The SG1 is a light grids series with a wide range of applications. The light grids are available in a water resistent IP67 housing to be used in applications where moist-. water- and dust accumulation could cause problems for other light grids. This is the case in the sliding door of a bus where rain could be a hindering obstacle for many sensors, but not with the SG 1 light grids. The sensor looks through the layer of sawdust because of the so called excess gain which adjusts the strength of the signal to observed pollution.

The housings are available in different profile heights up to 2.1 m. The beam pattern and the resolution guarantee that the light grids have a big coverage within the detection area between the emitter and receiver. This ensures that also small objects that pass the light grids are detected. The SG1 light grids can be used in moving application such as in a moving door with a passage width up to 4 meter!

For extreme applications there are the SG10 light grids from Telco. With a range from 10 to 14 meters it is able to be used in applications where emitter and receiver are placed far from each other such as big hangar doors. The robustness of these light grids continues with the precipitation filter which makes it possible to deploy the SG10 in outdoor applications where it is exposed to rain, snow and fog. The filter ensures that the signal unintentionally is triggered because of the weather conditions and reliable detection is thus guaranteed. Because of all these advantages the SG10 is suited for use in many access systems such as gates, fences, car lifts and barriers.

Think for example of stacked wooden plates or metal beams on a pallet which are transported on a conveyor. A singl misplaced beam or plate can cause delay in the entire production process. The light grid timely measures and detects the protruding and misplaced part of the pile. This way downtime can be reduced or entirely prevented.

The SG11 are the most familiar light grids from Telco Sensors. The SG11 is in the elevator industry a known term because of the controller and a set of light grids that are provided with stereo plugs. They distinguish themselves from the SG2 due to the smaller beam spacing so the detection is more accurate. Furthermore the SG11 has a broad range of 4 meter. This light grid is fully utilized when it is equipped with the SGC amplifier. The amplifier offers many possibilities of which an automatic setting for the sensitivity. This setting makes sure that the light grids have the optimal sensitivity on the basis of for example environmental factors such as the presence of dirt in an application such as person detection at the roller door of a hall where animal food is stored. The accumulation of dust particles can attenuate the signal so that this has to be asjusted. That is where this function comes into its own.

The setting can be served manually with a potentiometer. For the broad deployment in different applications, the light grid has different outputs. Together with the outputs there is also a time-out functions that is important for muting the detection of objects which are permanently present in the field of view of the light grid. Think for example the skate in an elevator door.

For preventive maintenance, the light grid is provided with an internal recognition of mistakes such as cable fractures, electrical disruptions and false operation of the emitter and receiver. In case of any of these mistakes these are showed with an indicator. Here, the problems are fixed on time and costs are saved in time and money.

The SpaceGuard SG15 is a special light grid that is provided with a TÜV-certification. This means that it can be used as a safety system on its own. Other access systems such as an underflow profile should first hit a person, vehicle or object before the door comes to a stop. The SG15 stops the door with a detection, before the door has made contact with the person, the vehicle or the object.

It is also possible with the SG15 to choose between multiple outputs, such as an OSE-output or a relais. The OSE-output is, as mentioned before, an output that especially functions as safety output for light grids. This output carries out a test automatically before the door closes.

Since this light grid is meant for use on the industrial doors and this grid is available in a height of 1.93 m, 2.29 m and 2.65 m. Doors higher than 2.5 m thus only need to be actively secured up to the height of 2.5 m. Therefore the light grid of 2.5 m. is ideal for securing a door of this scope.

The SGP 30 light grids is provided with a mounting rail and can be used without reflector or receiver. This is because the SGO 30 is housed as a diffuse proximity light grids that detects objects via the received reflection. Due to the different available types of housings and a control-input the SGP 30 is very versatile.

A diffuse proximity especially excels in applications with a limited space such as in a sawing,- sanding,- or packaging machine. An example of an application is the detection of boxes on a conveyor which transports these to packaging machine.

The SS02 series is a very advanced light grid that supports a wide scale of geometric analyse functions, which can be used for measuring-, positioning- and surveillance functions. Think here about the detection of boreholes in metal sheets in the metal industry or about the horizontal and/or vertical measurement of boxes on a conveyor in the packaging industry which can be in the image. Also in the textile industry these light grids help with the edge guiding of fabrics which are added by a textile feeder.

The light grids can be configured in such a way via the PC that they fit perfectly within the desired application. On the PC it is also possible to read out the measured values in real-time. Furthermore the SS02 offers the possibility to use analog outputs as well as digital switching outputs. After setting up there is also the possibility to control the configuration with a test-input. To be certain that all works well in an application there is also a synchronization-function which calibrated the emitter and receiver. This way, the SS02 can be excellently adapted to the application!
