6 Specifications of the LK-G Series
■ LK-G35/LK-G30
*1 When the sampling rate is 20 µs, the value becomes +1.8 (FAR side) to –5 mm (NEAR side) at the
time of the diffuse reflection, and +1.6 (FAR side) to –4.5 mm (NEAR side) at the time of the spec-
ular reflection.
*2 The value when measuring the KEYENCE standard target (ceramic) in the standard mode
*3 The value when measuring the KEYENCE standard target (SUS) 4096 times average at the
reference distance.
The value in parenthesis ( ) indicates the typical value when measured with the number of
averaging times of 16384.
