305-026-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-558 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 26 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it utilizes a green thermoplastic insulator body. The connector supports panel mounting with vertical orientation and solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Vertical panel mount design with flush flange features
• Thermoplastic insulator body provides structural stability

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card interfaces
• Industrial control systems utilizing standardized card edge modules
• Test and measurement equipment needing robust vertical interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 26-position count and 3.96 mm pitch specifications before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure the selected variant includes the necessary threaded insert features for the intended mounting application.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm spacing is required for vertical panel installation. The 26-position count suits applications needing moderate I/O density within a compact footprint. Consider the gold plating for corrosion resistance in demanding environments. Verify that the thermoplastic housing material meets the thermal requirements of the operating range.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting options. The 305-026-555-558 specifically addresses needs for dual-edge connections with a 26-pin configuration. Similar parts in the series include different pin counts such as the 305-048 or 305-080 variants, allowing for scalable design solutions within the same family architecture.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 26-position count, 3.96 mm pitch, and dual-edge female interface. Verify that any replacement part supports the same 1.57 mm PCB thickness and vertical panel mounting style. Ensure the contact material and plating meet or exceed the original specifications for electrical performance.
