305-064-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-064-555-203 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features a dual female configuration with 64 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a half-beam termination type, soldered via pins. It accommodates printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Provides a 1800 VACrms dielectric voltage rating for reliable insulation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density interconnects
• Industrial control systems utilizing double-sided card edge PCBs
• Test and measurement equipment needing robust vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations within the 305 series. Confirm that the target application requires a dual-edge female connector compatible with the specified 0.156-inch pitch. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount interface is required for double-sided cards. The 64-position count suits applications needing moderate signal density. Verify that the PCB thickness falls within the 1.37 mm to 1.78 mm range to ensure proper mechanical retention and electrical contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing a common 0.156-inch contact spacing. The 305-064-555-203 specifically denotes a 64-position dual female variant with gold contacts and a green thermoplastic housing.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305-series parts for different position counts or row configurations. Verify compatibility with mating card edge PCBs before substitution. No direct cross-manufacturer equivalents are documented in the provided source material.
