391-034-522-204

Edgeboard Connectors Overview

The EDAC Inc. 391-034-522-204 is a standard card edge connector from the 391 series, designed for dual-edge board applications. It features a 34-position configuration with a 0.100" (2.54mm) contact spacing and two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a 10.0µin (0.25µm) finish thickness to ensure reliable signal transmission. Constructed with a black thermoplastic polyester housing, it supports through-hole mounting and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates double-sided circuit boards
• Gold-plated copper alloy contacts provide corrosion resistance and stable conductivity
• Thermoplastic polyester housing offers durability and thermal stability
• Through-hole termination ensures secure mechanical attachment to the PCB

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Consumer electronics with standardized expansion slot requirements
• Medical devices needing reliable high-density connections

Edgeboard Connectors Procurement Notes

Verify that the target application requires a dual-edge connector, as this component is not compatible with single-sided card edges. Confirm the PCB hole pattern matches the through-hole mounting style specified in the datasheet. Ensure the operating environment stays within the -40°C to +105°C range to maintain material integrity. Check for any specific flange dimensions if panel mounting constraints exist.

Edgeboard Connectors Selection Notes

Select this part when a dual-edge interface is mandatory for the system architecture. The 34-position count suits moderate density needs compared to higher-pin alternatives. Consider the 0.100" pitch for standard board layouts. Gold plating is essential for environments where oxidation could compromise contact reliability over time.

Edgeboard Connectors Part Context

This component belongs to EDAC's 391 series, which focuses on standard card edge connectors for general-purpose electronic assemblies. The series provides various pin counts and configurations to support diverse board sizes. The 391-034 variant specifically addresses applications needing a compact yet durable connection point for dual-sided PCBs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 391 series parts with identical 34-position dual-edge specifications. Verify compatibility with existing PCB footprints before swapping. Alternative manufacturers may offer similar specs but require validation of dimensional tolerances and material ratings.
