SICK SEM90 Series Absolute Absolute Encoder, 64ppr ppr, Binary Signal, Through Hollow Type, 50mm Shaft

The trend toward compact and rugged direct drives in factory automation has clearly strengthened in recent years. With the SES/SEM 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 multitier 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.
