305-040-500-558

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-558 is a standard card edge connector from the 305 series, designed for dual-row female connections with a 40-position configuration. It features a 3.96 mm (0.156 inch) contact spacing and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts and thermoplastic insulation, rated for 5 A current at temperatures ranging from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy terminals ensure reliable conductivity
• Thermoplastic insulator body provides structural stability
• Panel mount installation style supports vertical orientation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 40-position count and 3.96 mm pitch before ordering. Confirm panel mounting requirements align with the vertical installation style. Ensure the host PCB thickness falls within the specified tolerance range for proper engagement. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for thick PCB applications around 1.57 mm. The 3.96 mm pitch suits high-power or signal-heavy designs needing robust mechanical retention. Consider the gold plating for corrosion resistance in demanding environments. Verify that the panel mount form factor fits the enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its low-profile insulator body and standardized spacing. Similar parts in the family include variants with different pin counts such as 305-036-500-558 or 305-048-500-558, maintaining consistent electrical and mechanical specifications across the lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-036-500-558 and 305-048-500-558, provided the position count difference is acceptable. Cross-brand replacements require matching the 3.96 mm pitch, 1.57 mm board thickness, and dual-row female interface.
