When mounting the sensor and controller, use normal precautions for handling
electrostatic sensitive devices. The EX USB controllers have internal protection to ±27
kV for ESD discharges to the sensor (not to the controller directly) that may occur during
normal operation of the sensor. Refer to the appendices for further specifications.
The EX USB controller requires a 3M™ MicroTouch™ USB communication cable (P/N

connector (JP1) on the EX USB controller. The other end plugs into a USB port on your
PC with a Type-A connector. Table 1 describes the interconnections of the 3M™
MicroTouch™ USB cable.
