305-056-500-212

Edgeboard Connectors Overview

The EDAC Inc. model 305-056-500-212 is a standard card edge connector header featuring 56 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for vertical panel mount installation. The contacts are constructed from copper alloy with gold plating, rated for 5 A current. The housing is made of thermoplastic polyester, supporting a board thickness of 1.57 mm. It employs solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row header design for high-density signal interconnection
• Gold-plated copper alloy contacts ensure reliable conductivity
• Vertical panel mount style facilitates secure chassis integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel interfaces
• Communication equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with target PCB stack-up and mating card dimensions. Ensure that the required contact count and row configuration match the system design requirements before procurement. Cross-reference the thermal rating and current capacity with the application load profile to guarantee long-term operational reliability under expected environmental conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. The choice is driven by the need for 56 positions with gold-plated contacts to maintain signal integrity. Consider the vertical orientation and thermoplastic housing material for environmental resistance. Validate that the 5 A current rating and operating temperature range meet the specific electrical and thermal constraints of the target assembly.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles to accommodate diverse electronic packaging needs. The 305 series is characterized by its use of thermoplastic materials and standardized pitch dimensions, providing a versatile solution for connecting edge-card modules to mainboards or chassis panels in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include models such as 305-056-500-202 and 305-056-500-578, which share identical physical dimensions and electrical characteristics but may differ in ordering suffixes.
