Wiring Diagram & Connector Pin Out
Figure 2 User Socket Connector Pin Out
The sensor's cable is installed at the factory and is not removable or replaceable by the user. The
cable extends 8" outside of the case, contact LadyBug for other options. The 10 wire ribbon cable
exits the housing adjacent to the USB connector. With option SPI, a standard USB cable can also
be connected and the sensor will function as a USB sensor when SPI is not enabled.
The SPI/I2C connector end is a Samtec FFSD type (or equivalent) keyed 0.05" pitch two row
connector. Recommend 0.05" pitch IDC mating connector:
Samtec ESHF-105-01-L-D-TH (Vertical through hole);
Samtec ESHF-105-01-L-D-SM (Vertical surface mount);
Samtec ESHF-105-01-L-D-RA (Right Angle);

Other equivalent connectors are available. Note that the sensor's cable connector has a strain
relief and requires a socket accordingly.
