^*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 IO-Link: Specification v.1.1/COM2 (38.4 kbps) is supported. The setup file can be downloaded from KEYENCE website (http://www.keyence.com).If you are using the product in an environment in which you cannot download files over the Internet, contact your nearest KEYENCE office.
^*4 IO-Link: Specification v.1.1/COM2 (38.4 kbps) is supported. The setup file can be downloaded from KEYENCE website (http://www.keyence.com).
If you are using the product in an environment in which you cannot download files over the Internet, contact your nearest KEYENCE office.
^*5 160 mA or less (at 10 V, with load)
^*6 When the following small-diameter fiber units (the diameter of the cable is ø1.3 or ø1.0) 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.
^*7 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.
