305-076-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-076-500-508 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features 76 positions with a dual female configuration and a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy with gold plating and utilize solder eyelet termination. Rated for 5 A continuous current, it accommodates board thicknesses between 1.37 mm and 1.78 mm. Operating within a temperature range of -40°C to +105°C, this component ensures reliable electrical connections in industrial environments.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides secure mating with double-sided card edges
• Gold-plated copper alloy contacts ensure corrosion resistance and stable conductivity
• Panel mount design with vertical orientation facilitates robust structural integration
• Solder eyelet termination offers durable mechanical attachment to printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Automotive electronics demanding stable performance under vibration
• Test and measurement instrumentation needing precise signal routing

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 76-position count and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm to ensure proper insertion force and retention. Check for any updated environmental compliance certifications such as RoHS or REACH status directly from the manufacturer's latest documentation. Ensure that the panel mounting style aligns with the mechanical constraints of the final assembly enclosure.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface is necessary for high-density signal transmission in panel-mounted configurations. The 5 A current rating supports moderate power distribution alongside data lines. Consider the vertical mounting angle if space constraints require the connector to protrude perpendicularly from the panel. Verify that the gold contact finish meets the oxidation resistance requirements for the operating environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting styles to accommodate different form factors. As a panel-mount header, it serves as a stationary interface for removable circuit cards, distinguishing it from PCB-mount receptacles that attach directly to the substrate.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 76-position count and 3.96 mm pitch. Verify that alternative suppliers offer identical contact geometry and termination types to maintain mechanical interchangeability. Ensure that any substitute part maintains the same current rating and temperature specifications for equivalent performance.
