305-028-555-202

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-202 is a standard card edge connector header featuring a dual-row configuration with 28 positions. It utilizes a 3.96 mm (0.156 inch) contact pitch and a 3.56 mm row spacing. Designed for vertical panel mount installation, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, the insulator body is made of thermoplastic polyester, providing stability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination type, and mounting variations. Ensure compatibility with the target PCB thickness and mating card dimensions before procurement. Cross-reference the component code with the latest EDAC series documentation to avoid discrepancies in physical dimensions or electrical ratings.

Edgeboard Connectors Selection Notes

Select this component when a robust dual-row connection is required for thick PCBs up to 1.57 mm. The 3.96 mm pitch offers ample spacing for high-current applications rated at 5 A. Consider the vertical panel mount orientation for structural support in rack-mounted systems. Verify that the gold plating meets the environmental requirements for the intended operational lifespan.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in heavy-duty card edge connectors. The series provides various position counts and mounting options for industrial-grade applications. The 305-028-555-202 variant specifically addresses needs for moderate-density connections requiring high mechanical durability and reliable electrical performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or termination styles. Verify that any alternative maintains the 3.96 mm pitch and 1.57 mm board thickness acceptance to ensure mechanical fit.
