305-032-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-208 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 32 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The unit provides a continuous current rating of 5 A and supports an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body made of thermoplastic material
• Utilizes solder lug termination for robust panel mounting
• Supports dual-edge card insertion for high-density interconnect applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing standardized card edge modules
• Test and measurement instrumentation needing reliable signal routing
• Automotive electronics assemblies demanding high current capacity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations within the 305 series. Ensure compatibility with existing panel cutouts and polarizing key requirements before procurement. Confirm that the target PCB thickness aligns with the specified 1.57 mm nominal dimension to guarantee proper mechanical engagement and electrical performance during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 32-position interface with 3.96 mm spacing is required for vertical panel mounting. Consider the 5 A current rating and gold-plated contacts for applications involving moderate power or sensitive signal lines. Verify that the host system accommodates the necessary polarizing key slots and that the operating temperature range meets environmental specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and spacing options to accommodate different board densities. The 305-032 variant specifically addresses mid-density requirements while maintaining the structural integrity and electrical reliability characteristic of the broader product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 32-position layouts and 3.96 mm pitch, such as 305-032-500-204 or 305-032-555-208, provided they meet identical mechanical and electrical constraints.
