The fibre-optic sensors of the TEC series offer a versatile and effective solution for the detection of objects, surfaces, register marks, or other references on the basis of their colour.
The diffused proximity optic system is based on a RGB (red-green-blue) LED emission; the received signal is elaborated and recognised by the microprocessor that also controls the output with a response time inferior to 1 ms. The sensors can recognise a precise colour, or various colours inside a chromatic range included between two references memorised during the setting phase. The output is activated every time the colour or memorised chromatic range is recognised.
Three patent-covered solutions are present: the RGB emission control and the amplifier’s thermic compensation guaranteeing the maximum sensitivity in detection; the transparent CLEARLOCK™ system allows the verification of the correct insertion and fixing of the fibre-optics, as well as the identification of the light sources.

Reduction of installation costs, space and time are only a few of the advantages offered by TED series, that presents two fibre-optic amplifiers inside a single housing with only a 12 mm depth, suitable for both fixing bracket or DIN rail mounting. The sensors have four input holes for the emission and receiver terminals of the two independent fibre-optics, that can be positioned either separately at long distances or close to each other without any interference. The EASYtouch™ setting push-buttons, the indication LEDs and the NPN or PNP outputs are all double and independent.
The power supply is in common for both channels, while the outputs are placed on different poles that can be connected together in parallel, obtaining an 'OR' function. This means that the common output is activated even if only one of the two fibre-optics has detected the object.
The TED sensors are available with cable or M8 connection.

The TEN series has been developed to guarantee the best performances with the extremely various plastic fibre-optic accessories. Different models are available: models with 1.5 kHz switching frequency for the longer operating distances, or 5 kHz models with only 100 ìs response time and double red/green selectable emission, that can be also used as contrast sensors to detect coloured marks.
The setting is obtained by means of a SET push-button and thanks to a tri-colour LED that guides the operations, signalling the correct optic fibre alignment. Moreover a 2 bit anti-interference system that, within the response time, uses another confirmation pulse before switching the output and a special highsensitivity amplification circuit to also detect transparent objects are present. The exclusive patent-covered CLEARLOCKTM solution allows the visible verification of the correct fibre-optic insertion, as well as the identification of the light sources.

The VLL 18T photoelectric switches are suitable for our LL 3 series. They provide strong performance and simple handling.
The features in brief:

• Large ranges (throughput system to 200 mm (1000 mm), scanner system 55 mm (90 % remission)),
• simple sensitivity setting,
• flexible, simple and dependable fibre-optic cable adaptation.

A strong team is created with a clever range of fibre-optic cables:

• VLL 18T and LL 3 fibre-optic cable series. Small mounting space, smallest assembly dimensions, flexible positioning, increased temperatures, chemical resistance, etc. - a suitable plastic LL 3 fibre-optic cable is the solution. M 18, compatible housing for many solutions with appropriate basic principles in terms of physics: optoelectronic, inductive, capacitative and magnetic.

A few details about the VLL 18T: Sensitivity setting

• manual per Teach-in button
• electronic per control input C.

Flexible and minimum variants in spite of this: Freely selectable switching type light-switching (L.ON) or dark switching (D.ON) per control cable. Visible red light; VS = 10 ... 30 V DC; switching output Q either in PNP or NPN; M 12 plug or cable, IP 67 and sturdy metal housing are additional VLL 18T system strengths.
Special focal points are applications in the branches:

• Packaging industry,
• semiconductor and electronics assembling,
• assembly and handling technologies,
• special mechanical engineering tasks.

The WLL160 photoelectric switch for fiber-optic cables with switching point setting, manually per potentiometer or automatically per Teach-In at the push of a button, rounds out the W160 series. Plastic fiber-optic cables of the LL3 series in approx. 90 different options are available as accessories.

The sensor, with a variety of adjustable features including teach-in for a fast set-up, is ideally suited to a wide range of applications Glass and stainless steel fibre-optic cables open up new areas of application in restricted environments.
