Overview
The EDAC Inc. 306-020-521-107 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features 20 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge board connections. The contacts are made of copper alloy with gold plating and utilize a cantilever contact type. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, accommodating PCB thicknesses between 1.37 mm and 1.78 mm.
Feature Summary
- Dual-edge female connection design for secure board insertion
- Cantilever contact type ensures reliable electrical engagement
- Gold-plated copper alloy contacts for corrosion resistance
- Panel mount vertical orientation with flange mounting options
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Test and measurement instrument modules
- Embedded computing hardware interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, contact plating thickness, and flange configuration. Ensure compatibility with the target PCB edge thickness and mating connector requirements before finalizing procurement orders.
Selection Notes
Select this component when a vertical, dual-edge card edge connector with a 3.96 mm pitch is required. Confirm that the application environment falls within the specified -40°C to +105°C operating temperature range and that the 5 A current rating meets the circuit demands.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and configurations, providing a modular solution for high-density interconnect applications in rugged industrial and commercial environments.
Replacement Considerations
Direct substitutes include other EDAC 306 series parts with matching 20-position, dual-edge specifications. Cross-referencing with identical pitch and contact type connectors from other manufacturers requires careful verification of mechanical dimensions and electrical ratings.
