305-024-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-024-521-501 is a dual-edge female card edge connector designed for through-hole mounting. It features 24 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The insulator is green thermoplastic polyester, and the connector accepts card thicknesses between 0.054" and 0.070" (1.37mm to 1.78mm).

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment.
• Provides a continuous current rating of 5A and withstands 1800VACrms dielectric voltage.
• Utilizes half-beam contact type for reliable signal transmission.

Edgeboard Connectors Applications

• Medical interconnect systems requiring durable connections.
• Agricultural technology equipment operating in harsh environments.
• General industrial control boards utilizing standard card edge interfaces.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct pin count, contact finish, and flange configuration. Confirm that the target PCB footprint matches the 0.156-inch pitch dimensions. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the selected variant supports the required operating temperature range of -40°C to 105°C.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided connection with 24 pins is required for non-specified cards. The 0.156-inch spacing accommodates standard board layouts. Consider the 5A current capacity for power distribution needs. Verify compatibility with polarizing key requirements if mechanical locking is necessary for the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting options. The 305-024-521-501 specifically addresses applications needing robust connectivity with gold-plated contacts for corrosion resistance and low contact resistance.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-014-521-501 and 305-016-521-501 for lower pin counts, or 305-030-521-501 for higher density. Ensure any replacement maintains the 0.156-inch pitch and dual-edge female configuration.
