The trend toward compact and rugged direct drives in factory automation has clearly strengthened in recent years. With the SES/SEM70 rotative motor feedback system with industrial HIPERFACE^® standard interface, SICK is providing new options for hollow shaft types and direct drives. The motor feedback system, which works with holistic sensing, is mounted directly on the drive shaft without addition mounting tools and renders transmission components such as timing belts or couplings unnecessary. A mechanical multiturn function is also integrated into the device, which eliminates the need for additional components such as external buffer batteries. The small design saves space and weight and is rugged, wear-free and reliable thanks to the bearing-free technology.
