Mounting Methods
Typically, precision potentiometers are mounted onto the end product in either of two methods depending on the application.
Servo mount is used in applications where the potentiometer shaft is coupled to a motor or other mechanical driven applications. Figure 11.5 illustrates a servo mount type potentiometer.

Bushing mount is used in applications where the potentiometer shaft is mounted through a front panel and is to be adjusted manually. Figure 11.6 illustrates a bushing mount type potentiometer.

Printed circuit mount is a third and less commonly used mounting method. With this mounting method, the potentiometer is directly mounted on the PCB and soldered in place by the solder terminals. Model 3590P offers this type of mounting.
