305-046-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-503 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features 46 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card configurations. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and has a continuous current rating of 5 A. It accommodates printed circuit boards with a thickness of 1.57 mm (0.062 inch). The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure board insertion
• Gold-plated contacts on copper alloy substrate for corrosion resistance
• Panel mount installation style with vertical orientation
• Thermoplastic polyester insulator body for structural stability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and housing color specifications. Confirm that the target application environment falls within the operational temperature range of -40°C to +105°C. Ensure compatibility with the nominal PCB thickness of 1.57 mm to guarantee proper mechanical fit and electrical contact integrity during assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 46-position interface is required for panel-mounted systems. The 3.96 mm pitch allows for substantial trace spacing compared to finer pitches. Consider the 5 A current rating for power distribution needs. Verify that the dual-edge configuration aligns with the card edge geometry of the mating PCB assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers a range of card edge connectors with varying position counts. The series is characterized by its robust construction and standardized dimensions. Similar models in the series include variants with different pin counts such as 305-042 or 305-050, maintaining consistent pitch and mounting characteristics across the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC part numbers 305-042-555-503 and 305-050-555-503, which share identical mechanical and electrical specifications but differ in position count. Cross-brand replacements require verification of pitch, current rating, and mounting style compatibility.
