305-070-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-558 is a standard card edge connector designed for panel mounting applications. This component features a dual-edge female configuration with 70 positions, providing robust connectivity for high-density circuit board interfaces. The connector utilizes a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for a current capacity of 5 A, this vertical header supports an operating temperature range from -40°C to +105°C.

• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance.
• Low-profile insulator body facilitates compact integration within constrained panel spaces.
• Vertical panel mount style ensures secure mechanical attachment and precise alignment.

Edgeboard Connectors Applications

• Industrial control systems requiring reliable I/O connections
• Telecommunications equipment interface modules
• Automotive electronics testing fixtures
• Medical device internal board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin configuration and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the dual-edge female specification matches the mating card requirements. Check regional availability as distribution status may vary by location. Validate RoHS compliance documentation if required for your specific manufacturing standards.

Edgeboard Connectors Selection Notes

Select this model when a 70-position dual-edge interface is required for panel-mounted assemblies. The 3.96 mm pitch suits applications needing wider spacing between contacts compared to standard 2.54 mm headers. Consider the 5 A current rating for power distribution needs alongside signal lines. The vertical orientation is ideal for direct panel insertion. Ensure the mating card edge thickness aligns with the 0.062 inch specification for proper retention.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations to support diverse electronic assembly needs. The 305 series is characterized by its low-profile design and reliable gold-plated contacts. It serves as a foundational interconnect solution for connecting daughter cards to backplanes or mainboards in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts. Verify that any substitute maintains the 3.96 mm pitch and dual-edge female topology. Ensure mechanical dimensions match the existing panel cutout and mounting constraints. Confirm electrical ratings meet or exceed the original 5 A requirement.
