305-040-500-502

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-502 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are constructed from copper alloy with gold plating, rated for 5 A continuous current. The insulator body is made of thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact integration
• Dual female contact configuration for reliable card edge engagement

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standardized card edge interfaces
• Automotive electronics assemblies needing high-current connectivity

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color specifications. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check for any regional distribution restrictions or lead time variations before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for panel mounting. Ensure the application environment supports the specified temperature range and current rating. Verify that the polarizing key options align with the system's mechanical constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations tailored for different board thicknesses and mounting styles. The 305 series is widely used in industrial and commercial applications requiring durable, high-current connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-040-520-268 for similar electrical characteristics but different termination types. Ensure mechanical dimensions and polarizing key requirements match the existing assembly design.
