15
The GuardShield Micro 400 is an economical three box (transmitter,
15
receiver, and controller) Type 4 safety light curtain offered in a small
profile (15 x 20 mm (0.59 x 0.79 in.)) housing.
17
The protective heights are offered from 50...1200 mm (1.97...47.24 in.)
21
in 50 mm (1.97 in.) increments. The compact housing size allows the
22
GuardShield Micro 400 to be mounted in areas where standard safety
24
light curtains must not be able to be mounted due to space constraints.
It is also possible to recess the GuardShield Micro 400 transmitter and
32
receiver into machine frames.
