Overview

The EDAC Inc. model 306-021-520-107 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 42 positions arranged in two rows, providing a total of 21 contacts per side. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and is constructed with copper alloy contacts that are gold plated for reliable signal transmission. The insulator body is made of thermoplastic material, offering a low-profile design suitable for space-constrained installations. It accepts printed circuit boards with a nominal thickness of 1.57 mm.

Feature Summary

Vertical panel mount installation style for secure board attachment
Dual female contact configuration with gold-plated copper alloy terminals
Low-profile thermoplastic insulator body construction

Applications

Industrial control systems requiring robust card edge interfaces
Telecommunications equipment backplanes
General-purpose electronic assemblies utilizing standard PCB thicknesses

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required flange characteristics and termination methods. Confirm that the dual female configuration aligns with the mating card edge requirements of the target assembly. Cross-reference the manufacturer datasheet for precise dimensional tolerances and environmental operating limits before finalizing procurement specifications.

Selection Notes

Select this component when a vertical panel mount solution with 3.96 mm spacing is required. Ensure the application supports a maximum operating temperature of +105°C and a minimum of -40°C. Verify that the target PCB thickness matches the specified 1.57 mm nominal dimension to guarantee proper mechanical engagement and electrical contact stability during operation.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic housings and copper alloy contacts. The 306 series provides various position counts and mounting styles, serving as a versatile interconnect solution for general electronic applications where reliable connection between a board and a chassis or backplane is necessary.
