The Model STS-15 offers engineers an endless rotation SMD version of the popular PT-15 rotary control. This 360° 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 six different rotor designs.

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 340° 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 control requirement can be configured using the PT-15’s wide range of standard features. Other interesting optional features include stop positions (detents), a variety of rotors, long life 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

Piher’s High Speed Inductive Position Sensor are used by hybrid/electric vehicles powertrain systems to feedback the angular position, direction and speed of the rotor shaft to optimize control of the motor inverter.

The position sensor can be mounted on the same shaft as the electric machine rotor and sensing its position accurately is critical in order to drive the motor optimally by the vehicle’s control unit.

This solution provides high speed rotary motion sensing with a robust design against external magnetic interference fields generated from sources such as electric motors.

It uses the physical principles of induction in a wire loop and eddy currents to detect the position of a solid metallic structure that is sliding or rotating above a set of coils consisting of one transmitter coil and two receiver coils.
Custom product design packaging can be provided to meet any form, fit and function including the choice of wire harness and interface connector.

This innovative product family has been specifically developed to allow the integration of otherwise large and expensive external mechanisms into the body of the majority of the 6, 10 & 15 mm potentiometer series thus allowing a high range of configurations: special tapers, tolerances, linearity, cut track, etc.

This detent design not only adds a "click" sensation of position, but also offers enormous savings in both cost and space for any given application.

PT´s with detents also lend themselves perfectly to Industrial and Domestic Power Tool applications
where the detents prevent accidental movement of the potentiometer under vibration.

If high torque detents are required please see our Detent Control Mechanism (DCM) series datasheets.
Strong and weak detents (stop positions) can be mixed as per cutomer´s request.

The MTS-360 provides a true breakthrough in contactless sensor technology by combining a through-shaft design with 360º absolute position feedback in an ultra miniature size. The result is the smallest fully featured rotary sensor on the market with reliability up to 50 million cycles.

With its tiny size, engineers can now integrate a fully featured rotary sensor directly on their PCB without the packaging issues that typically accompany encoders or other absolute position devices. The exceptionally low profile fits easily in places that were previously too small for pre-packaged rotary sensors.

This ultra-miniature Rotary Position Sensor is ideal in optical imaging stabilization and precision biomedical devices, optical zoom devices, consumer electronics, instrumentation, HVAC systems, automotive control systems, marine controls, fork lift trucks, farm equipment, cranes, low speed motor feedback, valve position sensors and robotic and automation feedback system.
