Pressure-sensitive safety edges are flexible strips that can be mounted to the edge of a
moving part—such as a machine table or powered door—that poses a crushing or
shearing risk. Contact of the edge with an object or personnel switches off the machine
hazard. Safety edges are a cost-effective solution for constant safety monitoring in smaller
areas, especially those applications requiring physical flexibility and a tight turn radius.
Rated to Category 3, safety edges do not develop ‘dead spots’ like some other pressure-
sensitive safety offerings. They are also easy to install and maintain, and can withstand
high-pressure washdowns, making them suitable for a wide range of applications and
environments. Multiple profile sizes and the availability of custom edge systems also lend
to a high degree of application flexibility. It is important to note that Safedge requires a
dedicated safety relay for monitoring and control, which can be connected to other safety
systems.
Safedge™ Pressure-Sensitive Safety Edges
Pressure-sensitive safety mats provide constant guarding and monitoring of a floor area
around a machine; 66 lbs. or more of pressure on the mat (e.g., an operator’s footstep)
causes the mat controller unit to switch off power to the hazard. Like safety edges,
MatGuard safety mats are easy to apply and maintain, can withstand high pressure
washdowns and are not susceptible to dead spots. An ideal solution for relatively small
areas, MatGuard products also offer a high degree of application flexibility, offering
reversible mats, direct micro quick connectivity to controllers, simple connection to
standard and DeviceNet Safety I/O blocks, custom system configurations, and quick-
delivery standard sizes. However, mats can be damaged by dropped objects, such as tool
dies, and pose a potential trip hazard if trim is not used.
MatGuard™ Pressure-Sensitive Safety Mats
The SafeZone safety laser scanners are opto-electronic devices that create a user-
configurable scanning field with one or more safety zones. If a person or object enters the
warning field, the SafeZone scanner switches a single output that can be used to initiate a
warning signal, such as an optical or acoustic alarm. If the inner safety field is breached,
the scanner switches two independent safety outputs initiating a machine stop signal to
halt dangerous machine motion. Offering warning fields up to 49 meters, the SafeZone is
easy to install—either horizontally or vertically—and requires no dedicated controller for
operation. Suited for Category 3, SIL2 PLd applications, the scanner is easily interfaced
with other safety systems and the easy-to-use configuration software allows
customization of the field shape.
