305-022-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-258 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features a dual female configuration with 22 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are constructed from copper alloy with gold plating, rated for 5 A current at +105°C maximum operating temperature. The housing is made of thermoplastic material, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural integrity and electrical isolation
• Panel mount design with solder pin termination for stable integration

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Test and measurement instrument module mounting

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact mechanical dimensions and contact finish specifications. Ensure compatibility with target PCB card thickness within the specified range. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 22-position count suits moderate-density signal routing needs. Verify that the target circuit board thickness falls between 1.37 mm and 1.78 mm to ensure proper contact engagement. Consider the vertical orientation and through-hole soldering method for assembly constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles to accommodate different design requirements. The 305-022 variant specifically addresses applications needing a mid-range contact density with robust panel mounting capabilities.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with differing position counts or flange configurations. Direct substitutes must maintain the 3.96 mm pitch and dual female contact type to ensure mechanical and electrical compatibility.
