ABB JOKAB SAFETY has released a new line of Safety Contact Mats for safeguarding personnel around machines, presses, robots and other types of active equipment. Safety Mats are typically connected to a monitoring system and placed as a boundary around potentially hazardous equipment. When someone steps on a mat the surface triggers a control signal to the stop circuit of the nearby equipment. A switch design inside the mat assures that the equipment motion stoppage is immediate, providing a valuable layer of safety in industrial environments. The new JOKAB Safety Contact Mats, which feature a dotted polyurethane non-slip surface layer, are able to withstand the toughest industrial conditions and are impervious to oil, acid or caustic substances. The mats are available in standard sizes ranging from 12” x 12” up to 48” x 60”, and are commonly placed in sections around equipment. They can be affixed together and mounted to the floor with either aluminum ramp rails or integrated rubber ramp trim.
The mats consist of two conductive plates which are separated by a proprietary isolating layer, and are maintenance free. “The new ABB JOKAB SAFETY contact mats have been developed to reduce the costs associated with monitoring personnel inside hazardous areas, costs typically associated with safety laser scanners or horizontally mounted safety light curtains,” said Rich Gibson, ABB JOKAB SAFETY product manager. “These mats, built in the United States, are the perfect blend of economical design and extreme robustness for tough industrial applications.” Safety Contact Mats must be connected to a suitable monitoring unit (e.g. ABB JOKAB SAFETY safety relays RT6, RT7A/B, RT9, Vital with Tina 6A or Pluto Safety PLC). The monitoring unit monitors the functionality of the contact protection and detects any breaks or short-circuits in the lines. Several safety mats can be connected in series while still retaining the same level of safety. When pressure is applied, the active surface of the contact area in the contact protection is closed and the safety output on the monitoring unit trips. A stop signal will be sent to the machine’s safety circuits preventing any dangerous movements. Safety Contact Mats are used in a variety of industrial applications including machining centers, robotic work cells, automated cells, and conveyor transfer stations; and in commercial applications for automatic door opening and detecting the presence of people.
