Overview
The EDAC Inc. 306-020-520-102 is a standard card edge connector from the 306 series, designed for vertical panel mounting. It features a dual female configuration with 40 positions and a 0.156-inch (3.96 mm) pitch. The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic housing provides insulation resistance of 5 Gohms. It supports a board thickness of 1.57 mm and operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual female contact configuration ensures reliable mating with card edge boards.
- Vertical panel mount style facilitates secure installation in chassis applications.
- Gold-plated copper alloy contacts offer corrosion resistance and stable conductivity.
Applications
- Medical interconnect solutions such as ventilators and CPAP machines
- Ambulance medical equipment connections
- General industrial panel-mounted circuit interfaces
Procurement Notes
Verify RoHS3 compliance status before integration into regulated assemblies. Confirm that the 40-position dual female variant matches the target PCB edge design. Ensure the 0.156-inch pitch aligns with the host board specifications. Check regional availability as distribution may vary by location.
Selection Notes
Select this component when a vertical, panel-mount interface is required for high-reliability connections. The 40-position count suits moderate-density signal routing. Verify that the 1.57 mm board thickness tolerance accommodates the target PCB stack-up. Consider the operating temperature range for environmental suitability.
