306-028-421-104

Overview

The EDAC Inc. 306-028-421-104 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a dual female configuration with 56 positions arranged in a single row. The connector utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contact plating is specified as tin, and the insulator body is constructed from thermoplastic polyester. The unit operates within a temperature range of -40°C to +105°C.

Feature Summary

Accepts PCBs with a nominal thickness of 0.062 inches (1.57mm)
Features a low profile insulator body design
Utilizes a single centerline row configuration

Applications

Panel-mounted electronic assemblies requiring card edge interfacing
Industrial control systems utilizing 3.96mm pitch board standards
Equipment operating in environments up to 105°C

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm current manufacturing status and RoHS compliance. Ensure that the required PCB thickness aligns with the 1.57mm specification. Confirm that the tin-plated contacts meet the environmental requirements for the intended application. Cross-reference the 56-position count with system design constraints before procurement.

Selection Notes

Select this component when a dual female card edge connector with a 3.96mm pitch is required for panel mounting. The 56-position capacity suits high-density interconnect needs within the 306 series form factor. Consider the tin plating option if gold plating is not strictly necessary for the specific signal integrity or wear requirements of the application.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles. The 306-028-421-104 specifically represents a variant optimized for 56-position interfaces with a 3.96mm spacing, fitting into the broader ecosystem of EDAC's industrial-grade interconnect solutions.
