The Vishay 21A11B10 is the Model 21 dial in silver and black. The Model 21 is a 15-turn, 46mm diameter dial. It is the perfect choice of dial for industrial appliances which require a view of the number of turns.
The Model 21 features a round Vernier scale which offers accurate measurement readings. The outside of the dial has a high-quality satin chrome finish with black text and markings for easy readability. The viewing window has a black background with white text for clear visibility of the number of turns.
The readout of the Model 21 dial will increase by turning clockwise and decrease by turning anti-clockwise. With the help of a locking brake, you can keep your reading set. The Model 21 is able to display readings of up to 1499 turns. The number within the smaller window (0-14) shows the complete number of turns or the drive sleeve.
Mounting the Model 21 is really straight-forward, and instructions on this are included. It is mounted directly onto the transducer shaft.
