SM6250 Ultra Low Pressure Sensor has ASIC
Pressure Medium: Air/Gas
Sensor Type: Differential
Supply Voltage: Under 5V
Output Signal: Millivolt
Pressure Range: 4” H2O to 3 psi
Kind: Board Level

The SM6250 Series combines state-of-the-art sensor technology with CMOS mixed-signal processing technoogy in a low profile SOIC-16 package with dual holes. Pressure is measured from the backside, while additional protection to the electronic circuitry is provided by protective gel on the topside. 

The SM6250 is shipped uncalibrated and uncompensated with only a functional test. However, an internal ASIC lets customers calibrate the sensor should they wish to. Pressure range of ±0.7 psi.


  • Uncalibrated sensor
  • ±0.7 psi (±50 mbar)
  • Differential pressure configuration (available now is model SM6250-DDN-T-050-000)
  • Amplified analog output can be created by the user
  • Insensitive to mounting orientation

Typical Uses

  • Medical - negative pressure wound therapy, health monitoring, ventilators, CPAP
  • Gas flow instrumentation
  • Pneumatic gages
  • Safety cabinets
  • Sports equipment
