305-012-500-578

Edgeboard Connectors Overview

The EDAC 305-012-500-578 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 12 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It supports solder lug termination and accommodates PCB thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A continuous current and 1800 VACrms, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides reliable electrical connection through gold-plated copper alloy contacts
• Features a robust thermoplastic housing suitable for high-temperature environments

Edgeboard Connectors Applications

• Industrial control systems requiring secure board-to-board connections
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing polarizable connector options

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position dual row configuration and 3.96 mm pitch. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment falls within the specified operating temperature limits of -40°C to +105°C. Check for any specific polarizing key requirements if mechanical locking is necessary for the assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms insulation voltage for circuit safety. Choose the solder lug termination style for panel mounting applications. Verify that the green thermoplastic material meets the environmental resistance needs of the deployment site.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and termination styles. The series is known for its versatility in accepting polarizing keys. Similar parts in the series include different pin counts such as 18 or 50 positions, maintaining the same pitch and general structural design for interchangeability in broader system architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 12-position dual row layout and 3.96 mm pitch. Compatible alternatives should support similar current ratings and thermal ranges. Verify that the replacement connector accepts the same polarizing key types if mechanical retention is critical to the design.
