Overview
The EDAC Inc. 306-022-420-108 is a standard card edge connector designed for panel mount applications. It features a dual row configuration with 44 positions and a pitch of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It supports a PCB thickness of 1.57 mm and offers a current rating of 5 A per contact. The unit operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.
Feature Summary
- Dual row female connector design for secure board-to-board or backplane interconnection
- Gold-plated contacts ensure reliable signal transmission and corrosion resistance
- Thermoplastic polyester housing provides structural stability and electrical insulation
- Panel mount vertical orientation facilitates standardized chassis integration
Applications
- Industrial control systems requiring robust card edge interfaces
- Telecommunications equipment backplanes
- Test and measurement instrumentation modules
- Computer peripheral expansion cards
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, insulator color, and mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual row configuration matches the circuit board layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a high-density 44-position interface is required in a dual row format. The 3.96 mm pitch accommodates standard edge card widths. Consider the 5 A current rating and wide operating temperature range for demanding environments. Verify that the panel mount requirement aligns with the system enclosure design constraints.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic insulators and copper alloy contacts. The 306 series offers various position counts and row configurations to support diverse electronic module designs across multiple industries.
Replacement Considerations
Consult the official EDAC cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the same 44-position count, dual row structure, and 3.96 mm pitch. Verify mechanical dimensions and electrical ratings match the original specifications.
