845-050-542-403

Edgeboard Connectors Overview

The EDAC Inc. 845-050-542-403 is a standard single-row card edge connector from the 845 High Temp Series, designed for panel mounting applications. It features 50 positions with a 2.54 mm (0.100 inch) contact spacing and supports a board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts with wire wrap termination. Constructed with a green diallyl phthalate (DAP) insulator, it operates within a temperature range of -40°C to +125°C, offering an insulation resistance of 5 GOhms and a current rating of 3 A.

Edgeboard Connectors Feature Summary

• High-temperature capability up to +125°C using DAP insulator material
• Gold-plated copper alloy contacts ensure reliable signal integrity
• Wire wrap termination style provides secure electrical connections

Edgeboard Connectors Applications

• High-temperature electronic assemblies requiring robust connectivity
• Panel-mounted interface systems utilizing single-edge boards
• Industrial control units operating in elevated thermal environments

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position configuration and wire wrap termination style. Confirm compatibility with the target PCB thickness of 1.57 mm and ensure the application environment stays within the specified -40°C to +125°C operational range. Check for any specific RoHS compliance requirements if applicable to your manufacturing standards.

Edgeboard Connectors Selection Notes

Select this component when high-temperature stability is critical for the assembly. The wire wrap termination requires compatible wiring infrastructure. Ensure the mating card edge thickness aligns with the 1.57 mm specification to maintain proper contact engagement. Consider the straight panel mount orientation for integration into the chassis design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 845 Series, which specializes in high-temperature card edge solutions. The series is characterized by the use of diallyl phthalate insulators to withstand thermal stress. Variations within the series differ primarily in position count and termination type, such as solder pin alternatives found in other SKUs like the 845-059-524-408.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and termination but different position counts, such as 845-015-542-458 or 845-046-524-108. Verify that any replacement maintains the 2.54 mm pitch and wire wrap termination to ensure mechanical and electrical compatibility.
