305-074-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-074-521-568 is a standard card edge connector from the 305 series, designed for dual female termination on non-specified double-sided cards. It features 74 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.200 inches (5.08 mm). The connector utilizes gold-plated copper alloy contacts with a half-beam terminal type and solder pin end termination. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female half-beam contacts ensure reliable engagement with double-sided card edges.
• Gold-plated copper alloy terminals provide corrosion resistance and stable electrical performance.
• Low-profile thermoplastic insulator body accommodates space-constrained panel installations.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment utilizing standardized card edge modules
• Medical devices needing high-reliability signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm plating thickness and flange characteristics. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements before finalizing the procurement order.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 74 positions is required. The 0.156-inch pitch suits general-purpose applications where standard card dimensions are utilized. Consider the vertical orientation and panel mounting style for integration into chassis designs that require direct board insertion without additional cabling.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing a modular solution for electronic interconnect needs. The 305 series is characterized by its use of thermoplastic polyester insulation and copper alloy contacts, ensuring durability in industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch, such as 305-074-521-268 or 305-074-521-504, provided the flange and termination specifications match the original design requirements.
