Transducer description
The Simrad MS70 transducer is a short cylindrical container with 800 transducer elements. The transducer elements are located at the "bottom" of the transducer. The transducer cables are provided as 25 individual cables in three bundles. Each cable is terminated in a large male connector.

The Simrad MS70 transducer face is plane, and consists of a ceramic-polymer composite matrix. The matching transformer for each transducer element is located inside the transducer. This allows for a low impedance connection to the Transceiver Unit. The transducer is connected to the rear side of the three TRXU subracks in the Transceiver Unit using 25 cables.
The maximum length of the transducer cables is 30 meters, while the minimum length is 15 meters. The transducer cables can not be spliced.
Note
The required length of the cables to fit each specific installation must be determined before the transducer is ordered.
If the transducer is installed in a drop keel, the transducer cables must be protected. Each cable must be fitted with a protective hose. The protective hose starts inside the transducer. Protection must be used along the entire length of the cables, and all the way up to where the cables penetrate the hull.
Note
The transducer - with the cabling - is a delicate item. Great care must be shown during all handling. Even minor damages to the transducer cable may cause water to penetrate both the cable and the transducer body. A physical blow to the transducer face may easily damage one or more elements.
