Example:
■Fiber-Optic Cables
The E3X-NA amplifiers use Omron’s E32-series fiber-optic
cables. With a choice of over 80 sensing heads, you are sure to
find one that matches your application requirements. Refer to the
selection of E32 cables (listed with their respective sensing
distances) in the fiber section at the end of this data sheet. Order
fiber-optic cables separately.
