Smart safety solutions that enhance productivity
Rockwell Automation takes safety seriously
Allen-Bradley® GuardShield™ presence sensing safety devices from Rockwell Automation help protect personnel and
equipment by detecting the presence of people and objects within a guarded area around machinery. Presence sensing
safety devices are ideal for applications where personnel need frequent and easy yet safe access to hazardous areas such
as near robotic welding, machining centers, stamping, hydraulic presses, lter presses or packaging equipment, etc. Our
range of presence sensing safety devices cover basic on/off functionality to more advanced features including blanking
and muting, all of which are available with CIP Safety over EtherNet/IP™ connectivity. Whether the need is nger, hand or
whole body detection, our knowledgeable team of experts understand how to apply a comprehensive safety solution for
your manufacturing facility.
Built to global standards for high reliability, stability and quality, Rockwell Automation solutions are ideally suited for
applications where personnel safety is a priority. Our innovative products and services help protect your people,
machinery, and environment while maximizing uptime.

SAFETY APPLICATIONS
GuardShield™ safety light curtain with two retroreective muting
sensors allows work cell access without stopping all processes.
1
This design allows an operator to enter the work cell to remove
and replace material.
Safety light curtain with corner mirror provides perimeter
guarding for the work cell. This conguration allows elimination
2
of fencing or hard guarding and offers detection of personnel
if they interrupt the sensing eld.

Note: Representative applications only. Actual solutions may vary.
MatGuard™ pressure sensitive safety mats around the entry
area of a machine process help to detect the presence of
5
personnel inside of the work cell.
Gate interlock safety switches help to stop hazardous
motion inside of the work cell if personnel attempt to
6
enter through the gate area.
SafeZone™ safety laser scanners mounted horizontally provide
area detection inside the work cell. Safety laser scanners can

be easily congured to scan irregular areas inside of the work

The SC300 safety sensor is used for hand detection
at a hazardous machine access point of the work cell.

The SC300 is a reective safety sensor that creates a
detection plane in openings of various shapes and sizes.
A Safedge™ pressure-sensitive safety edge is mounted
to a moving piece of machinery such as the bottom of a
8
powered garage door to prevent personnel from bodily
injury. Light pressure from any direction through 90°
on the prole will trip the system.
