305-076-521-568

Edgeboard Connectors Overview

The EDAC 305-076-521-568 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 76 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses of 1.37 mm to 1.78 mm. The contacts are gold-plated copper alloy with a 10.0 µin (0.25 µm) finish, rated for 5 A continuous current and 1800 VACrms insulation. The housing is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual-row configuration with half-beam contact type for reliable signal transmission
• Thermoplastic polyester housing provides thermal stability and electrical insulation

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge interfaces
• Telecommunications equipment utilizing dual-edge board connections
• Test and measurement devices needing high-reliability panel-mounted headers

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required polarizing key compatibility, as the 305 series accepts both between-contact and in-contact types. Confirm the insulation resistance rating of 5 GOhms meets system requirements. Ensure the operating temperature range of -40°C to +105°C aligns with environmental conditions. Check RoHS compliance status before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with polarizing key support is necessary. The 3.96 mm pitch and 76-position count define the interface density. Consider the 5 A current rating and 1800 VACrms voltage capability for power and signal integrity. Verify the panel mount style and solder pin termination match the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-076 variant specifically provides 76 positions in a dual-row arrangement. It is part of a broader family including similar models like 305-080-555-568, sharing common pitch and material specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-520-204 or 305-080-555-568, depending on position count requirements. Verify identical pitch, row configuration, and polarizing key compatibility before substitution.
