*1 Use a cable of 30 m or less.
*2 When the Power Mode is set to HIGH SPEED, 100 mW (4.0 mA) will be added.
*3 About the enclosure rating when a small-diameter fibre unit (the diameter of the cable is ø1.3 or ø1.0) is used. IP66/IP65 cannot be satisfied when the type whose diameter is ø1.3 and terminal can be separated (FU-4F/ 66/91/93/43/63/63T etc.) is used. When any small-diameter fibre units except for the above are used, IP65 is applied.
*4 In any of the following cases, the enclosure rating IP66/IP65 cannot be satisfied.
When the Fibre Unit and KEYENCE's M8 connector cable are not connected (Recommended conditions to tighten up the M8 connector: Tighten it by hand first.Then retighten it as much as 1/16-1/8 of a rotation with pliers.)
When the Fibre Unit and KEYENCE's M8 connector cable are not connected
When the dust cover of the Sensor Amplifier is open
When there is debris in the dust cover
When the waterproof adapter A/B are not used at the time of installation of a small-diameter fibre unit.
