*1 The Analogue output linearity is ±2.5% of F.S. (The F.S. is 300 mm for the UD-310, 1300 mm for the UD-320, 6000 mm for the UD-360, and 3000 mm for the UD-330.)
*2 The display resolution cannot be 1 mm or less (1 cm with the UD-360) when converted to distance.
*3 The minimum detectable object displays the size of the object to be detected that satisfies the specifications listed above. Depending on conditions such as presence/absence detection, it is also possible to respond to even smaller objects. Contact KEYENCE for more information.
*4 The usable range is 20 to 30 VDC.
