305-052-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-052-556-508 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 52 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, providing a continuous current rating of 5 A and a dielectric withstand voltage of 1800 VACrms. The insulator body is green thermoplastic, offering an insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design suitable for space-constrained applications
• Gold-plated copper alloy contacts ensure reliable electrical performance
• Vertical panel mount style with solder lug termination

Edgeboard Connectors Applications

• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement devices needing high dielectric strength connections
• Computing hardware modules requiring polarized key acceptance

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 52-position configuration and 3.96 mm pitch before procurement. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check for RoHS compliance requirements if applicable to your manufacturing standards. Ensure that the vertical panel mount orientation aligns with your chassis design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 52 positions is required. The 3.96 mm pitch is critical for matching existing board layouts. Consider the 5 A current rating and 1800 VACrms dielectric strength for electrical safety margins. The gold plating offers superior corrosion resistance compared to tin alternatives. Verify that the polarizing key acceptance feature is necessary for your assembly process.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series is characterized by its 3.96 mm contact spacing and compatibility with 0.062 inch nominal thickness PCBs. The 305 series is widely used in industrial and commercial applications where reliable interconnection is essential. The specific model 305-052-556-508 represents a 52-position variant within this established product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-050-556-502 (50 position) and 305-054-556-278 (54 position), provided the position count difference is acceptable. Cross-series replacements require verification of pitch, board thickness, and mounting style compatibility.
