305-066-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-203 is a dual-edge female card edge connector designed for through-hole panel mounting. It features 66 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The contacts are made of copper alloy with a gold plating finish, suitable for reliable signal transmission. The unit accommodates board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure connection to non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure durable conductivity and corrosion resistance
• Through-hole termination method provides robust mechanical stability on printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm flange dimensions and terminal styles. Ensure compatibility with target PCB hole sizes and panel cutouts. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is necessary for dual-edge card applications. The 0.156-inch pitch allows for broader trace routing compared to finer pitches. Verify that the housing material and operating temperature range meet the environmental demands of the intended deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various pin counts and termination options tailored for diverse electronic assembly needs. The 305 series is recognized for its versatility in connecting edgeboards to main system boards in rugged environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305-series variants such as 305-066-521-202 or 305-066-521-508 for alternative flange or termination configurations. Ensure any substitute maintains identical electrical ratings and mechanical footprint constraints.
