26PC SMT Series
The 26PC SMT (Surface Mount Technology) Series pressure sensor, the
first offering in the 20PC SMT family of pressure sensors, is a small, low
cost, high value, pressure sensing solution for use with printed circuit
boards (PCBs). Based on the long established reliability and accuracy of
the 26PC pressure sensor, the 26PC SMT offers reduced size with true
SMT capability. The smaller size reduces the sensor’s footprint on the
PCB, thereby reducing the size of the PCB. The 26PC SMT is the first
pressure sensor capable of being used with other SMT components on the
PCB, helping to lower installation costs and eliminate secondary
operations.
The sensor features Wheatstone bridge construction, silicon
piezoresistive technology, and ratiometric output for proven application
flexibility, design simplicity and ease of manufacture.
Although primarily designed for the medical industry, the 20PC SMT
pressure sensor may be applied in any industry that requires a surface
mount pressure sensor.
