305-042-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-207 is a standard card edge connector featuring 42 positions with a 3.96 mm (0.156 inch) pitch. It is designed for dual-edge board insertion and utilizes female contacts. The component supports printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a continuous current rating of 5 amps and an insulation voltage of 1800VACrms. The housing material is green thermoplastic, and the contacts are gold-plated copper alloy.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact panel mounting applications
• Utilizes gold plating on mating areas to ensure reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card interfaces
• Industrial control systems utilizing polarized card edge connections
• High-voltage isolation environments within modular hardware architectures

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and termination style. Confirm that the target application requires dual-edge compatibility rather than single-edge variants. Ensure the PCB thickness falls within the specified acceptance range for proper mechanical retention. Check RoHS compliance status against current regulatory requirements for the destination market.

Edgeboard Connectors Selection Notes

Select this model when a 42-position dual-edge interface is required with a 3.96 mm pitch. The 5A current rating suits moderate power distribution needs. Verify that the 1800VACrms insulation rating meets the system's electrical safety standards. Consider the availability of compatible polarizing keys if board orientation security is critical for the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305 series is characterized by its robust construction and compatibility with standard PCB thicknesses. It serves as a foundational interconnect solution for modular electronic designs requiring durable panel-mount interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-042-520-202 and 305-042-500-504. These alternatives share identical mechanical dimensions and pitch but may differ in contact termination type or plating specifications. Cross-reference the datasheet to ensure functional equivalence before substitution.
