305-044-500-268

Edgeboard Connectors Overview

The EDAC 305-044-500-268 is a standard card edge connector featuring 44 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and supports a nominal printed circuit board thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts with a solder pin termination type for secure electrical connection. Designed for panel mount installation, it offers a vertical orientation and maintains a continuous current rating of 5 A. The insulator body is constructed from thermoplastic material, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure mating alignment
• Features a low profile insulator body designed for compact panel mounting applications
• Provides high insulation resistance of 5 GOhms for signal integrity

Edgeboard Connectors Applications

• Interface connections for dual female card edge assemblies
• Panel-mounted electronic hardware requiring polarized keying options
• Industrial control systems utilizing standard thickness PCBs

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact finish thickness and material specifications. Ensure compatibility with the intended polarizing key configuration, as the series supports both between-contact and in-contact variants. Confirm that the target application requires the specified 3.96 mm pitch and 1.57 mm board thickness tolerance before procurement.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 44 positions is required for vertical panel mounting. It is suitable for designs needing gold-plated contacts and support for polarizing keys to prevent misalignment. Consider the 5 A current rating and thermoplastic housing properties for environmental suitability. Verify that the system architecture accommodates the standard 0.156 inch spacing constraint.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction and compatibility with various polarizing key configurations. It serves as a reliable interconnection solution for modular electronic systems where secure panel mounting and precise board alignment are critical operational requirements.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the identical 44-position count, 3.96 mm pitch, and dual-row configuration. Verify mechanical compatibility regarding panel mount dimensions and polarizing key acceptance capabilities.
