305-036-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-036-521-558 is a standard card edge connector from the 305 series, designed for dual-edge board interfaces. It features 36 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms.

• Gold-plated contacts on copper alloy substrate for enhanced conductivity
• Supports between-contact and in-contact polarizing keys for secure alignment
• Low-profile insulator body facilitates compact panel or chassis mounting

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical variations such as flange type, thread insert specifications, and mating key compatibility. Ensure that the selected variant matches the required polarizing key configuration and mounting style for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with 3.96 mm pitch is required for 1.57 mm thick boards. Consider the 5 A current rating and 1800 VACrms dielectric strength for high-reliability applications. Evaluate the need for polarizing keys and specific flange features before finalizing the part number selection.

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 options, all sharing common electrical characteristics and dimensional standards for .156 inch pitch interfaces. The 305 series is widely used in modular electronic systems requiring robust mechanical retention and stable electrical performance.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-036-521-521 and 305-036-521-507, which share identical electrical parameters and mechanical dimensions but may differ in housing color or specific flange configurations.
