Headers, Male Pins datasheet and documents for M20-9703345

M20-9703345

Headers, Male Pins Overview

The M20-9703345 is a vertical pin header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features a 2.54 mm (0.100 inch) pitch and consists of 33 positions arranged in a single row. The connector utilizes brass contacts with gold plating for reliable signal transmission. It is intended for through-hole mounting on printed circuit boards. The housing is constructed from black nylon material, providing structural integrity and electrical insulation. This component supports standard soldering processes for secure attachment to the PCB.

Headers, Male Pins Feature Summary

Industrial control systems

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and insulation material grade against the official datasheet before integration. Confirm that the through-hole pad layout matches the manufacturer's recommended footprint dimensions. Ensure compatibility with standard reflow or wave soldering profiles specified for gold-plated terminals. Check for any RoHS compliance documentation required by your supply chain regulations.

Headers, Male Pins Selection Notes

Select this part when a single-row, vertical header with gold contacts is required for a 33-position interface. Consider the M20 series if high-density connectivity with a 2.54 mm pitch is needed. Evaluate the thermal and current ratings against the application load. Compare against tin-plated alternatives if cost reduction is prioritized over long-term oxidation resistance.
