The world's smallest and lightest altitude encoder.
There are two versions of this model:
Standard Version SSD120-30N
Version SSD120-30N-MOD1 for NARCO AT-5A, 6A, 50, 50A Transponders. The Narco AT-5A, AT-6A, AT-50* or AT-50A transponder will not accept data from the SSD120-(XX)N() Altitude Digitizer. A recent modification to remove the output decoupling capacitors is required and this version includes that modification.
