305-032-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-204 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 32 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm. Contact surfaces are gold-plated copper alloy, providing a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Vertical panel mount design with solder lug termination for robust mechanical stability
• Dual-edge female contact interface compatible with non-specified double-sided cards

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge interfaces
• Panel-mounted electronic modules needing high insulation resistance
• Equipment operating within extreme temperature environments (-40°C to +105°C)

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and insulator material variations. Ensure compatibility with required polarizing key types before procurement. Confirm RoHS compliance status through manufacturer datasheets as regulatory requirements may vary by production batch.

Edgeboard Connectors Selection Notes

Select this component when vertical panel mounting is required for dual-edge card connections. The 3.96 mm pitch suits standard industrial PCB layouts. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the 5 A current rating and 1800 VACrms dielectric strength for circuit safety margins.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles. The 305 series is characterized by its robust construction and ability to accommodate polarizing keys, distinguishing it from basic header-only designs in the broader connector market.

Edgeboard Connectors Replacement Considerations

Consult EDAC Inc. directly for verified substitute part numbers. Cross-reference pitch, position count, and termination style. Generic equivalents may lack polarizing key compatibility or identical thermal ratings.
