305-044-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-507 is a standard card edge connector from the 305 Series, designed for dual-edge PCBs. It features 44 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A current at +105°C maximum operating temperature, it supports panel mounting via threaded inserts. The unit complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-row contact configuration for high-density interconnection
• Gold-plated mating area ensures reliable signal transmission
• Thermoplastic polyester housing provides thermal stability
• Panel mount design with integrated flange features

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating thickness and terminal type. Ensure the selected variant matches the required board thickness range of 1.37 mm to 1.78 mm. Confirm compliance with RoHS3 directives if environmental regulations apply to the assembly process. Cross-reference the part number with the latest EDAC series ordering guide to avoid specification mismatches.

Edgeboard Connectors Selection Notes

Select this component when a robust, dual-edge connection is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch accommodates larger trace spacing compared to finer pitches. Verify that the application environment stays within the -40°C to +105°C operational range. Consider the panel mounting style if space constraints on the PCB surface are critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options including panel and PCB styles. The series is characterized by its durable construction and standardized dimensions. Similar parts in the series vary by position count and mounting hardware, such as the 305-050 or 305-080 variants.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series connectors with identical 44-position dual-row layouts. Verify mechanical compatibility with existing flange holes and thread sizes before replacement.
