Frequently Asked Questions
What pitch and pin count does the Harwin M22-2512046 connector offer?
The M22-2512046 is a 20-position single-in-line connector with a 2.3 mm pitch between contacts and a 3.5 mm pin length for through-hole soldering. This combination supports dense single-row wiring in compact PCB layouts while providing sufficient pin length for reliable solder joint formation in automated wave soldering processes.
What contact finish is used on the M22-2512046, and how does it affect performance?
The M22-2512046 uses tin (Sn) over a nickel (Ni) barrier contact finish on the termination side. The nickel barrier prevents tin diffusion into the base metal, maintaining low contact resistance over time and extending connector service life. This finish is compatible with standard lead-free soldering at typical reflow temperatures of 250°C to 260°C.
Is the Harwin M22-2512046 suitable for use in products sold in European markets under RoHS regulations?
Yes, the M22-2512046 is fully RoHS compliant, meaning it is free from restricted hazardous substances including lead, mercury, and cadmium. This compliance enables the connector to be used in electronic assemblies sold in the European Union and other markets adopting RoHS directives, without requiring exemptions or additional documentation for the connector itself.
What PCB assembly methods are compatible with the M22-2512046 through-hole connector?
The M22-2512046 uses through-hole termination with a 3.5 mm pin length, making it compatible with wave soldering and selective soldering processes. The straight SIL configuration allows automated insertion into PCB through-holes at a 2.3 mm pitch grid, and the pin geometry is compatible with standard PCB drill diameters used in industrial board manufacturing.
