Singleturn looper encoder

Loop lifter or looper encoders are subjected to demands that shorten their service life considerably. The looper encoder from Johannes Huebner Giessen AL… 40 is especially designed and built for this field of application, a fact that enables it to provide service lives many times greater than is usually the case. Filled with a special grease, the bearings have a 40 percent higher dynamic load rating and are suitable for shock loads up to 450 g. A special radial shaft seal and additional sealing lip provides the required level of protection in harsh environments. It is possible to configure the looper encoder AL… 40 via an SSI or parallel interface.
