Trans-Cal Industries SSD120

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.

Features

• The best warranty in the business: 42-month manufacturer direct replacement. If your Trans-Cal encoder experiences a warranty-covered failure, it'll be replaced with a brand new unit with a new 42-month warranty.
• Average MTBF: 9.7+ years. That’s right, Trans-Cal encoders are among the most reliable on the market, commonly providing reliable service for over 10 years.
• Pin for pin replacement for most other manufacturers' encoders.
