305-040-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-268 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 40 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) contact spacing. The connector utilizes copper alloy contacts with gold plating and a thermoplastic insulator. It supports a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The unit accommodates printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Operating temperatures span from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features half-beam contact type for reliable signal transmission
• Includes flange characteristics for flush mounting with top opening

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standardized card edge interfaces
• Medical devices needing high-reliability vertical connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct contact plating thickness and material specifications. Confirm that the target PCB thickness falls within the 1.37 mm to 1.78 mm operational range. Check for RoHS compliance status relevant to the procurement region. Ensure the selected variant matches the required 40-position dual-row configuration for the intended application design.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount card edge connector with 40 positions is required. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm headers. Consider the 5 A current rating for power distribution needs. Verify compatibility with polarizing keys if board orientation security is critical. Ensure the thermoplastic housing meets environmental temperature requirements up to 105°C.

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 for diverse electronic assembly needs. These connectors are characterized by their durable construction and consistent electrical performance across industrial and commercial sectors. The 305 series provides a balance of mechanical stability and electrical reliability for vertical mounting scenarios.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for verified substitute part numbers with equivalent pin counts and pitches. Cross-reference dimensions to ensure mechanical fit within the existing panel cutout. Verify that alternative components maintain the same 3.96 mm spacing and dual-row layout.
