305-012-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-501 is a dual-edge female card edge connector from the 305 series, designed for through-hole mounting. It features 12 positions arranged in two rows of six, with a 0.156-inch (3.96mm) pitch. The contacts are semi-bellows type made of copper alloy with gold plating. Rated for 5A continuous current and 1800VACrms insulation voltage, it operates between -40°C and 105°C. The green thermoplastic polyester housing accepts polarizing keys.

Edgeboard Connectors Feature Summary

• Dual-row configuration with semi-bellows contact design for secure board retention
• Supports between-contact and in-contact polarizing keys for alignment
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester housing provides thermal stability

Edgeboard Connectors Applications

• High-voltage circuit interconnections requiring 1800VACrms isolation
• Industrial control systems operating within extended temperature ranges
• Edgeboard connections in automated machinery
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific part number against manufacturer datasheets to confirm pin count and row configuration. Ensure compatibility with the target PCB thickness and polarizing key requirements. Check RoHS compliance status for environmental regulations. Confirm that the through-hole mounting style matches the assembly process capabilities.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. Consider the 5A current rating and high voltage insulation for power applications. Verify that the semi-bellows contact type meets the mechanical retention needs. Ensure the operating temperature range aligns with the system environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various mounting options and contact configurations. The series is known for robust construction suitable for demanding environments. Similar parts in the series may differ in position count or mounting lugs, but share the same pitch and contact material characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 12-position dual-row layout and 0.156-inch pitch. Verify that alternative connectors support the same current rating and voltage insulation. Ensure the replacement maintains the semi-bellows contact type and through-hole mounting style for mechanical compatibility.
