Voltage - Supply : 3V~3.6V
Operating Temperature : -40℃~+85℃
Description : Force Sensors, Load Cells RoHS
Mfr. Part # : FMAMSDXX005WCSC3
Model Number : FMAMSDXX005WCSC3
The FMA Series are piezoresistive-based force sensors offering a digital output for reading force over the specified full scale force span and temperature range. They are fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and nonlinearity using an on-board Application Specific Integrated Circuit (ASIC). Direct mechanical coupling allows for easy interface with the sensor, coupling with tubing, membrane or a plunger, providing repeatable performance and a reliable mechanical interface to the application. These products offer a more stable output which is directly proportional to the force applied to the mechanically-coupled sphere. The FMA Series is available with pocket tape and reel packaging. They are designed to meet the customers need for a compensated, amplified force sensor which provides digital outputs, a variety of force sensing ranges, a small, cost-effective format, and enhanced durability and accuracy. The flexible design provides multiple standard configurations over a wide operating temperature range.
