305-052-521-212

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-212 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 52 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum PCB thickness of 0.070 inches (1.78 mm). The connector utilizes female contacts made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, it employs a solder pin termination method for secure panel mounting. The housing is constructed from green thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for robust vertical panel mounting
• Gold-plated copper alloy contacts ensuring high conductivity and corrosion resistance
• Thermoplastic polyester housing offering thermal stability and mechanical strength

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• High-density electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB edge thickness limits before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate that the dual-edge design aligns with system mechanical constraints.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface with a 3.96 mm pitch is required. The dual-edge design maximizes connection density within limited panel space. Verify that the 5 A current rating meets circuit requirements. Ensure the vertical mounting style fits the enclosure geometry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors for various industrial applications. The series offers multiple position counts and termination options. The 305-052 variant specifically addresses high-density needs with its 52-position layout.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series prefix and identical 52-position count. Verify matching pitch dimensions and housing materials for direct substitution.
