306-020-520-101

Overview

The EDAC Inc. 306-020-520-101 is a standard card edge connector from the 306 series, designed for panel mount installation with a vertical orientation. It features 40 positions in a dual female configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The insulator body is made of green thermoplastic material, providing structural integrity and electrical insulation.

Feature Summary

• Dual edge female contact configuration for secure board retention
• Gold-plated copper alloy contacts for corrosion resistance
• Vertical panel mount design with low profile insulator body
• Compatible with 1.57 mm nominal thickness PCBs

Applications

• Industrial control system interconnects
• Medical device internal wiring
• Aerospace instrumentation modules
• Computing and storage hardware interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and housing color specifications. Ensure the target application supports the required 1.57 mm board thickness and vertical panel mounting constraints. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with the latest EDAC catalog to avoid substitution errors.

Selection Notes

Select this component when a dual-edge female connector with 40 positions is required for vertical panel integration. The 3.96 mm pitch accommodates standard board layouts while the gold finish ensures durability in high-cycle applications. Consider the thermoplastic housing material for general-purpose insulation needs. Evaluate the mechanical stability provided by the panel mount style against space-constrained alternatives.

Part Context

This component belongs to the EDAC 306 series, which specializes in card edge and rack & panel connectors. Established since 1966, EDAC provides interconnect solutions for computing, medical, aerospace, and industrial sectors. The 306 series is characterized by its robust construction and compatibility with various board thicknesses, serving as a critical link in complex electronic assemblies requiring reliable signal routing.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for verified substitute part numbers. Variations in position count, contact plating, or board thickness require distinct part numbers within the same series. Do not assume interchangeability with other series without verifying dimensional and electrical parameters.
