Navitar s motorization design, available on the 12X systems, integrates magnetic Hall-Effect sensors to reference position location. Hall-Effect sensors are solid state devices with no moving parts. They are based on the Hall-Effect, named after its discoverer Edwin Hall in 1879. The Hall-Effect sensing mechanism utilizes a magnetic field to trigger a pulse in a semiconductor circuit. Compared to photo-electric sensors, the Hall-Effect sensors are not affected by harsh, dirty or dusty environments, ambient room light, or variation in system voltages.
