Frequently Asked Questions
What is the contact pitch and total position count of the M20-9761746?
The Harwin M20-9761746 is a 34-position dual-in-line (DIL) connector with 17 positions per row at a standard 2.54 mm pitch. The body measures approximately 1.7 inches in length, making it pin-compatible with standard 34-pin DIL sockets used in through-hole PCB assemblies.
What contact plating does the M20-9761746 use and how does that affect solderability?
The M20-9761746 features tin (Sn) plating over a nickel (Ni) barrier on its 5.8 mm through-hole pins. Tin plating ensures excellent solderability using standard no-clean or water-soluble flux, making it compatible with wave soldering and hand-soldering processes in high-volume industrial production.
Is the Harwin M20-9761746 suitable for use in RoHS-restricted industrial equipment?
Yes. The M20-9761746 carries full RoHS compliance as indicated by its Pbfree Code designation. The connector body is 0.1 inch deep and 0.2 inch wide, and its tin-plated contacts avoid lead-containing finishes, meeting EU RoHS and similar international environmental regulations for industrial and commercial electronics.
How does the M20-9761746 compare to similar Harwin M20 series connectors for backplane or daughter-card applications?
Within the Harwin M20 series, the M20-9761746 is a straight-pin THT plug with 34 positions at 2.54 mm pitch, suited for direct PCB mounting. For right-angle or higher pin-count variants, other M20-97 models offer up to 50 positions and right-angle orientations, while retaining the same 2.54 mm pitch and nickel-barrier tin-plated contact finish.
