305-026-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-026-556-512 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 26 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it utilizes a thermoplastic polyester insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with semi-bellows contact type for secure board engagement
• Low-profile insulator body constructed from green thermoplastic polyester
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount installation style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Test and measurement instrumentation with high-density interconnect needs

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact physical dimensions and mounting variations. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before procurement. Confirm that the required current rating of 5 A aligns with the system design specifications. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting. The 26-position count suits applications needing moderate density without excessive footprint. Verify that the operating temperature range of -40°C to +105°C meets environmental conditions. Consider the semi-bellows contact type for its mechanical retention capabilities on standard thickness boards.
