Description
An Omron STI Universal Mat system (UM series mat combined
with an MC3, MC4 or MC6) offers a simple method for guarding
personnel around hazardous machines. A Universal Mat system
offers freedom, flexibility, and reduced operator fatigue when
compared with traditional guarding methods such as interlocked
fences, pullback restraints or perimeter barriers.
Full visibility of and access to the work area is maintained. There
is no need to worry about personnel forgetting to replace mechani-
cal barriers or close gates.
how the System Works
The operation of a Universal Mat system is easy to understand.
The mat is a simple, normally open switch. When a specified
minimum weight is applied to the mat the "switch" closes. This
sends a signal to the controller which, in turn, sends a stop signal
to the guarded machine.
Each mat presents four wires to the controller. This provides the
redundancy required to monitor the wiring for open circuits due to
incorrect wiring or physical damage to the wires.
In order to meet many national safety regulations, Omron STI
offers trim to secure the mat to the floor so that it cannot be easily
relocated and therefore become ineffective.

Um Series
Safety mats & Area guarding
Applications
Presence sensing safety mats are used to monitor an entire
hazardous area. They offer flexibility, quick access and may
frequently be the most economic choice. Other options for
perimeter guarding include interlocked barrier guards and safety
light curtains. However, personnel can become trapped inside a
barrier guard and safety light curtains only monitor the perimeter,
not the hazardous area inside.
Additionally, mats can also simplify routine tasks such as
machine setup, maintenance and repair.
Applications can be
found throughout industry
and typically include the
following areas:
• Welding Robots
• Assembly Machinery
• Material Handling
• Packaging Machinery
• Punches
• Presses
• Robotic Work Cells

Safety mats & Area guarding
trim Selection
Several choices are available in trim selection and can be
customized to a specific application.
Aluminum Blunt trim
Used to finish off the edge of a mat installation near a wall or
machine. Helps hold mats in place.
two-Part ramp trim with Yellow PVc cover
This trim simplifies routing of cables and replacement of dam-
aged mats. To position the mats correctly, place all of the mats in
the approximate position, place the joining trim between the mats,
then temporarily place the cover on the joining trim. Square the
mats by sliding the ramp trim under the mats. When all of the mats
are correctly positioned, anchor the perimeter trim to the floor.
After the wires have been routed, a rugged cover of highly visible,
safety yellow PVC is snapped into place. Corners can either
be mitered or be Omron STI's exclusive molded corners. (See
illustrations on this page.)
Aluminum ramp trim
This single part aluminum ramp trim is available for areas where
the two part ramp trim may not be suitable.
molded corners
Eliminates the need to miter the corners of perimeter trim.
Designed to mate with Omron STI two-part ramp trim.
two-Part ramp trim with Aluminum cover
f
This trim is the same as above except that the PVC cover is
replaced with an aluminum cover that is attached by screws to the
base. (See the Dimensions Section of this datasheet for details.)
two-Part Active Joining trim
Similar in concept to the two-part ramp trim, this trim provides
an "active" joint where the perimeters of two mats adjoin each
other. When a person steps on the surface cover of the active
joining trim, the Universal Mat system will detect their presence
and send a stop signal to the guarded machine.
