305-072-520-258

Edgeboard Connectors Overview

The EDAC 305-072-520-258 is a standard card edge connector receptacle featuring 72 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts with a solder termination type for secure PCB mounting. Designed for vertical installation, it supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Provides high insulation resistance rated at 5 GOhms

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal configuration and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the required polarizing key style matches the system design requirements. Check manufacturer documentation for updated RoHS compliance status prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 72-position interface is required for thick PCB applications. The 3.96 mm pitch offers mechanical stability for larger connectors. Verify that the 5 A current rating meets the electrical load requirements of the application. Consider the vertical mounting orientation for panel or chassis integration constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to handle relatively thick PCBs compared to fine-pitch alternatives. The 305 series provides a balance of mechanical durability and electrical performance for general-purpose interconnect needs.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for variations in row count or pitch. Verify that substitute components maintain the same 1.57 mm PCB thickness tolerance and 3.96 mm spacing.
