305-030-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-030-555-558 is a standard card edge connector from the 305 series, designed for reliable electrical interconnection in electronic assemblies. It features a dual row configuration with 30 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes gold-plated copper alloy contacts to ensure signal integrity. Rated for 5 A continuous current, it employs a solder lug termination style for secure panel mounting. The insulator body is constructed from thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for precise alignment
• Features a low-profile insulator body for compact assembly integration
• Utilizes gold-plated copper alloy contacts for enhanced conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic interface systems
• Industrial control board interconnections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, termination type, and flange characteristics. Ensure compatibility with the target PCB thickness of 0.062 inches and required polarizing key configurations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, panel-mount solution with polarizing key acceptance is required. The 305 series offers high current capacity and durable construction suitable for demanding environments. Confirm that the application requires a dual-row layout and solder lug termination for proper mechanical stability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are engineered for high-reliability applications. The series is characterized by its ability to accept polarizing keys and its standardized dimensions, ensuring interchangeability within compatible system designs while maintaining strict electrical performance standards.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-030-500-558 or 305-030-556-558 if different termination styles or flange options are needed. Verify that substitute parts maintain the same 0.156-inch pitch and 30-position count.
