Linearity

The linearity is the maximum deviation between the output voltage characteristics corresponding to the inclination angle and a standard straight line. The definition varies depending on the straight line and the deviation calculation.
The linearity of our inclination sensors corresponds to the independent linearity explained below.

Independent linearity

The maximum deviation between the standard straight line, with the position and inclination for which the deviation of the + side and the - side is the minimum within the detection inclination angle range, and the actual output voltage characteristics. It is expressed as a ratio of the standard straight line.
The standard straight line is defined as V=P(θ/θA) + Q ± C, with P as the specified inclination and Q as the intercept when θ=0. P and Q have been selected to keep C as small as possible.
θA is the detection inclination angle range.

Response time

Time required for the inclination sensor to reach 90% of its steady state when it suddenly changes its angle from ±25° to 0°.
The inclination change time is not included here.

Detection trigger inclination angle

Minimum inclination angle required for the inclination sensor to modify the output voltage.

Output (open drain)

The output MOSFET drain is an open type and can directly open and close currents of the rated load current and lower.
Be aware that if the load (between Vcc and OUT) short-circuits, and the switching type inclination sensor is switched on, the output MOSFET burns out.
When you use it as a voltage output type, connect a load resistance externally between Vcc and OUT, and use the voltage between GND and OUT as the control signal.
