305-036-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-036-521-502 is a standard card edge connector header featuring 36 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row pitch of 3.56 mm. Designed for panel mounting at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector employs a solder lug termination method. The insulator body is made of thermoplastic material, providing structural integrity within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided PCBs
• Gold-plated copper alloy contacts ensure corrosion resistance
• Vertical panel mount style provides secure mechanical fixation

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm termination type and insulation color. Ensure the target PCB thickness aligns with the 1.57 mm specification. Confirm that the panel mounting orientation matches the vertical installation requirement. Cross-reference the 36-position count with the system schematic to prevent pinout mismatches during integration.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for thick PCBs. The 3.96 mm pitch offers wider spacing compared to standard 2.54 mm connectors, reducing crosstalk risks. The vertical panel mount style simplifies assembly in enclosed chassis environments. Verify compatibility with the mating card edge profile before finalizing the bill of materials.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its heavy-duty construction and suitability for demanding industrial applications. The 305 series typically features thermoplastic insulators and gold-plated contacts, ensuring durability in harsh environments where vibration and temperature fluctuations are present.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical position counts and pitch specifications. Verify that any alternative maintains the same 3.96 mm spacing and 1.57 mm board thickness tolerance. Check for equivalent current ratings and termination styles to ensure functional interchangeability without redesigning the panel cutout.
