Instruction manual
Note: 1. When
using the M8 models within the temperature range from 70
°
C to 85
°
C, the voltage range must be from 10 to 30 VDC and
control output (switching capacity) must be 100 mA max.
2. The
response frequency of the DC switch section is an average value. Use
standard sensing objects, provide a distance of twice the
standard
sensing object distance between sensing
objects, and provide a setting distance of half the sensing distance as measure
-
ment
conditions.
