305-050-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-508 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 50 positions arranged in two rows, providing a total of 100 contact points. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm. Constructed with copper alloy contacts featuring gold plating and a thermoplastic polyester insulator, it supports a continuous current rating of 5 A and withstands voltages up to 1800 VACrms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card types for versatile interface compatibility.
• Vertical panel mount style with flange features including flush installation and top opening for secure chassis integration.
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Thermoplastic polyester insulation provides high dielectric strength and thermal stability.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing high-voltage isolation
• Embedded computing modules requiring vertical board-to-board connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, contact material, and termination type. Ensure the selected variant matches the required PCB thickness tolerance and panel mounting dimensions. Confirm RoHS compliance status if restricted substances are mandated by the target application environment.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for dual-edge cards with a 3.96 mm pitch. Consider the 5 A current rating and 1800 VACrms voltage capability for high-power or high-isolation needs. Verify that the thermoplastic polyester housing meets the thermal requirements of the operating environment, specifically the -40°C to +105°C range.
