New Multiturn Encoder-Technology POSIHALL®

Optical encoders are prone to fail under harsh environmental conditions, for example by the penetration of moisture into the sensor housing or by the destruction of breakable glass discs. ASM therefore developed the robust alternative to optical encoders: The magnetic multiturn encoder-technology POSIHALL® measures absolute angular position of a shaft over multiple revolutions by utilizing a gear coupled multi-hall sensor system. In contrast to current magnetic encoder technologies POSIHALL® is a true-absolute technology ensuring reliable and correct positioning after disturbances such as a power failure.
