Sensores / potenciómetros SMD ofrecen multitud de configuraciones

Los equipos automáticos de montajes electrónicos SMD pueden colocar componentes con mucha más rapidez y precisión que las tecnologías anteriores. En lugar de terminales que atraviesan un PCB, los componentes SMD tienen una superficie plana que es soldada directamente al PCB en unas zonas llamadas PADS que contienen una pasta soldable (flux). Durante el proceso de soldadura se posiciona cuidadosamente el componente encima de los pads y se somente a una alta temperatura, normalmente en un horno de infrarojos, hasta que se derrite la pasta y el componente queda soldado. Este proceso requiere normalmente unas altas temperaturas por lo que el componente debe ser cuidadosamente diseñado para soportarlas sin problemas. ¡¡Aquí es donde los componentes de Piher marcan la diferencia con el resto de competidores!!

potenciometro SMD

El rendimiento de los componentes SMD de Piher es perfecto gracias a la cuidadosa selección de materiales para soportar con creces las temperaturas usadas en procesos de soldadura SMD sin plomo (reflow). Por fin podrá decir adiós a los problemas de temperaturas en la soldadura sin plomo. Pídanos muestras y compruébelo.

Los componentes SMD se utilizan en un número creciente de aplicaciones y diseños, esto es conocido por Piher y por ello ofrece una amplia gama de productos compatibles SMD compatibles con soldadura libre de plomo. Algunos ejemplos son los productos N6S, N/S/E-15S,  PS-10 (sensor SMD de 10mm) y PS-15 (sensor SMD de 15mm). Estos productos pueden ser personalizados según las necesidades particulares de cada cliente.

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.

The PS10 & PS15 series are available with different rotor designs and up to 15 shaft styles. This offering allows PIHER to configure a custom sensing solution for virtually any control or position feedback requirement.  The result is a customized sensor that maximizes board density, reduces weight and eases assembly while achieving the engineer’s critical sensor design goals for the application.

A wide range of options, including up to 13 detents, allows further customization.  Detents not only add a crisp «click» sensation for each position without affecting the original sensor specification or performance, but also offer significant savings in both cost and space; and are particularly advantageous in industrial and domestic power tool applications to prevent accidental movement.  All Sensors are available with or without detents.

«The PS10 & PS15 allow engineers more design freedom because of the significant configurability provided with our wide array of shafts, rotors and detents,” says Dave Meehan, Applications Engineer with PIHER.  “It is often difficult for engineers to locate all the features they want in a 10mm package size, but we can meet their exact requirements to this small size by tooling either a rotor, shaft and detent configuration.”

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 (PS15), custom tapers, measured linearity, and different electrical angles.  The devices are both RoHS and REACH compliant.
