Frequently Asked Questions
What contact pitch and body length does the Harwin M20-9991245 use?
The M20-9991245 features a 0.1-inch (2.54 mm) contact pitch, which is the industry-standard spacing for through-hole and wire-to-board connectors. The body length is 1.2 inches, accommodating a 12-position single-row or corresponding dual-row configuration suitable for moderate signal-count interconnects.
What contact finish does the M20-9991245 use and why does it matter?
The M20-9991245 uses gold (Au) contact finish on the termination contacts. Gold plating provides superior corrosion resistance and low, stable contact resistance over thousands of mating cycles, making it ideal for high-reliability industrial and test equipment applications where intermittent contacts would cause system faults.
Is the Harwin M20-9991245 compliant with RoHS and other environmental regulations?
Yes, the M20-9991245 is fully RoHS compliant and Pb-free, meeting EU Directive 2011/65/EU restrictions on hazardous substances. This compliance is documented in the product specifications, facilitating CE marking and export to Europe, Japan, and other markets with strict environmental regulations for electronic assemblies.
What types of systems is the M20-9991245 best suited for?
The M20-9991245 is best suited for industrial control systems, prototype development boards, and modular test equipment using standard 0.1-inch pitch wire-to-board connections. The receptacle body style allows easy cable assembly mating, and the gold-plated contacts support reliable signal integrity in environments with up to 1 A per contact current carrying capacity.
