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

safety mats.

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.

Functionality and advanced features
POINT OF OPERATION CONTROL (POC)
POC safety light curtains are typically designed to detect the presence of a nger
or hand. These devices are usually positioned in front of the point of operation
hazard, close to the machine opening. However, they may also be used for
perimeter guarding applications. They can be mounted vertically or horizontally.
PERIMETER ACCESS CONTROL (PAC)
PAC safety light curtains are used as whole body detection devices for detection of
personnel or large objects when they pass through the sensing eld. They are typically
positioned around an area or in front of a process entry or exit area. Typically they do
not require frequent interaction between personnel and the hazard during regular
operation. Multi-sided access control is attained through the use of corner mirrors.
AREA ACCESS CONTROL (AAC)
AAC uses a single-beam emitter and receiver unit to create a protective barrier
around hazardous machines including robotic cells, transfer stations, palletizers
and loading machines. Two-beam or multi-sided access control is attained
through the use of corner mirrors.
CASCADED SAFETY LIGHT CURTAINS
With a single cascaded light curtain system, the user can safeguard two adjacent
points of entry. Using the cascade conguration, up to four pairs of light curtain
segments can combine to offer protection in different planes. Often cascaded
safety light curtains are used to combine vertical protection against reaching in with
horizontal protection to detect someone standing behind the vertical light curtain.

FIXED AND FLOATING BLANKING
The blanking function is a means of disabling one or
more sections of a POC light curtain’s sensing eld.
There are two blanking modes: xed for static and
Press
Brake Die
oating for moving disabled sections.
MUTING
This function allows access for parts or objects to enter a hazardous area without
stopping the machine. However, if a person enters the dangerous zone, the
machinery will stop.
