What are the key features of M50-3101045?
- 10-position single-row socket connector on 1.27 mm pitch enabling high-density board-to-board connections in minimal PCB footprint
- Gold-plated (Au) termination contacts for superior corrosion resistance and long-term signal integrity across repeated mating cycles
- RoHS compliant construction with 0.45 inch body length for integration into environmentally conscious product designs
What is M50-3101045 used for?
The M50-3101045 is suited for compact board-to-board and wire-to-board signal connections in portable electronics, medical devices, and industrial instrumentation where 1.27 mm pitch density and reliability are critical. Its 10-position single-row socket layout accommodates up to 10 signal lines in a body measuring 0.45 inch length and 0.181 inch depth, ideal for space-constrained PCB designs. The gold-plated contacts ensure consistent low-resistance mating performance over many connection cycles in test and measurement or field-replaceable module applications.

Frequently Asked Questions
What pitch and number of positions does the Harwin M50-3101045 socket connector offer?
The M50-3101045 is a 10-position single-row socket connector on a 1.27 mm pitch, providing a compact high-density interconnect solution. Its body measures 0.45 inch in length and 0.181 inch in depth, making it well suited for tight board layouts common in portable and embedded electronics.
How does the gold-plated termination of M50-3101045 benefit long-term reliability in repeated mating applications?
The gold (Au) plated termination contacts on M50-3101045 deliver extremely low contact resistance and outstanding corrosion resistance, maintaining stable signal integrity across hundreds of mating cycles. This is especially valuable in test-and-measurement fixtures or modular field-service assemblies where connectors are disconnected and reconnected frequently under 3.3 V or 5 V logic signal levels.
Is M50-3101045 suitable for use in medical or industrial devices requiring environmental compliance?
Yes, M50-3101045 carries a RoHS compliant designation (Pb-free), satisfying the requirements of IEC 62321 and EU RoHS Directive 2011/65/EU. This makes the connector an acceptable choice for medical device PCBs, industrial control modules, and consumer electronics where lead-free assembly and regulatory compliance are mandated.
How does M50-3101045 compare to a 2.54 mm pitch connector in terms of board space savings?
The M50-3101045 uses a 1.27 mm pitch versus the standard 2.54 mm pitch, effectively halving the connector's footprint length for the same 10 contact count. For a 10-position row, this reduces the occupied PCB length from approximately 22.86 mm (2.54 mm pitch) to around 11.43 mm, yielding roughly 50% board space savings in dense designs.
