Perimeter Switch Mats, are devices which are used to guard the ﬂoor area around an unsafe zone. They can be used to provide primary guarding where other type of guarding may be inﬂexible or impractical and also to provide secondary guarding i.e. they can be used in conjunction with an interlocked fence or light curtain to protect awkward shaped machinery. In essence, to provide presence-sensing of operators for as long as they remain inside a unsafe area.
Mats can be supplied in a variety of configurations to suit different machine sizes and locations. Please call for a custom quotation to suit your needs.
The Perimeter Switch mat operates when pressure (usually from an operator’s foot) is applied to the mat surface.
The result is a signal being to the safety mat controller which in turn will send a stop to the machine control system. The dimensions and the positioning of the mats should be installed in accordance with local and state guidelines. The aluminium edging is be used to ﬁx the mats in position on the ﬂoor.

PERIMETER CONTROL BOX (PS3A5) 24V.DC
The Perimeter Control Box is the controller for sensitive sensors provided with four wires (fail-safe condition) to meet category 3, as given by EN 954.At the open circuit of switch edge, mat, bumper in normal condition, the two relays are ON, while the pressure on the sensor causes the relays OFF. The interruption of the cable or the sensor, are detected in OFF condition of two relays, as the short circuit of the contacts of one relay. For this reason the circuit is named “fail-safe” and meet category 3 as EN 954.
The mats are a product of high quality encapsulated between two layers of vinyl resin with special additives in carbonto give greater abrasion resistance to ensure an IP65 sealing and high resistance to external agents such as water, oils, mineral salts, acids, dust.
They are very resistant to shock, vibration and flammability as a self-extinguishing. The platform is provided in any size and shape. A profile of aluminum particular section and a ramp of 20° is used for attachment to the floor.
