Description
The Allen-Bradley Guardmaster GuardShield safety light curtain is
an economical, fully featured, Type 4 safety light curtain in a
uniquely styled housing. GuardShield safety light curtains are general
purpose presence sensing devices designed for use on hazardous
machinery providing point of operation, as well as perimeter and
access guarding. This self-contained, two box, safety light curtain has
DIP switch selectable operating modes and are available in both
14mm and 30mm resolutions.
Modes of operation such as fixed and floating blanking, beam
coding, start/restart interlock, external device monitoring (EDM),
machine test signal, are selected by dip-switches settings. These dip-
switches are located beneath a security door, which are conveniently
located on both the transmitter and receiver end caps.
The GuardShield’s torsionally rigid, extruded aluminium,
polyurethane powder coated housing, combined with an
Environmental rating of IP65, allows the GuardShield to be used in
guarding applications across a broad range of industries.
