Features

LIMAX was developed as a global platform solution for elevator manufactures and represents with its position characteristics an economical, insensitive and installation-friendly alternative to conventional elevator positioning. With its maximum measuring distance of 1000 meters LIMAX covers all possible measuring heights for elevators worldwide at this time. No gauging or reference runs after start-up is necessary. The unit and follow up electronic is mounted directly on the elevator cabin (e.g. roof of the cabin). Additional features, e.g. redundancies (according to the elevator guideline EN-81) and a floor recognition system, are available as options. The standard system is equipped with a magnetic tape guidance and is further available with helpful mechanical accessories to provide a simpler and user-friendly installation. The magnetic tape guidance insures for the correct distance from the sensors to the magnetic tape and consists of a special self-lubricating plastic. Three integrated guideways in the sensor housing permit a simple assembly (possible from 3 sides). The flexible magnetic tape can be hung vertically, spring loaded or mounted with a weight on the bottom of the elevator shaft. Available output interfaces can be CANopen (standard), RS-422, RS-232 and SSI. The sensor housing is IP 50 protected in standard version. Further IP 67 is possible as Option V (sealed version).
