305-026-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-507 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 26 positions in a dual female configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes gold-plated copper alloy contacts terminated via solder pins. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodating non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount installation with vertical orientation
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Test and measurement equipment utilizing dual-edge card modules
• Telecommunications infrastructure with high-reliability requirements
• Automotive electronics assemblies needing secure board connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 26-position count and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check for RoHS compliance status if environmental regulations apply to the assembly process. Ensure the supplier provides official datasheets to validate electrical ratings and material specifications against project requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel mounting. The 5 A current rating and wide operating temperature range suit demanding environments. Consider the availability of polarizing key options if board alignment is critical. Verify that the solder pin termination method aligns with the manufacturing assembly process and that the green insulator body meets aesthetic or identification needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and row configurations. Similar models include the 305-038-520-502 and 305-050-521-507, differing primarily in position count and specific housing variations. The series is characterized by its low-profile insulator body and consistent 3.96 mm contact spacing across variants.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-038-520-502 and 305-050-521-507, though these differ in position count. Cross-series replacements may require verification of mating dimensions and electrical ratings. Ensure any alternative maintains the 3.96 mm pitch and dual-edge female configuration for functional equivalence.
