MEMS Sensor WPAS02

  • MEMS-Sensor-WPAS02.png


The WPAS02 series is a plastic-encapsulated pressure sensor packaged with high-precision MEMS pressure-sensitive chips and mature production processes. The standard pin structure is convenient for customers to use, and at the same time, it provides OEM customers with low-cost plastic-encapsulated pressure sensor solutions. WPAS02 series plastic packaged pressure sensors are only suitable for dry and non-corrosive gases. Different ranges and output methods can be customized according to customer requirements.


* Package form: SOP6
* Wide operating temperature range: -20℃~80℃
* Not temperature compensated
* Suitable for module assembly
* High precision at room temperature: ±0.3%FS
* Low cost and small size
* High reliability
