6 Specifications of the LK-G Series
■
LK-G87/LK-G82
*1
The value when measuring the KEYENCE standard target (ceramic). When the sampling rate is 20
µs, the value becomes –9 (NEAR side) to –15 mm (NEAR side) at the time of the diffuse reflection,
and –8.7 (NEAR side) to –14 mm (NEAR side) at the time of the specular 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.
