305-052-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-207 is a standard card edge connector from the 305 series, designed for dual female connections with 52 positions. It features a 0.156-inch (3.96 mm) pitch and utilizes gold-plated copper alloy contacts. The unit is constructed with a green thermoplastic polyester insulator and supports panel mounting in a vertical orientation. It accommodates board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm).

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card applications.
• Gold-plated copper alloy contacts ensure reliable signal transmission.
• Vertical panel mount design with solder pin termination.
• Green thermoplastic polyester housing provides structural stability.

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces.
• Telecommunications equipment utilizing standardized modular boards.
• Test and measurement devices needing high-density vertical connections.
• Automotive electronics assemblies with specific form factor requirements.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm contact plating and housing color specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm that the vertical panel mount style aligns with the mechanical enclosure design. Check RoHS compliance status against current regulatory requirements for the destination market.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. The 52-position count suits applications needing moderate density without excessive height. The vertical orientation is optimal for space-constrained panels where horizontal clearance is limited. Gold plating is necessary for environments demanding corrosion resistance and low contact resistance.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting styles. The series is characterized by its use of thermoplastic polyester insulation and copper alloy contacts. It serves as a standard interface solution for industrial and commercial electronic modules requiring durable card edge connectivity.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-048-520-207 or 305-040-520-268 if position count adjustments are needed. Verify that alternative parts maintain the same 3.96 mm pitch and dual-edge female configuration to ensure mechanical and electrical compatibility.
