305-054-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-503 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features 54 positions across two rows with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contact plating is gold over copper alloy, and the housing is constructed from thermoplastic material. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified board types
• Low-profile insulator body design
• Solder lug termination style for secure panel installation

Edgeboard Connectors Applications

• Industrial control panel interconnections
• Vertical backplane connections
• High-density signal routing in electronic enclosures

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required board thicknesses and termination styles. Confirm that the thermoplastic housing material meets environmental requirements for the intended operating temperature range. Cross-reference the 54-position count and dual-row layout with system mechanical constraints before procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided card edge applications. Ensure the host PCB thickness aligns with the 1.57 mm nominal specification. Consider the 5 A current rating and gold-plated contacts for reliable signal integrity in industrial environments requiring robust mechanical stability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options, all sharing common interface dimensions such as the 3.96 mm pitch. The 305-054-520-503 variant specifically addresses high-pin-count needs with a dual-edge female configuration suitable for rigid panel-mounted assemblies.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 54 positions and 3.96 mm pitch, such as 305-054-520-502 or 305-054-556-278, provided the termination style and housing material specifications are verified against the original design requirements.
