*1 When alternate frequencies are set, the response time increases by approximately 20%.
*2 When using the IO-Link communication, if the response time is set in 1ms or more, it becomes approximately 10% slower.
*3 160 mA or less (at 10 V, with load)
*4 IO-Link: Specification v.1.1/COM2 (38.4 kbps) is supported. The setup file can be downloaded from KEYENCE website (
If you are using the product in an environment in which you cannot download files over the Internet, contact your nearest KEYENCE office.
*5 When the following small-diameter fiber units (the diameter of the cable is ø1.3 ø0.05" or ø1.0 ø0.04") are used, the IP65 rating cannot be satisfied (FU-4F/66/91/93/43/63/63T etc.). When any small-diameter fiber units except for the above are used, IP65 is applied.
*6 When the waterproof adapter A/B are not used at the time of installation of a small-diameter fiber unit, the IP65 enclosure rating cannot be satisfied.
