6 Specifications of the LK-G Series
■
LK-G37/LK-G32
*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.
