306-022-421-112

Overview

The EDAC Inc. 306-022-421-112 is a standard card edge connector from the 306 Series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 44 positions arranged in two rows of 22 contacts each. The connector utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a current rating of 5 A per contact. The housing is constructed from thermoplastic polyester, while the copper alloy contacts are tin-plated to ensure reliable conductivity.

Feature Summary

• Accepts .062" (1.57mm) nominal thickness P.C. board
• Low profile insulator body design
• .156" (3.96mm) contact spacing with single centreline row

Applications

• Panel-mounted electronic assemblies requiring vertical interconnection
• Industrial control systems utilizing standard card edge interfaces
• General-purpose PCB-to-panel connection modules

Procurement Notes

Verify the specific plating requirements against application needs, as this part uses tin plating rather than gold. Confirm that the target PCB thickness aligns with the specified 0.062-inch nominal tolerance. Ensure the panel mounting style matches the mechanical constraints of the enclosure design. Cross-reference the 44-position count with system signal requirements before finalizing procurement.

Selection Notes

Select this component when a low-profile, vertically mounted card edge solution is required for thicker PCBs. The 306 series offers robust mechanical stability for panel installations. Consider the tin-plated contacts if cost efficiency is prioritized over high-cycle durability associated with gold plating. Ensure the 0.156-inch pitch accommodates the necessary trace density for the specific circuit layout.

Part Context

This connector belongs to the EDAC 306 Series, which specializes in standard card edge connectors for panel mount applications. The series is characterized by its ability to accommodate various board thicknesses and provide reliable vertical interconnections. The 306-022 variant specifically addresses designs requiring 44 connections with a wider 0.156-inch spacing, distinguishing it from finer-pitch alternatives in the broader EDAC portfolio.

Replacement Considerations

Direct substitutes within the same series include variations in position count or plating, such as the 306-010-421-101. Verify that any replacement maintains the 0.156-inch pitch and 0.062-inch board thickness compatibility. Ensure the alternative part retains the vertical panel mount orientation and dual-row configuration to fit existing mechanical enclosures.
