345-136-520-803

Edgeboard Connectors Overview

The EDAC Inc. 345-136-520-803 is a dual-edge card connector designed for high-density board-to-board interconnections. It features 136 positions with a 0.100 inch (2.54mm) pitch, accommodating standard edge cards. The contacts are gold-plated cantilever springs housed in a green insulator, providing reliable signal transmission. This component supports top-mount opening configurations and includes a floating bobbin flange feature with a 0.116-inch diameter to ensure secure mechanical retention and alignment during insertion.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for robust board connectivity
• Gold-plated cantilever spring contacts for low insertion force and durability
• Floating bobbin flange design for enhanced alignment and retention
• High-temperature resistant green insulator material

Edgeboard Connectors Applications

• Industrial control systems requiring stable I/O connections
• Telecommunications equipment backplanes
• Embedded computing modules and carrier boards
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm plating thickness, termination style, and mounting orientation. Ensure compatibility with the target PCB footprint and card edge thickness specifications before procurement. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count dual-edge interface is required with precise alignment capabilities. The floating bobbin feature makes it suitable for applications where slight misalignment between the board and card may occur. Consider the operating temperature range and environmental conditions to ensure long-term reliability in the intended deployment scenario.
