Surface mount rotary position sensors featuring flexible configuration capabilities in miniature package

Responding to the widespread use of surface mount technology for electronics manufacturing, PIHER is introducing SMD versions of its popular PT10 and PT15 Potentiometer. The new devices, the PS10 and the PS15 Rotary Position Sensors, feature configurable capabilities for complete design flexibility in a small package. The sensors offer a new surface mountable solution for detecting changes in angle and position and converting them into a highly reliable voltage output. The sensors can be processed by standard automated placement equipment and reflow (or lead-free reflow) soldered. For applications where rotor angle is critical, locating pins are available.

Specifically designed for leadfree relfow soldering processes, other features of this product are:

· Dust proof enclosure.
· Embossed tape.
· Carbon resistive element.
· Also upon request:
Special resistive values, tighter tolerances, tapers...       
Long life model for low cost control pot. applications
Wiper positioned at initial, 50% or fully clockwise.
Self extinguishable plastic UL 94V-0 and moisture sensitivity level 1 (PS-15 only).
Mechanical detents.

Standard specifications
·    Tolerance: 30%
·    Values: 10k
·    Taper: Linear
·    Rotation angle: 265º±5º
·    Mechanical life: 10k cycles
·    Operating temperature: -40ºC to +85ºC
·    Rotation Torque: 0.5 to 2.5 Ncm.
·    Nominal Power: 0.15 W @ 50°C (122°F)

In developing the PS10 and the PS15, PIHER’s engineers paid particular attention to the surface mount land patterns (footprints or pads) that define the locations where components are soldered to the PC board.  The PS15’s land patterns have been optimized to maximize solder joint strength, clean ability, testability, and repair all critical features in the overall produceablity of the board assembly.

These SMD Rotary Position Sensors offer application for both feedback and control where frequent adjustment or feedback is required.  The shaftless design allows for employment of different engagement mechanisms, such as a customized shaft, a motor control, a human interface adjustment, or a mechanical arm position locator. The sensors can also control variable outputs including frequency, change in motor speed or volume.  Typical applications include test and measurement equipment, consumer electronics, appliances, small engines, robotics, motion controllers, and medical equipment control panels.  

In addition to the wide selection of rotors and detents, 14 different shafts and thumbwheels are available in nine colors in either standard or UL94 compatible plastic.  Available options include SPDT switch, 100k life cycle (PS-15), custom tapers, measured linearity, and different electrical angles.  The devices are both RoHS and REACH compliant.


PIHER offers complete design-in engineering services that can supply variations of the PS-15 & PS-10 and PS-6 to meet customer specifications.
