Overview
The EDAC Inc. 306-027-420-108 is a standard card edge connector from the 306 Series, designed for vertical panel mount applications. It features a single row of 54 positions with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are tin-plated copper alloy, rated for 5 A current. The insulator body is green thermoplastic polyester with a height of 0.460 inches (11.68 mm). Operating temperature ranges from -40°C to +105°C.
Feature Summary
- Vertical panel mount design for secure board integration
- Single centreline row configuration with 0.156 inch spacing
- Accepts 0.062 inch nominal thickness PCBs
- Low profile insulator body construction
Applications
- Industrial control systems requiring robust card edge connections
- Telecommunications equipment interface modules
- Test and measurement instrumentation backplanes
- Automotive electronics sub-assemblies
Procurement Notes
Verify component authenticity through authorized EDAC distributors or certified partners. Confirm RoHS compliance status via official datasheets before procurement. Ensure storage conditions maintain integrity of tin-plated contacts. Validate mechanical dimensions against target PCB layout specifications. Request batch-specific documentation for quality assurance records.
Selection Notes
Select this model when vertical orientation and single-row connectivity are required. The 54-position count suits moderate-density signal routing. Tin plating offers cost-effective conductivity for non-corrosive environments. Verify PCB thickness compatibility at 1.57 mm prior to integration. Consider thermal limits up to 105°C for high-temperature operational scenarios.
Part Context
Part of the EDAC 306 Series standard card edge connectors. Designed for reliable electrical interconnection in modular electronic systems. Compatible with dual-edge card insertion methods. Manufactured by EDAC Inc., specializing in connector solutions for industrial and commercial applications.
Replacement Considerations
Cross-reference with other 306 Series variants for position count differences. Verify identical 3.96 mm pitch and 1.57 mm board thickness compatibility. Check pinout configurations if substituting within the same series family.
