The EFESTO4 and KEEPER light curtains are optoelectronic systems with multi beams (ESPE) type 4 for the protection of body to prevent accidents on the machine on dangerous plants in accordance with International safety standards.
EFESTO4 and KEEPER are formed of an emitter and a receiver unit synchronized through a optic link. The safety outputs are solid state with the possibility to convert them into outputs relays using the optional modules. Are available interconnect modules to interface directly with the barrier without going through the electrical cabinet.
The wide range of model permit the employ on every field of industrial automation supplying the protection of the fingers, hand, arm, body, for the movement on dangerous area.

To complete the offer are available many accessories as:

• acrylic protection to render watertight barriers (IP 67);
• mirrors and floor posts for perimeter protection;
• connection cables;
• brackets for installation of the curtains;
• interface modules for transforming solid state into safety power relay outputs.

The safety edges are made in a durable material within which is housed the sensor (NO contact) which provides an electrical signal when any external pressure action is exerted on the ribbon switch. A profile of aluminum completes the device for its attachment to the machine. They are in a range of different profiles and sensitivities to suit various applications, perimeter protection, angular protection and other. The edges can be supply by special design of the customer. The housing material is EPDM or NBR. The connection with control unit are with two wire for non-safety application, two wire with internal resistor or four wire for safety application. They are also available in do-it-yourself kits for field fabrication and installation. The safety edges are compliant with EN 13856-2.
The edges in combination with PS3 control module can reach the CAT 3 - PL “e” how indicated in the ISO 13849-1 standard.

To choose the right bump switch for the application required, consider the following characteristics which define performance:

• Application, finger detection or other part of body detection.
• Activation force before closing of the internal contact.
• Internal contact activation after activation force.
• Overtravel distance after the contact closure

The mats are a product of high quality encapsulated between two layers of vinyl resin with special additives in carbon to 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 mats can be supplied with any shape and dimension (also circular) as requested by the customer. An aluminum edge is be used to fix the mats in position on the floor. The connection with control unit are with two wire for non-safety application, two wire with internal resistor or four wire for safety application. The termination of the connection cable can be with M12, M8 connector or free wires.

The mats models are:

• TO - Standard type in bubble black color in PVC
• TX - Standard type circular in bull PVC
• MO – Standard type plus aluminum protection cover
• MZ – Standard type as MO plus zinc metal sheet on the bottom

The MZ mat is used where the surface of the floor is not uniform. The TX mat is used inside circular doors of banks, shopping centers and other. The mat can be supplied with one or two sensitive areas.

The safety mats are compliant with EN 13856-1. The mats in combination with PS3 control module can reach the CAT 3 - PL “e” how indicated in the ISO 13849-1 standard.

They are utilized to prevent collision of the operator against vehicles or movement machines. The bumpers are able to absorb the impact and to produce a signal to stop the machine. The operating principle is very simple. With a minimum compression of the bumper, after a pre-travel, the internal contact produces the command signal for stopping the machine. After the pre-travel the bumper allows yet to compression (over-travel) that permit to cushion the impact of the person against the machinery. This sensing device utilizes a highly durable and flexible thermoplastic material which when pressed, closes the internal sensors. They are formed by a polyurethane foam (designed under customer drawing) with ribbon switches incorporated inside. The bumper is designed for fail-safe circuit to ensure proper monitoring of the system.

The safety bumper is compliant with EN 13856-3.

Are devices for industrial and civil applications requiring the detection, measurement and recognition of variously shaped objects.

The NI series are realized to detect object starting from 0,9mm diameter. Due to the principle of operation, is very effective the detection of flat sheet of small thickness of any kind of material. The detection is not dependent from material type and colour. Are so suitable to detect plastic, metal, wood, and in many cases glass and other transparent materials.

There are two output. If there is a +24V the light curtains beams are busy, otherwise if the beams are free the output is 0V.

The NS series are systems formed by a transmitter and a receiver that produces a zone of parallel beams to detect the presence, the form and the position of an object and communicate it to the control system. Different outputs and communication systems are available. The version with analogue output provides a voltage or current variation (0-10 V or 4-20 mA. The version with RS485 serial interface Mod-Bus protocol and give the indication of the status of every beam. Especially used in painting plants, lapping and where is important to know the location, size and holes in the workpiece.
