The Model ST-15 offers engineers an endless rotation version of the popular PT-15 rotary potentiometer. This new 360º version adds endless clockwise (CW or CCW) rotation as a part of the current features of the PT-15s already highly configurable mechanical and electrical specifications. That means a wide variety of off-the-shelf mounting methods, custom ohmic (resistance) values, tight linearity performance, along with the 7 different rotor designs and 15 standard shaft styles.
This potentiometer offers product designers the flexibility of allowing users full rotational access across the normal stops that have, up to now, limited mechanical rotation. With this design feature, engineers can now design product command features over a 340º range (active electrical travel). For maximum design versatility, the endless rotation feature can be combined upon request with detents to provide users tactile feedback on each setting and selection – with up to 51 unique detent positions. Virtually any appliance rotary feedback requirement can be configured using the PT-15s wide range of standard features. Other interesting optional features include flame-retardant plastics (meets UL Standard 94 V0), detents, rotors and shafts, long cycle life, SMT mounting and custom electrical angles.
