The 7ME3960-0SM60 is a mounting strap from the SITRANS FS220 ultrasonic flowmeter family, sized for dedicated transducers on pipe diameters DN2100 through DN3000. It carries the legacy number 1012MS-6.
Classified as a made-to-order product (Product class C), so it's manufactured per order and cannot be returned or reused. That's another SKU you want to be certain of before committing the BOM line. Not RoHS-compliant — relevant if your site or end customer has RoHS exemption restrictions for the flowmeter assembly. Group code R3P3 and product group 4727 are the internal Siemens cataloging codes for this strap; useful for cross-referencing in Siemens logistics or spare-parts portals.
