842-050-544-107

Edgeboard Connectors Overview

The EDAC Inc. 842-050-544-107 is a high-temperature card edge connector from the 842 series, designed for through-hole mounting. It features 50 positions with a female contact type and a 0.100-inch (2.54mm) pitch. The connector utilizes gold-plated contacts on a copper alloy base, housed in a green diallyl phthalate (DAP) insulation body. It supports a current rating of 3A and operates within a temperature range of -40°C to 125°C. The flange feature includes flush mount, top opening, and an M3 threaded insert.

Edgeboard Connectors Feature Summary

• High-temperature rated construction using DAP insulation material
• Gold-plated spring-type cantilever contacts for reliable signal transmission
• Flush mount design with top opening and M3 threaded insert for secure panel attachment

Edgeboard Connectors Applications

• Industrial control systems requiring thermal stability
• High-temperature electronic assemblies
• Panel-mounted circuit board interconnections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required high-temperature specifications and flange configuration. Confirm compatibility with the target PCB thickness and mating card edge dimensions. Ensure the M3 threaded insert aligns with the mechanical mounting constraints of the application enclosure.

Edgeboard Connectors Selection Notes

Select this component when high thermal resistance is critical, as indicated by the DAP insulation and 125°C operating limit. The 0.100-inch pitch and 50-position count define the density requirements. The through-hole termination method and specific flange features must match the assembly process and mechanical housing design.

Edgeboard Connectors Part Context

This connector belongs to EDAC's 842 High Temp Series, which specializes in connectors capable of withstanding elevated temperatures compared to standard plastic insulators. The series typically employs diallyl phthalate (DAP) for superior thermal performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 842 series variants or 846 series components if different pitch or position counts are needed. Verify that substitute parts maintain the same DAP insulation material and high-temperature rating to ensure thermal compatibility.
