307-026-427-104

Edgeboard Connectors Overview

The EDAC Inc. 307-026-427-104 is a standard single-edge card edge connector designed for panel mounting applications. It features 26 positions with a contact spacing of 0.156 inches (3.96 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 copper alloy contacts finished in tin plating, it utilizes a green thermoplastic polyester insulator body. This component operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A.

Edgeboard Connectors Feature Summary

• Single-edge female connector configuration with flush mount flange featuring top opening and unthreaded design
• Low profile insulator body constructed from thermoplastic polyester material
• Copper alloy contacts with tin plating for reliable signal transmission
• Panel mount installation style compatible with specified board thickness

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Test and measurement instrumentation panels
• General-purpose electronic assemblies needing single-row connectivity

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact contact plating and material specifications. Ensure that the required PCB thickness aligns with the connector's acceptance range of 0.062 inches. Confirm compatibility with the intended panel cutout dimensions due to the flush mount flange design. Cross-reference the pin count and row configuration to prevent mismatching with existing system architectures.

Edgeboard Connectors Selection Notes

Select this component when a single-edge interface with 26 positions is required for panel-mounted applications. Consider the tin-plated contacts for cost-effective solutions where high corrosion resistance is not the primary constraint compared to gold variants. Evaluate the 0.156-inch pitch requirement against the mating card edge layout. Assess the operating temperature range suitability for the specific environmental conditions of the target assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of standard card edge connectors. The series offers various position counts and mounting styles tailored for diverse electronic interconnection needs. The 307 series is characterized by its low-profile design and compatibility with standard PCB thicknesses, making it suitable for space-constrained panel installations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical positioning but different plating or housing colors, such as 307-026-427-107 or 307-026-427-112. Verify that any replacement maintains the 26-position count and 3.96 mm pitch to ensure mechanical and electrical compatibility.
