305-082-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-504 is a dual female card edge connector designed for panel and through-hole mounting. It features 82 positions arranged in two rows with a contact spacing of 0.156 inches (3.96mm) and a row spacing of 0.140 inches (3.56mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contact materials are copper alloy with gold plating, ensuring reliable electrical performance.

Edgeboard Connectors Feature Summary

• Dual female configuration with half-bellows contact type for secure board retention
• Low profile insulator body constructed from thermoplastic polyester
• Gold-plated contacts provide corrosion resistance and stable signal transmission
• Flange feature supports flush mounting with top opening and no thread

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment interfaces demanding reliability
• Agricultural technology hardware operating in harsh environments
• General-purpose electronic assemblies utilizing standard card edge PCBs

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct pin count and termination style. Confirm RoHS compliance status if required by project specifications. Check datasheet for mating board thickness tolerances to guarantee proper fit. Ensure storage conditions maintain contact integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with 82 pins is necessary. The 0.156-inch pitch accommodates standard board layouts. Consider the through-hole soldering requirement for permanent installation. Evaluate the low-profile design against spatial constraints within the enclosure.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various pin counts and configurations. The series is characterized by durable construction suitable for demanding applications. Other variants in the series differ primarily in position count and specific flange dimensions while maintaining consistent interface standards.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 82-position dual female specification and 0.156-inch pitch. Verify mechanical compatibility with existing panel cutouts and board thickness requirements. Cross-reference manufacturer catalogs for equivalent series connectors with identical termination methods.
