305-050-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-207 is a standard card edge connector from the 305 series, designed for panel-mounted vertical installation. It features 50 positions arranged in a dual-row configuration with a 0.156-inch (3.96 mm) contact spacing and 0.140-inch (3.56 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are gold-plated copper alloy with a maximum resistance of 10 milliohms, rated for 5 amps current. The insulator body is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female connector design accepting non-specified dual-edge cards
• Gold plating on mating area with tin plating on tails and nickel underplating
• Low profile insulator body construction
• Panel mount vertical orientation with solder lug termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm termination type and plating specifications, as variations exist within the 305 series. Confirm that the target application requires the standard 0.062-inch board thickness compatibility. Ensure environmental conditions remain within the specified -40°C to +105°C operational range. Check RoHS compliance status if required by project regulations. Validate mechanical fit against panel cutout dimensions before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 50-position interface is required for vertical panel mounting. The 0.156-inch pitch suits applications needing wider spacing than standard 0.100-inch connectors. Gold plating ensures reliable signal integrity for general-purpose connections. Consider the low-profile body for space-constrained enclosures. Verify that the solder lug termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors with 0.156-inch spacing. The series includes various position counts and termination options. The 305-050 variant specifically addresses high-density connection needs in a dual-row format. It complements other EDAC interconnect solutions for modular system designs.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-050-500-202 and 305-050-555-208, provided they match the required termination style and plating specifications. Verify dimensional compatibility with existing panel cutouts and PCB stack heights before substitution.
