Basically, there are four ways to achieve noise reduction:
Add a physical sound barrier
Install a vibration damper
Provide sound absorption
Metering the air flow
Only knitted wire mesh functions as all four of these types of noise reducers-economically and as a single-composite material.
Unlike metal baffle plates-which usually involve costly welded constructions and add significant weight-Metex knitted wire mesh noise-suppression solutions are light in weight and economical. Metal baffles can also slow the passage of air-in some cases resulting in reduced equipment operating efficiency due to generation of excessive back pressure. Porous materials such as foamed plastics and synthetic felts are highly susceptible to degradation at elevated temperatures-leading to eventual embrittlement and decomposition.
Knitted metals can be virtually custom tailored to specific needs of a given application. Engineered products can be fabricated from Metex by knitting one or a combination of widely diverse materials, such as all types of stainless steel, aluminum, copper, sophisticated alloys, synthetic polymers, fibers, and yarns. |

Optoelectronic safety curtains with visible light.
This innovative system is comprensive of a visible laser transmitter (650nm) and a receiver. The immaterial area created between Tx and Rx let the operator works in a safety environment.
Models:
Classic barrier with transmitter and receiver in two different columns.
Laser Barrier D with transmitter and receiver integrated in one column
and one column with mirrors.
Perimetral protection barrier system with deflection mirrors columns.
Advantages of our barriers:
- Thanks to the visible light they are very easy to align until 60m.
- They do not receive any influence from others artificial lights or from the sun-light.
- All our barriers works untile a range of 60m.
All our optoelectronic safety barriers are certified CE from the certifier NEMKO and are conforming to:
- 98/37/EEC Machine Directive
- 73/23/EEC Low Voltage directive
- 89/336/EEC Electromagnetic Compatibility Directive
- EN 61496-1 and IEC 61496-1-2 Electrosensitive protection devices. |

In comparison with conventional LED through-beam sensors, laser through-beam sensors are distinguished above all by the high accuracy of their optics. As a result, there is a precise switch point anywhere between the sender and the receiver. In addition, thanks to the narrowly focused beam, very small objects can be detected. Also impressive with the new Contrinex laser through-beam sensors are the long operating distance of 50 m and the high switching frequency of 5 kHz. Sensitivity setting is by means of a potentiometer. The sharply concentrated red laser beam (660 nm) simplifies alignment, since the light spot is clearly visible even at long distances and in ambient light. The devices are built into a short, robust M18 metal housing of stainless steel and have an excess light indicator.
Versions are available either with changeover outputs or with excess light output (light-ON). Contrinex laser switches are, moreover, particularly cost efficient. |

Application:
Optoelectronic safety device are used as entry, danger point or danger zone guards.
SLB range safety light barriers ar utilised as entry guards to dangerous areas. these protection devices operating without physical contact achieve Control Category 2 or 4 to EN 954-1 in combination with SLB 200-C or SLB 400-C safety monitoring modules.
Design and mode of operation:
On the SLB/SLC/SLG ranges of optoelectronic safety devices, the emitter and receiver are fitted in two separate enclosures. An invisible infra-red signal is sent from the emitter and this is picked up by the lens system of the receiver and evaluated either by an integral or external safety monitoring module. If the light beam is interrupted, the secure outputs are switched.
All of the optoelectronic safety devices listed here are maintenance-free and are characterised by simple fitting and adjustment.
