^1 Sensor head and optical unit are a matched pair. Not cross compatible. ^2 Value measured in displacement mode with KEYENCE reference workpiece (mirrored surface). ^3 Value measured using 16,384 average cycles with KEYENCE reference workpiece (mirrored surface). ^4 The enclosure rating is equivalent to IP50 when the included sticker is attached. ^5 Operation verification has been performed in environments of 10^-6 Pa. ^6 These figures are based on the case where a jig made of SUS303 (or SUS304) is fixed between the head and the object.
