306-028-420-112

Overview

The EDAC Inc. 306-028-420-112 is a dual-edge card edge connector designed for through-hole mounting. It features 56 positions with a 0.156-inch (3.96mm) contact spacing and two rows of contacts. The connector utilizes tin-plated copper alloy cantilever contacts and a green thermoplastic insulator. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The component operates within a temperature range of -55°C to 85°C and complies with RoHS3 standards.

Feature Summary

Dual-edge configuration with cantilever spring contacts for reliable board insertion
Through-hole termination method ensures secure PCB attachment
Tin-plated contact finish provides corrosion resistance
Green thermoplastic insulation material supports standard operating environments

Applications

Industrial control system backplanes
Telecommunications equipment interconnects
Consumer electronics module connections

Procurement Notes

Verify the specific ordering suffix to confirm contact plating, color, and pin count match project requirements. Confirm that the PCB design accommodates the 0.156-inch spacing and specified card thickness range. Ensure compliance with RoHS3 regulations if required by the target market. Check lead times as distribution availability may vary.

Selection Notes

Select this connector when a dual-edge interface with 0.156-inch spacing is required. The 56-position count suits moderate-density applications. Tin plating offers cost-effective durability compared to gold. Verify that the housing height and flange dimensions fit the mechanical enclosure constraints.

Part Context

This component belongs to the EDAC 306 series of edgeboard connectors. The series provides various position counts and spacing options for general-purpose interconnect needs. The 306-028-420-112 variant specifically addresses dual-edge applications requiring robust mechanical retention and standard electrical performance.
