July 28, 2014 - Designed for ambient pressure measurement, SM6842 is available in absolute pressure range of 15 psi and comes in SMT housing with 5 x 6 mm², JEDEC-compliant, SOIC-8 footprint (including leads) that fosters straight-forward PCB design and assembly. Height of 7.6 mm (to top of vertical port) provides flexibility in space-restricted designs, while 127 mV typ output allows for signal-conditioning customization. Operating from -40 to +125°C, product supports up to 10 V supply.

SMI Introduces MEMS Pressure Sensor for Ambient Pressure Measurement

Silicon Microstructures, Inc
1701 McCarthy Blvd
Milpitas, CA, 95035

Press release date: July 24, 2014

Milpitas, California — SMI (Silicon Microstructures, Inc.), a global leading developer and manufacturer of MEMS (Micro-Electro-Mechanical-Systems) pressure sensors for over 23 years, introduces the SM6842 MEMS pressure sensor designed especially for ambient pressure measurement and available in an absolute pressure range of 15 PSI (103kPa). The pressure sensor housing is based on standard surface mount technology and features a JEDEC compliant SOIC-8 footprint for straight-forward PCB design and assembly. The small footprint is 5 x 6 mm2 including the leads with a height of just 7.6 mm to the top of the port providing flexibility in space challenged designs with a typical 127 mV output for signal-conditioning customization.

The SM6842 with a vertical port enables interfacing with tubing or manifold designs for industrial applications to measure ambient pressure or space-constrained medical applications in Negative Pressure Wound Therapy (NPWT). The SM6842 is especially designed for OEM applications enabling cost-effective, large volume manufacturing. With a protective gel, the SM6842 enables the following applications:

• Ambient Pressure Measurement
• Hand-held Gauges
• Digital Pressure Gauges
• Environmental Monitoring
• Compressor Controllers

• Negative Pressure Wound Therapy (NPWT)
• Surgical & Respiratory Equipment
• Barometric Correction
• Pump Controllers

• Appliances
• Sports Equipment
• Altimeters

• Operating Temperature Range: -40oC to +125oC
• Output: 127 mV @ 5V, 15 PSIA
• Voltage Supply: Up to 10 Volts
• Complies with RoHS and REACH requirements

“The ultra-small SM6842 provides customers with great design flexibility and performance for cost-sensitive and space constrained designs in the industrial, medical and consumer markets,” notes Omar Abed, President and CEO at SMI Pressure Sensors. “As SMI looks to continue its push to innovate and expand its offerings to customers, we are excited to offer the smallest, ported pressure sensor in the market!”
