346-034-541-604

Edgeboard Connectors Overview

The EDAC Inc. 346-034-541-604 is a standard card edge connector receptacle featuring 34 positions with a 3.18 mm (0.125 inch) contact spacing. Designed for single-edge board mating, it utilizes a copper alloy contact material finished with gold plating to ensure reliable signal transmission. The component supports a current rating of 3 A and accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm. It employs a through-hole mounting style with vertical orientation and wire wrap termination type. The insulator body is constructed from green thermoplastic polyester, providing structural stability in electronic assemblies.

Edgeboard Connectors Feature Summary

• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical conductivity for signal integrity.
• Thermoplastic polyester insulator offers durable housing suitable for standard industrial operating temperatures.
• Vertical through-hole design facilitates secure mechanical attachment to printed circuit boards.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific pin count and termination style against the target PCB footprint before ordering. Confirm that the supplier provides original manufacturer documentation to ensure compliance with RoHS standards. Check for availability constraints as distribution status may vary by region. Ensure the receiving facility has appropriate handling procedures for sensitive electronic components to prevent electrostatic discharge damage during storage and installation.

Edgeboard Connectors Selection Notes

Select this connector when a 34-position interface with 0.125-inch spacing is required for single-edge card applications. The gold plating is essential for environments requiring high reliability and low contact resistance. Consider the vertical mounting profile and wire wrap termination method when designing the assembly process. Evaluate the thermal performance of the polyester insulator against the operational temperature range of the host system to ensure long-term durability.

Edgeboard Connectors Part Context

This component belongs to the EDAC 346 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulators and copper alloy contacts. Variants within the series differ primarily in position count and specific termination configurations. The 346 series is widely utilized in general-purpose electronic systems requiring robust board-to-board or board-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 346-030-541-201 or 346-044-500-103 if different position counts are acceptable. Verify that any substitute maintains the same 3.18 mm pitch and vertical through-hole mounting characteristics. Ensure the replacement part matches the gold plating specification and current rating requirements of the original design.
