The Siemens 7ME3960-0MD02 is a magnetic mounting frame designed to hold size C, D, E, universal, and high precision sensors in place on ferromagnetic surfaces. Group Code R3P3 and Product Group 4727 classify it within Siemens' ordering system for sensor accessories.
Listed as active and in a mature lifecycle stage, meaning it's a stable, established product without imminent end-of-life. Class C classification means it's manufactured or produced to order — not a stocked shelf item. It cannot be reused or returned against credit, so confirm the fit before committing the BOM line. Not RoHS-compliant per the listing, which may affect use in certain regulated markets or applications requiring RoHS exemption documentation.
The mounting frame is sized for multiple sensor form factors — size C, D, E, universal, and high precision — so it's a flexible bracket for a range of Siemens sensor heads rather than a one-size-only part. Because it's magnetic, it mounts directly to steel machine frames or panels without drilling holes — useful for temporary or repositionable sensor setups on conveyors, tank walls, or structural steel.
