837-054-542-807

Edgeboard Connectors Overview

The EDAC Inc. 837-054-542-807 is a dual-edge female card edge connector from the 837 series, designed for high-temperature applications. It features 54 positions with a 0.156-inch (3.96mm) contact spacing and accepts board thicknesses of 0.054 to 0.070 inches. The connector utilizes copper alloy cantilever contacts with a 10.0µin gold finish and terminates via wire wrap. Constructed with green diallyl phthalate insulation, it supports through-hole mounting and operates within a temperature range of -40°C to 125°C.

• Dual-edge female configuration for secure connection to double-sided circuit boards
• High-temperature rated design suitable for demanding operational environments
• Wire wrap termination method ensures reliable electrical connections
• Gold-plated cantilever contacts provide durable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment infrastructure
• Automotive electronic modules
• Aerospace and defense instrumentation
• Medical device hardware assemblies

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to ensure correct contact count and termination style. Confirm that the target application requires dual-edge connectivity rather than single-edge variants. Check RoHS compliance status against specific project requirements. Ensure PCB layout accommodates the specified 0.156-inch pitch and board thickness constraints for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when dual-side board insertion is required for space-constrained designs. The 54-position count suits complex signal routing needs. Consider the wire wrap termination if manual assembly or reworkability is prioritized over surface mount alternatives. Validate thermal performance against the 125°C maximum operating limit for the intended environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 837 High Temperature Series, which offers various position counts and edge configurations. The series is characterized by its use of diallyl phthalate insulation and gold-plated copper alloy contacts. It serves as a standard solution for reliable card-to-board connections in harsh conditions where stability and durability are critical.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 837-series models for different pin counts or single-edge variants. Verify compatibility with existing PCB footprints before substitution. Ensure replacement parts maintain the same wire wrap termination and high-temperature rating specifications.
