305-044-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-204 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 44 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of green thermoplastic polyester, ensuring operation within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for double-sided card edge connections
• Straddle mount installation style providing secure panel attachment
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester insulation offers durability across specified temperatures

Edgeboard Connectors Applications

• Panel-mounted card edge interconnect systems
• Industrial control module interfaces
• Test and measurement equipment backplanes
• Communication hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination type, and insulation material properties. Ensure that the selected variant matches the required board thickness tolerance and mounting hole specifications for your enclosure design. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 44-position interface is required for panel-mounted applications. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Verify compatibility with the target PCB edge thickness and ensure the straddle mount style aligns with the mechanical constraints of the host chassis or panel cutout dimensions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options for diverse electronic assembly needs. The 305-044-556-204 specifically addresses applications requiring robust dual-row connectivity with panel-mount stability, distinguishing it from surface-mount or through-hole header variants within the broader product portfolio.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Verify mechanical footprint compatibility before substituting with other manufacturers' products to ensure proper fit within existing panel cutouts and mating card specifications.
