305-042-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-201 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features a dual female configuration with 42 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are made of copper alloy with gold plating, providing a continuous current rating of 5 A. The housing is constructed from green thermoplastic polyester, ensuring durability within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Features half-beam contact type for reliable signal transmission
• Includes flange characteristics with top opening for flush mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment with high-density requirements
• Automotive electronics applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and flange specifications. Confirm that the selected variant meets the necessary insulation resistance and voltage ratings for the intended application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the mating printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the 5 A current rating and 1800 VACrms dielectric strength when evaluating electrical performance needs for the system design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their durable thermoplastic housings and gold-plated copper alloy contacts. The series offers various position counts and mounting options, catering to diverse electronic assembly needs. The 305-042 model specifically provides a 42-position interface, balancing density with mechanical stability for professional-grade hardware implementations.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange styles. Verify that any alternative maintains the same 3.96 mm pitch and dual female contact configuration to ensure mechanical and electrical interchangeability without redesigning the host PCB.
