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.
