More Robust Design

Navitar’s motorization design, available on the 12X and Zoom 6000 sys-
tems, 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. 

Our motorized zoom lenses include LabView “VI” and Windows user inter-
face. They can be controlled via serial RS-232 or USB.  The control system 
is available as either table top or board level.

Users can choose to motorize the zoom and focus axis, or just the zoom.  
We have three different motor types available:

• 2 Phase Stepping Motor (Faulhaber)
• 5 Phase Stepping Motor (Oriental, Vexta)
• DC Servo with Encoder (Faulhaber)

Zoom 6000 and 12X Zoom Hall-Effect system diagrams can
