## **Description** 

PS781-12G0L1 is a highly stable piezo-resistive pressure sensor with wide temperature compensation and zero correction. It contains a highly stable silicon die, stainless steel 316L housing with diameter 19mm. The measured pressure is transmitted onto the silicon die through the 316L diaphragm and inner media. This transforms the measured pressure into an electrical signal. 

## **Product Configuration** 

Application: Highly Stable Pressure Sensor Pressure Type: Gauge Electrical Connector: 0.5mm Kovar Pin

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
