TE Connectivity Measurement Specialties Pressure Sensors

TE Connectivity’s MS5840-02BA pressure sensors are optimized for use in space-constrained altimeter applications such as wearables, drones, bike computers, and more. The MS5840-02BA is just 1.7 mm tall and has a 3.3 mm square footprint, allowing it to be used in small and thin devices.

It also has low active and standby power to maximize battery life. The sensor operates from 300 mbar to 1200 mbar at temperatures up to 85°C and includes a 24-bit ADC providing 13 cm resolution at sea level. The MS5840-02BA includes a temperature sensor for compensation with data available to the user, and can be configured with conversion time as fast as 0.5 ms.

The sensor features a durable stainless steel cap that is gel-filled for water resistance.
