NSN 5990-00-677-6480
Part Details | DIFFERENTIAL TRANSMITTER SYNCHRO
5990-00-677-6480 A synchro, the rotor of which is mechanically positioned for modifying electrical angular information, received from a transmitter synchro and transmitting to receiver synchro or control transformer synchro electrical information corresponding to the sum or difference of the electrical input angle and its rotor position angle. Does not include variable resistors, goniometers, variable transformers, or items with dials.
