6 Specifications of the LK-G Series
■
LK-G407/LK-G402
*1
The value when measuring the KEYENCE standard target (ceramic) in the standard mode. When
the sampling rate is 20 µs, the value becomes –70 (NEAR side) to –100 mm (NEAR side) at the
time of the diffuse reflection, and –70 (NEAR side) to –99 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.
