MS5839-02BA Ultra-compact, chlorine resistant, digital pressure and temperature sensor Miniaturization, performance and precision are key for sensors embedded in consumer devices like swim watches and diving equipment. Expanding on TE Connectivitys (TE) portfolio of ultra-compact digital altimeters, our MS5839 2 bar model is designed to meet the next generation of device manufacturer designs and challenges. TEs MS5839 is an ultra-compact (3.3 x 3.3 x 2.75 mm) digital altimeter that is optimized for applications where chlorine and saline are present. The robust, gel-filled design of the MS5839 enables operation in harsh media environments while providing accurate and reliable digital measurements. This MEMS based sensor offers advanced water resistance, chlorine resistance, shielding, low power consumption and digital interconnectivity in an ultra-compact, low profile package. The board level design delivers sensing accuracy for both pressure (0.5mbar) and temperature (2C) measurements. Take your devices to the next level with the MS5839-02BA.
