Multiturn pots with slip clutch

16 February 2011 Passive Components

Bourns is offering a new ‘slip clutch’ option in specific multiturn potentiometer models.

Developed for models 3547, 3548 and 3549, the slip clutch is designed as a safety feature that helps prevent damage to the potentiometer in applications where the full travel is used, thereby increasing reliability and reducing potential service costs and system downtime.

The multiturn potentiometers with the slip clutch are well-suited to mechanised or machine-to-machine applications, such as linear actuators, cable transducers and mechanical position sensors where the mechanical actuator may occasionally rotate the shaft beyond the mechanical stops, or beyond the set number of turns. The slip clutch option is an internal design feature that does not alter the physical dimensions of the component. This new feature allows the device to idle at the extreme clockwise or counter-clockwise ends without inducing damage to the stops on the potentiometer.
