345-050-500-178

Edgeboard Connectors Overview

The EDAC Inc. 345-050-500-178 is a standard card edge connector from the 345 series, designed for single-edge applications. It features 50 positions with a 0.100-inch (2.54 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin thickness and employs wire wrap termination. Constructed with a thermoplastic polyester housing, it supports through-hole mounting at a vertical angle and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Single-edge female connector configuration with 50 positions
• Gold-plated copper alloy contacts for reliable signal transmission
• Wire wrap termination method for secure circuit attachment
• Thermoplastic polyester housing providing thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• General-purpose electronic assemblies needing single-edge connectivity

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the specified 0.054 to 0.070 inch range to ensure proper contact engagement. Confirm that the assembly process accommodates wire wrap termination requirements rather than solder-based methods. Ensure the vertical mounting orientation aligns with the mechanical design constraints of the enclosure. Check for RoHS compliance status if environmental regulations apply to the final product deployment.

Edgeboard Connectors Selection Notes

Select this component when a single-edge interface is required for 50-position connections with a standard 2.54 mm pitch. The wire wrap termination makes it suitable for prototyping or environments where reworkability is prioritized over surface-mount convenience. Consider the vertical mounting profile and thermoplastic polyester material properties for thermal management needs. Evaluate the 3 A current rating against the specific electrical load requirements of the application circuits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, which specializes in standard card edge connectors. The series offers various configurations including single and double edge options with different pin counts. The 345-050-500-178 specifically addresses single-edge applications, distinguishing it from dual-edge counterparts like the 345-050-541-504. The series is characterized by its use of gold-plated contacts and thermoplastic polyester housings for durability.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 345-050-500-201 and 345-050-540-201, which share identical positioning and pitch specifications. These alternatives may differ in minor packaging or supplier-specific identifiers but maintain functional equivalence. Verify that any replacement maintains the wire wrap termination style and single-edge configuration to ensure mechanical compatibility.
