305-046-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-203 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 46 positions with a 3.96 mm (0.156 inch) contact spacing and dual rows of female contacts. The connector utilizes gold-plated copper alloy terminals with solder lug termination. It accommodates printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). The housing is constructed from green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified card edge applications
• Vertical panel mount style with flush mount flange feature
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation body for environmental stability

Edgeboard Connectors Applications

• Signal communication connections in modular electronic systems
• Power connection interfaces for daughter boards
• Extender board interconnections in rack and panel assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to ensure compatibility with required board thicknesses and termination styles. Confirm that the dual female contact type aligns with the mating card edge design. Cross-reference the RoHS status and material declarations with the latest datasheet documentation prior to procurement to meet regulatory requirements.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount interface is required for double-sided card edges. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical retention. Verify that the 3.96 mm pitch matches the system layout constraints and that the 46-position count satisfies the circuit density requirements without exceeding available panel space.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides engineered solutions for power and signal communication between motherboards, daughterboards, and extenders. The series is characterized by its robust construction and standardized dimensions, facilitating integration into various industrial and commercial electronic enclosures requiring reliable card-edge interfacing.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for direct substitutes. Compatible alternatives may include variations in the 305 series with different position counts or termination types, provided they maintain the same 3.96 mm pitch and panel mount form factor.
