The variety of physical configurations available and the ability to withstand today's manufacturing environment offers the designer flexibility in selecting the best trimmer for the application.
Bourns single-turn trimmers are actuated by a direct-drive mechanism. It consists of a simple rotor with a slot, whose wiper movement is traversed in a circular path. Package types available include:
Sealed trimmers are built with an o-ring seal to prevent entrance of moisture and serve as a mechanical restraint to prevent unwanted wiper movement.
Open-frame trimmers are not sealed to withstand a cleaning process and are usually lower in cost.
Single-turn trimmers are designed with a direct-drive actuation for resistance adjustment and suitable for applications such as data input for digital equipment, where the level of accuracy is not critical.
