305-048-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-204 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 48 positions with a 0.156-inch (3.96 mm) pitch and supports board thicknesses of 0.054 to 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and half-waffle contact types. It employs solder pin termination for panel mount installation and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card applications
• Gold-plated copper alloy contacts ensure reliable conductivity
• Panel mount design with through-hole solder termination
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Automotive electronics modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB card thickness range of 1.37 mm to 1.78 mm. Confirm that the panel mount style aligns with the mechanical enclosure design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 48-position interface is required for dual-edge cards. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Consider the vertical mounting orientation and the need for gold-plated contacts in environments where corrosion resistance is critical for long-term connection integrity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in handling various card thicknesses and its robust construction using thermoplastic materials. The 305 series is widely utilized in industrial and commercial applications demanding reliable electrical connections for edge-board interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching position counts and pitch, such as 305-048-500-201 or 305-048-521-202, provided the specific suffix parameters align with the application requirements.
