Overview
The EDAC Inc. 306-032-520-158 is a dual-edge female card edge connector from the 306 series, designed for panel mounting applications. It features 32 positions with a 0.156-inch (3.96mm) contact spacing and utilizes gold-plated cantilever contacts. The housing is constructed from thermoplastic polyester and is green in color. This component accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). It operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.
Feature Summary
- Dual-edge female configuration with cantilever contact design for reliable board insertion
- Gold-plated contacts ensure durable electrical performance in demanding environments
- Thermoplastic polyester insulator provides stability across a wide operating temperature range
- Panel mount installation with flange features for secure mechanical attachment
Applications
- Industrial control systems requiring robust card edge interfaces
- Communication equipment utilizing high-reliability interconnects
- Medical devices needing stable connections within specified thermal limits
Procurement Notes
Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, termination style, and plating thickness. Ensure the selected variant matches the required PCB thickness tolerance and mounting orientation. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability and lead times before finalizing procurement orders.
Selection Notes
Select this connector when a dual-edge interface with 0.156-inch spacing is required for panel-mounted applications. Consider the thermoplastic insulation material and gold plating for corrosion resistance. Verify that the target PCB thickness falls within the 0.054 to 0.070-inch range to ensure proper contact engagement and mechanical fit during assembly.
Part Context
This component belongs to the EDAC 306 series, which specializes in card edge connectors with 0.156-inch spacing. The series offers various configurations including single and dual edges, different mounting styles, and multiple termination options. The 306 series is widely used in industrial and commercial electronics where reliable, high-density interconnections are necessary.
Replacement Considerations
Direct substitutes include other EDAC 306 series variants with matching 32-position dual-edge specifications. Check for identical 0.156-inch spacing and compatible PCB thickness ranges. Alternative manufacturers may offer similar connectors, but mechanical dimensions and contact geometry must be verified for interchangeability.
