306-026-521-107

Overview

The EDAC Inc. 306-026-521-107 is a standard card edge connector designed for panel mount applications. It features a dual-edge female configuration with 52 positions arranged in two rows. The contact spacing is 3.96 mm (0.156 inches), and it accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are made of copper alloy with gold plating, providing a current rating of 5 A. The insulator body is constructed from green thermoplastic material, ensuring an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Feature Summary

• Dual-edge female connector design accommodating double-sided card edges
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic insulator housing with high insulation resistance
• Panel mount vertical installation style for secure integration

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard density card edges

Procurement Notes

Verify the specific ordering suffix to confirm pin count and contact configuration match project requirements. Ensure the PCB thickness falls within the specified acceptance range for proper mating. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders. Cross-reference the series designation to ensure compatibility with existing connector families.

Selection Notes

Select this component when a dual-edge female connection is required for single-row pitch applications. The 3.96 mm spacing accommodates standard board layouts without excessive density. Verify that the panel mount style aligns with the mechanical enclosure design. Consider the thermal rating if the application involves significant heat dissipation near the connector interface.

Part Context

This part belongs to the EDAC 306 Series, which focuses on standard density card edge connectors. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 306-026-521-107 specifically addresses applications requiring a 52-position dual-edge interface with reliable electrical performance.

Replacement Considerations

Direct substitutes may include other EDAC 306 series variants with matching position counts and spacing. Verify mechanical dimensions and contact plating specifications when considering alternative manufacturers. Ensure any replacement maintains the same current rating and temperature tolerance for system reliability.
