Product Details | TRANSMITTER SYNCHRO

5990-00-421-0956 A synchro consisting of a stator and rotor inductively coupled. The electrical output of the stator into a receiver synchro, a control transformer or differential synchro is dependent upon the position of its rotor. Does not include variable resistors, goniometers, variable transformers, or items with dials.
