1Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
2Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.
3The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.
4Operating temperature range: The temperature range over which the sensor will produce an output proportional to force.
5Compensated temperature range: The temperature range over which the sensor will produce an output proportional to force within the specified
performance limits.
6Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the force range at 25°C [77°F].
Includes all errors due to force non-linearity, force hysteresis, and non-repeatability.
7Full Scale Span (FSS): The algebraic difference between the output voltage at full scale force and the output at zero force.
8Total Error Band (TEB): Combined error from calibration, accuracy and temperature effects over the compensated temperature range at 5.0 V from
15 %FSS to 95 %FSS.
9Long-term stability after 1000 hr of operation at 25°C [77°F].
