Slide Potentiometers are used to provide a voltage or current that is proportional to the position of a slide located along a resistive strip, which makes them useful for linear position sensing. The PTA3043-2015DPA103 is a slide potentiometer from NVE Corporation, and it is designed to meet low-profile requirements in applications where a larger device size is impractical. This article will focus on the application field and the working principle of the PTA3043-2015DPA103.

The PTA3043-2015DPA103 is designed for applications in the aerospace, automotive, and industrial markets. It is a linear low-profile slide potentiometer that can serve as a miniature linear position transducer or a variable resistor. The device measures a total travel of 5.0 mm over the resistive strip and offers a travel direction of either clockwise or counter-clockwise. In addition, the device has an output impedance of 10kOhms and a linearity of ±15%.

The PTA3043-2015DPA103 features a parallel-arm design that provides superior linearity. It consists of 7 resistive elements that are indexed to the slide by multipole connectors. When the slide is moved along the resistive strip, the multipole connectors engage the resistive elements and generate a signal that is proportional to the position of the slide along the resistance strip. The output signal from the slide potentiometer is amplified by an op-amp before being provided to the application circuit.

The PTA3043-2015DPA103 is designed to withstand long intervals of rugged use and is tested to the requirements of MIL-STD-202F and MIL-PRF-83401C. It has an operating temperature range of -55°C to +125°C and is delivered with a self-calibrating dynamic temperature compensation feature. The device offers a rated life of 10 million operations, and it is sealed with a hermetic cover for moisture protection.

In summary, the PTA3043-2015DPA103 slide potentiometer from NVE Corporation is designed for applications in the aerospace, automotive, and industrial markets. It features a parallel-arm design and 7 resistive elements that are indexed to the slide. As the slide is moved along the resistive strip, the output signal is proportional to the position of the slide. The signal is amplified by an op-amp before being provided to the application circuit. In addition, the device has an operating temperature range of -55°C to +125°C and is tested to the requirements of MIL-STD-202F and MIL-PRF-83401C.
