305-080-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-080-520-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 80 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector accommodates PCBs with a thickness of 1.57 mm and utilizes gold-plated copper alloy contacts for reliable signal transmission. Rated for 5 A continuous current, it employs solder pin termination for secure board attachment.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment and security
• Features gold plating on mating areas and tin plating with nickel underplating on tails
• Provides high dielectric strength with a 1800VACrms rating

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement devices needing reliable high-density interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and tail finish specifications, as variations exist within the 305 series. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure design requirements. Check RoHS compliance status against current regulatory standards for the intended market.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with an 80-position count is required. The 3.96 mm pitch suits applications where spacing constraints allow for larger connectors compared to finer pitches. Consider the 5 A current rating for power distribution needs alongside signal lines. The panel mount style is ideal for chassis-based installations rather than direct board-to-board stacking.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common electrical characteristics like the 5 A rating. The 305-080-520-504 specifically denotes the 80-position variant with dual-side access and gold contacts, distinguishing it from single-row or lower-count alternatives in the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 80 positions and 3.96 mm pitch, such as the 305-080-520-502 if different tail plating is acceptable. Verify mechanical dimensions and contact material compatibility when cross-referencing with generic industrial card edge connectors.
