305-042-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-502 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 42 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a half-beam termination type, secured via solder lug end connections. It supports board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring durability in industrial environments.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides reliable signal transmission for double-sided card edge boards.
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance over time.
• Solder lug termination style facilitates secure panel mounting and robust mechanical stability.
• Thermoplastic polyester insulation offers high dielectric strength and thermal resilience.

Edgeboard Connectors Applications

• Industrial control systems requiring durable panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Automotive electronics modules needing high-reliability connections
• Test and measurement instrumentation hardware

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and termination specifications. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the panel cutout dimensions align with the specified 3.25 mm diameter opening. Cross-reference the RoHS status if environmental compliance is mandatory for the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications where spacing between signals allows for larger connectors. Consider the half-beam contact design for insertion forces compatible with the mating card edge. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination styles to accommodate different board densities. The 305-042 variant specifically addresses mid-density requirements with a dual-row layout, balancing space efficiency with connection reliability in compact enclosures.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 42-position dual female configurations and matching 3.96 mm pitch. Verify that alternative models share the same solder lug termination and panel mount orientation. Ensure any replacement maintains the same contact material and plating specifications for electrical continuity.
