| Technical description |
|---|
| The absolute linear-transmitter is constructed
for guided rail-installations, which is supplied through a contact-line and where the position is
to be locateg by the controlling unit at every time.
According to the principal the position of LAP is to be located slip-free and absolutely. Genrally the use is also possible outside of the contact-lines, if the applictaion is guaranting the keeping of the technical datas. |
|
| Advantages: | in case of power failure there is no need to steer to a reference.
Even if the electric drive was moved during a power failure, LAP is ready to locate the latest position
right after starting.
As the position is without slip, it is possible to adjust tight to the actuality. The buffer-action of the vehicle is individual to handle according to the systems's environment. |

LAP consists of a magnet tape, wich typifies the measure, as well as a read head with integral logic, that transmitts the position over th einterface to the control unit. The linear-transmitter rail integrated parallel to the slide rail or space saving in the LASTRO-contact-conductor rail system.
The intelligent read head gathers the position out of the linear-transmitter rail and analyses them ready to handle for downstreamed controls.
The link to the control is realised with a round plug connection with the screw coupling IP 67/68, 4-strand.
