Safety Mats & Area Guarding
UMA Series
UMA Safety Mat System
Heavy-duty two-wire or four-wire presence
sensing safety mats with quick disconnect
cables, perimeter trim and Cat. 3 controllers
System
When UMA series mats are combined with an
SCC-1224A,
MC3,
MC6, or other Omron programmable safety controller (with
complete diagnostics), the result is a system that meets the
standard EN ISO 13856-1 and is entitled to display the CE mark.
See below for an overview of the various components.
UMA Series Mat
•
IP65 rated
•
Single-piece molded polyurethane (PUR) construction
•
Black or yellow color
•
Easy cable connection
Controllers
• Safety category 3 devices
• DIN-rail mount (MC3)
• NEMA MC6 controllers
Trim
• One-part or Two-part perimeter and joining trim simplifies instal-
lation and provides a custom appearance
• Two options for trim kit corners: Mitered and molded
Note:
Trim options are unchanged from UM and UMQ series.
Identical sizes are backward compatible., except for metric trim kits,
which will no longer be made to the nearest half inch. UMA mats and
trim kits will now be made to their true metric dimensions.

Description
The UMA Mat System offers quick-connect M8 connectors on
the mat that easily conceal under the trim offering easier instal-
lation and quick replacement. The system can be used with
with the MC3 and MC6 4-wire controller; UMA mats can also be
directly connected to NX-S or G9SP programmable safety control-
lers eliminating the need to intermediate controllers.
Safety Mats are ideally suited to harsh environments where
devices such as laser scanners and light curtains can false trip
due to contaminants in the environment. Safety mats when used
as a start-up prevention device offer additional worker protection
offering continual detection in hazardous areas.
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
How the System Works
The operation of a UMA 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 two wires with a terminating resistor or four
wires to the controller providing the redundancy required to moni-
tor 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.

Trim Selection
Several choices are available in trim selection and can be customized to a specific application.
Two-Part Ramp Trim with Yellow PVC Cover (TKM):
- Ramp trim, aluminum base & PVC cover with mitered corners
- + / - 2.75 in. to mat layout dimensions
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 our exclusive molded corners.
Two-Part Ramp Trim with Aluminum Cover (TKAT)
- Ramp trim, two-part aluminium with mitered corners.
