Overview
The EDAC Inc. 306-026-421-107 is a standard card edge connector from the 306 series, designed for vertical panel mount applications. It features a dual female configuration with 52 total positions arranged in two rows of 26 contacts each. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates PCBs with a thickness of 1.57 mm. Contacts are tin-plated copper alloy, rated for 5 A current, while the green thermoplastic insulator provides structural support.
Feature Summary
- Dual female contact configuration for secure interface with circuit cards
- Vertical mounting orientation suitable for panel installation
- Tin-plated copper alloy contacts ensure reliable electrical connection
Applications
- Interface connections for printed circuit boards
- Panel-mounted electronic assemblies requiring high-density connections
- Industrial control systems utilizing standard card edge interfaces
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and row configuration, as variations exist within the 306 series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required PCB thickness and mounting style for the target application design.
Selection Notes
Select this component when a dual-row, 52-position card edge connector with a 3.96 mm pitch is required. The vertical panel mount style is appropriate for chassis installations where space efficiency is prioritized. Verify that the tin-plated contacts meet the environmental and conductivity requirements of the specific circuit design.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors, which offers various position counts and configurations. The series is characterized by its robust thermoplastic housing and standardized pitch dimensions, facilitating compatibility with a wide range of PCB designs in industrial and commercial electronics applications.
Replacement Considerations
Cross-reference with other EDAC 306 series variants such as 306-026-421-158 for potential pinout or plating differences. Ensure any substitute maintains the same 52-position count, 3.96 mm pitch, and vertical panel mount form factor to guarantee mechanical and electrical compatibility.
