TE Connectivity’s SMI SM923X Series

TE Connectivity’s SMI SM923X series ultra low pressure digital sensor

The TE Connectivity’s SMI Pressure Sensors SM923X series ultra low pressure digital sensor have been developed to meet the challenging reliability requirements of the industrial, HVAC and medical applications. TE Connectivity’s SMI’s compact solution replaces traditional bulky and costly equipment and the SM923X series improves system efficiency with accurate and reliability performance. The total accuracy error after board mount and system level autozero is less than 1% full scale over the entire compensated temperature range. The 16 bit resolution provides the ability to resolve signals as small as 0.0038Pa. The excellent warm-up behavior and long-term stability further assures its expected performance over the life of the part.

The SM9233/SM9235/SM9236 are digital, ultra-low pressure sensors offering state-of-the-art MEMS pressure transducer technology and CMOS mixed signal processing technology to produce a digital, fully conditioned, multi-order pressure and temperature compensated sensor in JEDEC standard SOIC-16 package with a dual vertical porting option. It is available in a gauge pressure configuration.

3M has presented New 3M™ 100G QSFP28 Direct Attach Copper Cable Assemblies, 9Q Series are passive copper cable assemblies which utilize 3M Twin Axial Cable technology to create a highly-flexible, foldable, high-performance solution.
