Overview
The EDAC Inc. 306-022-520-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight orientation. It features 44 positions arranged in a dual female configuration with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. Rated for 5 A current, it accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm).
Feature Summary
- Dual-edge female contact configuration for secure board insertion.
- Gold-plated copper alloy contacts ensure reliable signal transmission.
- Thermoplastic polyester insulator provides structural stability.
- Through-hole solder termination supports robust PCB integration.
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Consumer electronics module interfaces
- Medical device circuit board connections
Procurement Notes
Verify the specific ordering suffix to confirm contact plating thickness and material composition, as variations may exist within the 306 series. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the straight through-hole mounting style aligns with the mechanical assembly requirements. Cross-reference the manufacturer datasheet for precise dimensional tolerances and environmental operating limits to guarantee long-term reliability in the intended application environment.
Selection Notes
Select this component when a dual-edge female connector with 3.96 mm spacing is required for high-current applications up to 5 A. The choice is driven by the need for gold-plated contacts to minimize contact resistance and corrosion. Consider the 1.57 mm board thickness constraint and the through-hole mounting method. This model is suitable for environments requiring durable thermoplastic polyester insulation and standardized industrial form factors.
