Frequently Asked Questions
What are the body dimensions and pitch specifications of the Harwin M50-3100645 connector?
The Harwin M50-3100645 has a body length of 0.25", breadth of 0.122", and depth of 0.181", with a contact pitch of 0.050" (1.27 mm). Gold-plated termination contacts and a socket body/shell style enable reliable board-to-board mating in compact PCB assemblies with minimal footprint impact.
In which miniaturized electronics applications does the M50-3100645 provide an advantage over larger pitch connectors?
The M50-3100645's 1.27 mm pitch is approximately half that of standard 2.54 mm connectors, enabling twice the connection density in the same PCB area. This makes it suitable for portable medical diagnostic devices, compact drone avionics boards, and IoT gateway modules where PCB space savings of 40-60% are achievable compared to 2.00 mm or 2.54 mm pitch alternatives while maintaining reliable gold-contact signal integrity.
Is the Harwin M50-3100645 compatible with RoHS manufacturing processes and what does its YTEOL rating indicate?
Yes, the M50-3100645 is RoHS compliant for lead-free soldering with gold-plated termination contacts compatible with standard reflow processes at up to 260°C peak temperature. Its YTEOL (Years to End of Life) rating of 9.4 years indicates Harwin's commitment to long-term product support, making it a reliable choice for industrial and medical equipment with extended production lifespans requiring component availability for 9+ years.
What mating connectors from Harwin's M50 series are compatible with the M50-3100645 socket?
The M50-3100645 socket is part of Harwin's M50 series designed to mate with M50 series header connectors sharing the same 0.050" (1.27 mm) pitch. Compatible mating headers include straight and right-angle versions available in single-row and dual-row configurations with pin counts from 2 to 100 positions. Stack heights of 8 mm, 11 mm, and 15 mm mating combinations are available for flexible board separation in embedded computing and measurement modules.
