Description
The Allen Bradley Guardmaster GuardShield Safe 4 is an
economical two box, Type 4 safety light curtain with ON/OFF
functionality. This basic, guard-only operating mode, safety light
curtain has an Integrated Laser Alignment system that simplifies the
alignment of each pair of light curtains. Visible laser beams are
activated by touching the finger symbol on front face of the light
curtains. Positioning of the transmitter and receiver laser beams to
their respective targets facilitates optimal alignment of each Safe 4
pair. The Integrated Laser Alignment system also quickly helps with
the re-alignment of pairs when units are knocked out of alignment
during the course of the work process or when corner mirrors are
used.
The GuardShield Safe 4 is designed to be used in a variety of
applications across a broad range of industries in medium to heavy
industrial environments. Offered with shock isolator kits for shock
and vibration applications and protective heights from 120…1920
mm in 120 mm increments assures that the correct size of safety
light curtain is available to suit the application requirement.
The GuardShield Safe 4, with an environmental rating of IP65, meets
all applicable global standards and can be used on or around
industrial machinery and equipment anywhere in the world.
