305-082-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-082-556-512 is a standard card edge connector designed for vertical panel mount applications. It features 82 positions with a dual female contact configuration and a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A. The housing utilizes thermoplastic polyester insulation, providing an operating temperature range of -40°C to +105°C. This component accepts between-contact and in-contact polarizing keys and offers high dielectric strength.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Vertical panel mount installation style with solder pin termination
• Gold-plated copper alloy contacts ensure reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compatibility with required polarizing keys and board thickness specifications. Ensure that the selected variant matches the intended thermal and electrical ratings for the target application environment. Cross-reference the part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this connector when a high-density interface with 82 positions is required for vertical mounting. The 3.96 mm pitch accommodates standard PCB layouts while the 5 A current rating supports moderate power distribution. Verify that the mating card edge thickness falls within the specified tolerance range to ensure proper mechanical engagement and electrical continuity during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and configurations for diverse electronic assembly needs. The 305-082-556-512 specifically addresses applications needing a dual-row female interface with robust mechanical retention and high current carrying capacity in a compact form factor.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or keying options. Ensure any replacement maintains the same 3.96 mm pitch and vertical mounting orientation to preserve board layout integrity.
