305-032-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-202 is a standard card edge connector from the 305 series, designed for dual-edge female board-to-board or backplane applications. It features 32 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm), falling within the operational range of 0.054 to 0.070 inches. Constructed with copper alloy contacts featuring gold plating and a thermoplastic polyester insulator, it ensures reliable signal transmission. Rated for 5 A current at +105°C maximum operating temperature, this vertical panel-mount header utilizes solder lug termination for secure PCB attachment.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration accommodates non-specified double-sided card edge PCBs
• Low-profile insulator body constructed from thermoplastic polyester for compact integration
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance
• Vertical panel-mount design with solder lug termination ensures rigid mechanical stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment utilizing standardized card edge modules
• Test and measurement instrumentation needing high-density signal routing
• Automotive electronics assemblies demanding reliable vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before ordering. Confirm compatibility with the target PCB thickness, which must fall between 0.054 and 0.070 inches for proper engagement. Ensure the application environment remains within the specified -40°C to +105°C operating temperature range. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate that the solder lug termination method aligns with the manufacturing process capabilities of the host circuit board.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for vertical panel mounting with a 3.96 mm pitch. The 32-position count suits moderate density applications where space efficiency is prioritized over high pin counts. Consider the thermoplastic insulation material for general-purpose environments rather than extreme chemical exposure scenarios. The gold plating offers durability for repeated insertion cycles typical in modular system designs. Evaluate the 5 A current rating against the total load requirements of all active channels simultaneously connected through the interface.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, a line of standard card edge connectors characterized by their low-profile design and versatile mounting options. The series supports various position counts while maintaining consistent 3.96 mm spacing across models. These headers are engineered for industrial-grade reliability, featuring robust copper alloy contacts and durable polymer insulators. The 305 series is widely utilized in sectors requiring standardized, interchangeable electronic modules with secure mechanical locking via flanges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC part numbers such as 305-024-556-202 and 305-050-556-202, which share identical mechanical dimensions and electrical characteristics but differ in position count. Cross-series replacements like the 315 or 355 series may offer similar functionality but require verification of flange dimensions and mating force specifications to ensure mechanical compatibility.
