305-042-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-268 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 42 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it provides a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is made of green thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body design for compact integration
• Utilizes half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement devices needing high-reliability connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix '555' corresponds to the intended contact termination style and insulation color before ordering. Confirm compatibility with the target PCB's nominal thickness of 0.062 inches to ensure proper mechanical fit. Cross-reference the official EDAC datasheet for the complete electrical specifications and environmental ratings to validate suitability for the intended operating conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 42 positions is required for vertical panel mounting. Ensure the application environment supports the specified temperature range and voltage ratings. Consider the availability of polarizing keys if board orientation security is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their .156 inch contact spacing. The series offers various position counts and termination options to accommodate different board designs. The 305-042 variant specifically addresses needs for higher density connections within a single module footprint.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing, such as the 305-042-520-202 or 305-042-500-504, provided the termination style matches the assembly requirements.
