Piher’s new PT15 offers engineers an endless rotation version of the popular PT15 rotary control. This new 360º version adds endless clockwise (CW or CCW) rotation as a part of the current features of the PT15s already highly configurable mechanical and electrical specifications. That means a wide variety of off-theshelf mounting methods, custom ohmic (resistance) values, tight linearity performance, along with the 7 different rotor designs and 15 standard shaft styles.

This sensor, already popular in hundreds of white goods and appliance panel control and sensing
applications, now 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 new 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 with detents to provide users tactile feedback on each setting and selection – with up to 51 unique and highly repeatable detent positions. Virtually any appliance rotary control requirement can be configured using the PT-15s wide range of standard features. Other important features include flame-retardant plastics (meets UL Standard 94 V0), detents, rotors and shafts, long cycle life, SMT mounting and custom electrical angles.

Engineered to serve as a highly cost-effective control potentiometer for most consumer applications such as ovens, ranges, dishwashers, power hand tools, washing machines and HVAC systems, it also can fit many automotive convenience electronic applications.
