SM5420 Absolute Pressure Sensor With Millivolt Output

The SM5420 is a small outline SO-8 packaged pressure sensor. The sensor is intended for high volume applications where cost is a critical factor, such as consumer tire pressure gauges or automotive tire pressure monitoring. The SM5420 is configured as an absolute sensor in full-scale ranges of 15 psi, 30 psi and 100 psi. It is designed to be surface-mount on ceramic or PC board substrates by high volume OEM manufacturers.

The SM5420 is available in a ported configuration to allow positive positioning of a pressure source over the inlet or in a non-ported configuration to be used for sensing general environmental pressures or with an O-ring seal.

The part comes with gel over the die as standard; the part can be ordered without gel in high volumes where the maximum stability is required, such as barometric, weather station sensing applications. The SM5420 is shipped tape-and-reel.

Low cost - approximately $1 in quantities of 25,000. Use with sensor signal conditioners ZSC31010 or ZSC31014 for analog or digital output (see links at bottom of this page). DOWNLOAD OUR BAROMETRIC
