Overview POSIHALL®

The absolute POSIHALL® magnetic multiturn-angle sensors measure angular positions over multiple revolutions using a noncontact magnetic measuring principle, which allows wear free operation. POSIHALL® angle sensors operate reliably and precisely even with high levels of vibrations and shocks and under extreme temperatures of -40°C to +85°C. The rugged stainless steel housing with completely enclosed electronics provides extra protection against extreme environmental conditions, which makes them the ideal solution for Heavy Duty applications in the field of mobile working machines. Due to their robust design POSIHALL® sensors are far superior to optical angle encoders in this specific area.

The functional principle

POSIHALL® sensors detect the absolute angular position of a shaft over multiple revolutions by utilizing a gear coupled, ASM-patented Multihall sensor array that applies a magnetic Nonius principle. POSIHALL® sensors are mounted directly onto the machine’s rotation axis or onto ASM POSIWIRE® / POSITAPE® sensors for measuring the rotations of the cable drum.
