Specially developed absolute (Looper) encoder for most extreme environmental conditions

With the Looper encoder ALS 40 K Johannes Hübner Giessen has introduced the next worldwide encoder to the market.
With its ALS 40 K Johannes Hübner Giessen has developed a special loop encoder, which offers a significantly longer service life. It boasts specially dimensioned bearings with a 40% higher dynamic rating and a special radial shaft sealing ring with an additional protective lip. The new encoder delivers a guaranteed high quality signal and high levels of availability while operating under the typically high temperature and shock loads to which loopers are subject.
