Hall Effect Sensors
Introducing Navitar’s new line of standard equipment
featuring motorized zoom lenses with advanced computer control. These
new motorized zoom lenses are designed to offer systems integrators and
end users a complete optical solution. Navitar’s new motorization
design integrates magnetic Hall Effect sensors to reference position location.
The Hall Effect sensing mechanism utilizes a magnetic field to trigger
a pulse in a semiconductor circuit. This principle is now used in almost
all ignition systems currently being produced. Compared to older photo-electric
sensors, the Hall Effect sensors are insensitive to contamination, room
light and variation in system voltages. User can choose to motorize the
zoom axis, focus axis, or both. Three different motor types are available:
2 Phase Stepping Motor (Faulhaber)
Available August 1, 2003
Two phase current mode steppers.
5 Phase Stepping Motor (Oriental, Vexta)
September 2003 Delivery
Small footprint motor with high torque.
DC Servo with Encoder (Faulhaber)
November 2003 Delivery
Brush type coreless DC micro motors with integrated magnetic encoders.
Specific motor information is available on request.
