CHARACTERISTICS (TYPICAL)
■ LB-301/LB-1201(W): 300 mm ± 100 mm
Shift-point adjustment range Span adjustment range
Changes in detection span when target is tilted
The shift-point adjustment range shows the range where the output
voltage reading can be shifted to zero using the SHIFT adjustment
trimmer (operates when DIP switch 4 is set to LOCK). The AUTO
ZERO function (operates when DIP switch 4 is set to FREE), allows 0.V
resetting at any position within the measuring range.

RESPONSE speed selector switch set to HIGH
RESPONSE speed selector switch set to MID
RESPONSE speed selector switch set to LO
■ Interference range*
* Use of the interference suppression function enables close mounting
of 2 sensors. Since sensors “X” and “Y” alternately emit a laser beam
at 30 Hz, interference does not occur. (Target: white paper)
