845-047-520-104

Edgeboard Connectors Overview

The EDAC Inc. 845-047-520-104 is a high-temperature series card edge connector designed for single-edge applications. It features a 0.100-inch (2.54mm) pitch with 47 positions in a single row. The component utilizes gold-plated copper alloy contacts and a green diallyl phthalate (DAP) housing. It supports wire wrap termination and panel mount installation. The connector accommodates card thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). It operates within a temperature range of -40°C to +125°C, ensuring reliability in demanding thermal environments.

Edgeboard Connectors Feature Summary

• High-temperature capability suitable for rigorous operational conditions
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Single-row configuration with 47 positions for dense circuit board integration

Edgeboard Connectors Applications

• Industrial control systems requiring high thermal stability
• Telecommunications equipment interfaces
• Aerospace and defense electronic assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish, housing color, and termination style match the design requirements. Confirm that the target PCB or card edge thickness falls within the specified 1.37mm to 1.78mm range. Ensure the application environment does not exceed the maximum operating temperature of +125°C. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this connector when a single-row, high-temperature solution is required for non-specified single-edge cards. The 0.100-inch pitch dictates compatible PCB layout dimensions. Consider the DAP housing material for its thermal properties. Verify that wire wrap termination is compatible with the system's assembly process. Compare against the 345 series if lower temperature ratings are acceptable for cost optimization.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 Series, which specializes in high-temperature card edge connectors. The series is characterized by robust construction using diallyl phthalate materials. The 845 line serves critical applications where standard connectors may fail due to heat stress. This specific model represents a mid-range position count within the single-row product family.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 345-047-520-104 shares similar physical dimensions but has a lower temperature rating (-40°C to +105°C), making it unsuitable for direct replacement in high-temperature applications.
