387-032-521-212

Edgeboard Connectors Overview

The EDAC Inc. 387-032-521-212 is a dual-edge female card edge connector from the 387 Series, designed for vertical through-hole mounting. It features 32 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The contacts are made of copper alloy with a gold plating thickness of 10.0 microinches. The housing is black thermoplastic polyester, rated for operation from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration supports high-density signal routing on both sides of the circuit board.
• Cantilever contact design ensures reliable mating force and secure connection stability.
• Gold-plated terminals provide corrosion resistance and maintain consistent electrical conductivity over time.

Edgeboard Connectors Applications

• Industrial control systems requiring robust peripheral interconnects
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the target PCB stack-up accommodates the specified 0.156-inch pitch and dual-edge geometry. Confirm thermal management requirements align with the -40°C to +105°C operating range. Ensure surface finish compatibility with the gold-plated cantilever contacts during assembly processes.

Edgeboard Connectors Selection Notes

Select this component when dual-sided connectivity is required for a 32-position interface. The 0.156-inch spacing suits applications needing wider trace clearance compared to finer pitches. Verify that the board thickness falls within the 0.054 to 0.070-inch window for proper retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 Series, which provides standardized card edge solutions. The series offers various row counts and edge configurations to support diverse modular electronic designs. The 387-032 variant specifically addresses mid-range density needs in industrial and commercial hardware.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 387 family that share the 0.156-inch pitch and dual-edge layout. Ensure substitute models match the 32-position count and through-hole termination style for direct mechanical integration.
