Description

The position range monitors

The electronic position switches ERC 40 make it possible to flexibly monitor position ranges. For example, they are deployed in hoisting gear, in crane technology and in mining operations as well as in screw downs and side guides in steel works. The electronic position switches are often used as a simple 1:1 replacement solution in legacy systems where mechanical rotary cam limit switches are installed; moreover, they can also be integrated in new systems without any difficulty. They ensure high accuracy and facilitate fast and easy system calibration by means of presets, by setting switching points as well as uncomplicated data storage.
