E3MC E3MC Precautions General Mounting Tighten the Fiber Unit with a screwdriver to a torque of 0.2 N·m. Do not impose any voltage exceeding the rated voltage on the E3MC, otherwise the E3MC may be damaged. Fibers When supplying power to the E3MC, make sure that the polarity Among the recommended fibers, the E32-CC200 and E32-D32L of the power is correct, otherwise the E3MC may be damaged.

E3MC E3MC Connection Installation Do not pull the Fiber Unit with force exceeding 9.8 N or press the Power Reset Time Fiber Unit with force exceeding 29.4 N. The E3MC is ready to sense objects from 100 ms after the E3MC The fiber is so thin that the utmost attention will be required to is turned ON, until when no devices connected the E3MC can be handle the fiber.
