306-026-500-104

Overview

The EDAC Inc. 306-026-500-104 is a dual-edge female card edge connector featuring 52 positions with a 0.156-inch (3.96mm) pitch. Designed for panel and through-hole mounting, it utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. The housing is constructed from green polyester thermoplastic, providing robust insulation and mechanical stability. It supports board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female configuration for secure connection to non-specified double-sided circuit boards
• Gold-plated copper alloy contacts ensure durable conductivity and corrosion resistance
• Green polyester thermoplastic insulation offers high thermal stability and mechanical strength
• Panel mount design with flush flange features facilitates stable integration into chassis systems

Applications

• Industrial control system interconnects
• Medical device hardware interfaces
• Aerospace communication equipment modules
• Computing and storage server backplanes

Procurement Notes

Verify the specific contact finish thickness and material composition against the official manufacturer datasheet before finalizing procurement. Confirm that the required board thickness falls within the specified 0.054 to 0.070-inch range to ensure proper mating engagement. Check for RoHS compliance status if environmental regulations apply to your project. Ensure the selected variant matches the exact 52-position count and 3.96mm pitch requirements.

Selection Notes

Select this component when a dual-edge female interface is required for high-density applications needing a 0.156-inch spacing. Consider the operating temperature range up to 105°C for environments with moderate thermal loads. Evaluate the panel mount style against available chassis space and mounting hole configurations. Compare the gold contact finish against cost-sensitive alternatives if extreme durability is not critical for the intended duty cycle.

Part Context

This part belongs to the EDAC 306 series, which specializes in edgeboard connectors for rack and panel applications. The series is known for providing versatile interconnect solutions across computing, medical, and industrial sectors. The 306-026-500-104 specifically addresses needs for dual-sided card connections with standardized positioning and robust construction suitable for rigorous operational environments.

Replacement Considerations

Direct substitutes must match the 52-position count, 3.96mm pitch, dual-edge female gender, and panel mount style. Verify compatibility with the same board thickness range and operating temperature limits. Cross-reference pinout definitions and flange dimensions to ensure mechanical fit within existing enclosures without modification.
