306-017-520-178

Edgeboard Connectors Overview

The EDAC Inc. 306-017-520-178 is a standard card edge connector receptacle from the 306 Series. It features 34 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge card configurations. The connector utilizes gold-plated copper alloy contacts rated for 5 A current and is designed for through-hole solder termination. It accommodates a board thickness of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge contact configuration for robust signal transmission
• Gold-plated terminals ensure reliable conductivity
• Thermoplastic polyester insulation provides thermal stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and flange mounting requirements against the mechanical drawing before procurement. Confirm that the target PCB thickness aligns with the specified 1.57 mm tolerance. Ensure the soldering process parameters are compatible with the through-hole termination style and operating temperature ratings defined in the official datasheet.

Edgeboard Connectors Selection Notes

Select this model when a high-density 34-position interface is required for dual-edge cards. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Consider the green thermoplastic housing for applications requiring standard industrial environmental resistance and verified thermal performance up to 105°C.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, serving as a foundational interconnect solution for various electronic assemblies requiring secure board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the same 306 Series family, such as 306-010-520-178 or 306-012-520-178, if different position counts are acceptable. Verify that any substitute maintains the identical 3.96 mm pitch and dual-edge contact geometry to ensure mechanical compatibility.
