Items of Note:
When the sensor is lying flat and only acted on by g-forces, the cylinder will be in Location C.
Upon startup and when lying flat, the sensor remains in the last location before shutdown. Once
movement is detected, the sensor will respond normally.
Pin Definitions and Ratings
Pin Name Type Function
1 OUT2* O Output state of phototransistor 2
2 Vdd* P Supply Voltage -> 3.0 - 5.5V
3 GND G Ground -> 0V
4 GND G Ground -> 0V
5 Vdd* P Supply Voltage -> 3.0 - 5.5V
6 OUT1* O Output state of phototransistor 1
Pin Type: P = Power, G = Ground, I = Input, O = Output
*Note: Maximum output signal voltage approaches power supply voltage.
