305-036-556-502

Edgeboard Connectors Overview

The EDAC Inc. 305-036-556-502 is a dual-row card edge connector designed for vertical panel mounting. It features 36 positions with a 0.156-inch (3.96mm) contact spacing and a 0.140-inch row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts finished with 10.0µin gold plating, it provides reliable electrical performance. The insulator body is made of polyester thermoplastic, offering a low-profile design suitable for space-constrained applications.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations. Confirm that the target application utilizes a 0.062-inch nominal PCB thickness to guarantee proper mechanical fit. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the selected variant matches the required voltage and current ratings for the intended circuit load.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for vertical panel installation. It is appropriate for designs necessitating polarizing key acceptance to prevent incorrect insertion. Choose this part for applications demanding a 5A current rating and high dielectric strength. Consider the low-profile insulator body if height constraints are critical within the enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which are standardized for use with 0.062-inch thick printed circuit boards. The series offers various position counts and termination options to support diverse electronic assembly requirements. These connectors are widely used in industries requiring durable, high-reliability interconnect solutions for modular hardware architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-036-520-502 or 305-036-556-508, depending on specific termination or flange requirements. Verify that any replacement maintains the 0.156-inch pitch and 0.062-inch board thickness compatibility. Cross-reference pin counts and row configurations to ensure functional equivalence in the existing layout.
