The pressure sensors/switches in the AMS 5105 series combine a high-precision OEM pressure sensor with a programmable pressure switch in one package. AMS 5105 has one analog voltage output and two independent logic switching outputs. The analog voltage output is ratiometric to the supply voltage of 5 V. The switching outputs are software configurable as normally open, normally closed or in window mode; thresholds and hysteresis can be set individually. The pressure sensors/switches are calibrated and compensated for across a temperature range of -25 to +85°C.

AMS 5105 comes in a dual in-line package (DIP) for assembly on printed circuit boards (PCBs). The electrical connection is made via the DIP solder pins; pressure is connected via two vertical metal tubes. AMS 5105 is available for various applications and pressure ranges: differential (relative) devices in ranges from 0…5 mbar up to 0…7 bar, two absolute pressure variants for 0…1 bar and 0…2 bar and a barometric variant. Bidirectional differential devices are available in different ranges from -5…+5 mbar up to -1…+1 bar. Other pressure
ranges or customized modifications are available on request.
