Note 1. Output current measured over 250Ω load resistor.

Note 2. Output current measured over 500Ω load resistor.

Note 3. Output function trigonometrical (sine curve) ; ϕ = arcsin(Iout)

Note 4. Offset specified as Output @ 0°.

Note 5. Mounting accuracy depending. Position should be calibrated. See measuring positions.

Note 6. The cross-axis sensitivity determines how much acceleration or inclination, perpendicular

to the measuring axis, couples to the output. The total cross-axis sensitivity is

the geometric sum of the sensitivities of the two axises which are perpendicular to

the measuring axis.

Note 7. The output has true DC (0Hz) response.

• It is important that the part is parallel to the mounting plane, and that the output equals the zero value when sensor is in zero position.

• Please note the picture above which provides information on how the output of the accelerometer behaves in different circumstances when assembled.

Please also note that you can rotate the part around the measuring plane for optimum mounting location.
