305-086-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-086-520-558 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 86 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are gold-plated copper alloy, rated for 5 A current. The insulator body is green, low-profile plastic, suitable for panel or PCB mounting applications requiring reliable high-density interconnects.

• Accepts standard 0.062 inch thick double-sided circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring robust I/O connections
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required mounting style and flange configuration, as the 305 series offers various mechanical options. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the receiving facility has the capability to handle small component quantities if minimum order requirements apply. Cross-reference the datasheet revision date to confirm the accuracy of electrical ratings and mechanical dimensions before finalizing purchase orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with 86 positions is required for 0.062-inch thick boards. The 3.96 mm pitch provides ample spacing for high-voltage isolation needs compared to finer pitches. Consider the gold plating for environments where oxidation resistance is critical. Evaluate the mechanical mounting constraints to ensure compatibility with the chosen housing or panel cutout dimensions specified in the mechanical drawings.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in card edge connectors for demanding industrial and commercial applications. The series is characterized by its modular design, allowing for various pin counts and mounting configurations. The 305-086-520-558 specifically addresses the need for high-pin-count interfaces in space-constrained enclosures, leveraging the durability of metal shell options or the flexibility of plastic housings depending on the exact variant selected.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-086-500-201 and 305-086-520-201, though mechanical mounting differences must be verified. Alternative manufacturers may offer similar 86-position dual-edge connectors, but pin-to-pin compatibility requires strict adherence to the 3.96 mm pitch and 1.57 mm board thickness specifications. Always validate mechanical fit and electrical ratings against the original design requirements.
