Photo-electric barriers to liv. 4 with a special "T" and "L" for applications to palletizing and packaging machinery.

Safety barriers 4500 series has been designed for the protection of entrances and exits of highly automated machines in order to allow access to materials to be processed, maintaining the guarded entrance to protect operators from an inadvertent movement in the danger zone while the machine is running.

Barriers B series of level 4 with resolution 14 mm. and blanking.

These units with PNP static output to be connected directly to PLC or to personal security for the relay output.

The possibility of blanking is useful in machine processing of sheet metal where you need to automatically delete the rays so as not to interfere with the operation of the machine.

Barriers for optical detection area number NS-1
The system, consisting of a transmitter and a receiver generates a grid of parallel rays can detect the presence of objects, determine the shape and position, transmitted to the control system. Provides a signal 2xPNP.
The heights of detection are between 100 and 2000 mm with flow of 0.6 m, 2.5 m, 15 m, 30 m.

Barriers for optical detection of the shape and position of the NS2 Series

• type NS2-1 with output 4-20 mA
• type NS2/2 with output 0-10 volt
• type NS2/3 with output 232
• type NS2/4 with output 485

Are made of a special PVC sheath within which is housed the sensor element which provides an electrical signal when any external crushing action is exerted on the board. A profile of aluminum plate complete the device for its attachment to the machine.

These devices are designed to prevent injury to personnel against crushing by moving parts as sliding doors, gates, elevators plans etc. detecting an electrical contact via a control circuit.

The system is guaranteed for a security level 1 or 3 "FAIL SAFE" in accordance with the use of control units and the number of conductors connected to the ribbon switches.

Are made of a special rubber sheath within which is housed the sensor element which provides an electrical signal when any external crushing action is exerted on the board. A profile of aluminum plate or angle the device to complete its attachment to the machine. These devices are designed to prevent injury to personnel against crushing by moving parts as sliding doors, gates, elevators, etc. plans. detecting an electrical contact via a control circuit. The profile of the sheath is designed to ensure reliable performance even at the slightest pressure, both on top and on one side.

The system is guaranteed for a security level 1 or 3 "FAIL SAFE" in accordance with the use of control units and the number of conductors connected to the strip. These edges are available in a wide range of materials.

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 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.

Are normally used as shockproof means of transport and self-propelled machine which may inadvertently invest staff. Their job is to absorb the shock and produce (when crushing) a signal for the immediate arrest of the car. Consist of a block of foam shaped to the customer's design with embedded sensors formed by strips Electro-sensitive.
Are made in standard forms or a parallelepiped according to customer needs.

The range of control units, "PS" is available in two models:

• type PS-1 for low-risk level 1
• type PS-3 level 3 Fail-safe

They may control a number of devices having the following characteristics:

• maximum edge length = 60 meters
• maximum carpet area = 15 sqm.

Switch on-off level has been made to control the level of liquids in tanks, tanks, silos, etc.., Up to a pressure of 30 bar and a temperature of 200 ° C with the ability to remotely send a signal.

The device consists of:

• a threaded rod (plastic or stainless steel) inside which is housed a switch "reed"
• where a floating impregnated magnets

With the change of level the float transmits an electrical signal referred to the characteristics attached.

These devices are miniaturized type waves can be used in very tight spaces and facilities are provided for vertical and horizontal contact with reversible by NOa NC. Are used in industrial applications where it is required a reliable product with a value for money really competitive.

The new series of flow produced by Meister Germany (treated exclusively in Italy by Grein), find wide application in the field of fluidics for control and automation of industrial plants.

These devices made on the basis of the German VDE standards and built with advanced technology able to meet every requirement, offering the utmost reliability.

Usually these products are used to control the passage of a liquid or a gas and then pass at a distance an electrical signal if you experience a change in scope.

The switch "DRY REED" alarm is sealed in a watertight IP65 protected against impact and corrosive environments. The range of equipment provides flow rates from 0.1 to 150 l/ min with bodies made of brass or nickel-plated or in AISI.

The new series of flow Sika processed exclusively for Italy by Grein have found wide acceptance in the domestic and foreign manufacturers for control and automation of industrial plants.

Equipment is a German production made on the basis of V.D.E. and built with advanced technology able to meet every requirement, offering the utmost reliability.

These products are normally used to control the passage of a fluid or a gas and then pass at a distance an electrical signal, if there is a change in scope.

The switch "DRY RED" alarm is sealed in a watertight IP65 protected against impact and corrosive environments.
The range of flow switches includes various courses offered related to water, oil etc.. realization of the body with brass and stainless steel 316 (depending on the compatibility of the fluid).
