Singleturn absolute encoders for rough conditions
Looper encoders AL…40 are absolute encoders designed for the most extreme conditions with shock loads up to 450 g. They are mostly deployed in roll stands in hot rolling mills between the roll housings where they subject to high levels of energy. They supply precise information about the angle position of the looper, which is used for the highly dynamic feedback speed control of the rollers. At the same time the AL…40 reach a service life many times longer than other models. Lubricated with special grease their ball bearings offer an approximately 40 per cent higher load rating.
