346-048-540-602

Edgeboard Connectors Overview

The EDAC Inc. 346-048-540-602 is a standard card edge connector receptacle featuring 48 positions in a single row configuration. It utilizes a 3.175 mm (0.125 inch) pitch and is designed for PCBs with a thickness of 1.57 mm. The component employs through-hole mounting with vertical orientation and PC pin termination. Contacts are gold-plated copper alloy, rated for 3 A current. The housing is constructed from thermoplastic polyester, offering an insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Single-row receptacle design with gold-plated contacts for reliable signal transmission
• Thermoplastic polyester housing providing high insulation resistance and thermal stability
• Vertical through-hole mounting style compatible with standard panel or board installations

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard module form factors
• Automotive electronics applications demanding stable connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm plating thickness, housing color, and terminal type variations. Ensure compatibility with the target PCB stack-up and hole dimensions before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the vertical mounting orientation aligns with the mechanical assembly constraints of the final product design.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface with a 3.175 mm pitch is required for vertical board-to-board or backplane connections. Consider the 1.57 mm board thickness specification to ensure proper contact engagement. Evaluate the 3 A current rating against the application's power distribution needs. Verify that the through-hole termination method suits the manufacturing process and mechanical stress requirements of the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors. The series offers various position counts and mounting styles while maintaining consistent pitch and electrical characteristics. The 346 series is widely used in modular electronic systems where reliable, repeatable connection cycles are necessary. This specific model represents a mid-range position count option within the single-row vertical receptacle category.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 48-position count, 3.175 mm pitch, and vertical through-hole mounting style. Verify that alternative components support the same 1.57 mm board thickness and provide equivalent gold plating specifications. Check for identical housing material properties to ensure similar thermal and electrical performance ratings.
