842-112-544-212

Edgeboard Connectors Overview

The EDAC Inc. part number 842-112-544-212 is a dual-edge female card edge connector designed for high-reliability applications. It features 112 positions with a contact spacing of 0.100 inches (2.54 mm) and a row spacing of 0.200 inches (5.08 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with a copper alloy contact material and gold plating, it utilizes a thermoplastic insulator body. This component supports vertical panel mount installation and offers a robust mechanical interface for secure board retention.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration providing 112 connection points across two rows
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• High-profile insulator body accommodates standard 0.062-inch thick PCBs
• Panel mount design with vertical orientation for stable structural integration

Edgeboard Connectors Applications

• Industrial control systems requiring durable interconnect solutions
• Telecommunications equipment needing high-density signal routing
• Automotive electronics utilizing standardized board interfaces
• Test and measurement instrumentation demanding precise alignment

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact insulation color and flange specifications, as variations exist within the 842 series. Confirm that the target application requires a dual-edge female receptacle rather than a single-row or male variant. Ensure the PCB thickness falls within the acceptable range of 0.062 inches to guarantee proper mechanical engagement and electrical contact pressure during assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 112-position interface is required with a 0.100-inch pitch. The dual-edge design is suitable for applications necessitating increased pin count without expanding the footprint significantly. Consider the panel mount style if the connector serves as a fixed interface point. Verify compatibility with the mating card's edge thickness and plating requirements to ensure long-term reliability in the intended operating environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 842 series, which specializes in standard card edge connectors with a 0.100-inch contact spacing. The series is characterized by its versatility in accommodating various board thicknesses and offering multiple mounting options. The 842 series is widely used in general-purpose electronic assemblies where reliable, cost-effective interconnection is prioritized over specialized high-speed or high-power requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 842-062-544-212 for reduced position counts. Cross-series alternatives may require verification of pitch and row spacing compatibility. Always validate mechanical dimensions and electrical ratings before substituting with components from different manufacturers or series.
