306-026-521-102

Overview

The EDAC Inc. 306-026-521-102 is a standard card edge connector designed for dual-edge mating applications. It features 52 positions arranged in a single centerline row with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated contacts and a green insulator body constructed from thermoplastic material. It supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Single centerline row configuration for low-profile board integration
• Gold-plated contacts ensure reliable signal transmission
• Compatible with 0.062 inch nominal thickness PCBs

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard density connectors
• General-purpose electronic assemblies needing single-row connectivity

Procurement Notes

Verify the specific pin count and row configuration against the official datasheet before procurement, as variations exist within the 306 series. Confirm that the target application requires a single centerline row rather than a double-row format. Ensure the PCB design accommodates the specified 0.156-inch pitch and 0.062-inch thickness constraints to guarantee proper mechanical fit and electrical performance.

Selection Notes

Select this component when a single-row, dual-edge female connector is required for standard density applications. The 0.156-inch spacing offers a balance between pin density and manufacturing ease. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Verify compatibility with the specific PCB thickness of 0.062 inches to avoid mechanical interference during assembly.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its single centerline row design, distinguishing it from double-row variants like the 846 series. The 306 series is widely used in applications where space efficiency and standard pitch dimensions are prioritized over higher pin counts per unit length.

Replacement Considerations

Direct substitutes must match the 52-position count, single row layout, and 0.156-inch pitch. Verify that alternative components support the same 0.062-inch PCB thickness and operate within the -40°C to +105°C range. Cross-reference pinout and mounting hole specifications to ensure mechanical interchangeability.
