345-072-500-202

Edgeboard Connectors Overview

The EDAC Inc. 345-072-500-202 is a standard card edge connector from the 345/395 series, designed for dual-edge card applications. It features 72 positions with a contact spacing of 0.100 inches (2.54mm) and a row spacing of 0.200 inches (5.08mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with gold-plated contacts on a copper alloy base, it ensures reliable electrical performance. The housing is made of green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates two-sided card edge connections for increased pin density.
• Gold-plated copper alloy contacts provide corrosion resistance and stable signal transmission.
• Thermoplastic polyester housing offers mechanical stability and high insulation resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instruments needing reliable signal integrity

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required configuration, as suffixes may denote variations in flanges or mounting styles without altering core electrical function. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with the target PCB thickness of 0.062 inches to guarantee proper mechanical engagement and contact retention during operation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface is required with a 72-position count. The 0.100-inch pitch is suitable for general-purpose digital and analog signals. Consider the vertical mounting style and through-hole termination method for panel or chassis integration. Evaluate the current rating and temperature range against system requirements to ensure long-term reliability under operational stress.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345/395 series, which provides a comprehensive range of card edge connectors for various industrial and commercial applications. The series is known for its standardized dimensions and reliable performance in harsh environments. The 345-072-500-202 variant specifically addresses needs for higher density connections using dual-edge technology, offering a compact solution for space-constrained designs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 345 series parts for similar position counts. Verify mechanical fit and electrical specifications before substituting with generic equivalents. Ensure any alternative maintains the same 0.100-inch pitch and dual-edge compatibility to preserve system integrity.
