 0.156-inch pitch is required for flush mounting applications. Consider the tin-plated contact option if cost efficiency is prioritized over maximum corrosion resistance. Verify that the target PCB stack-up aligns with the specified thickness tolerance to ensure proper contact engagement and mechanical stability during operation.
Part Context
This connector belongs to the EDAC 306 series of edgeboard connectors, which are characterized by their robust construction and suitability for standard card edge interfaces. The series offers various position counts and pitch options to accommodate different density requirements. The 306-032-420-158 specifically addresses needs for higher pin counts with a wider spacing profile compared to finer-pitch alternatives.
Replacement Considerations
Direct substitutes may include other EDAC 306 series parts with matching 64-position dual-edge configurations and 0.156-inch pitch. Verify compatibility regarding flange style, mounting hole patterns, and PCB thickness acceptance before interchange.
