The EDM35-0KF0A020A is a compact, high-resolution multiturn encoder developed by SICK for motor feedback applications. It uses the HIPERFACE DSL® interface, which combines power and data in a single cable, simplifying installation and reducing wiring complexity. With a 35 mm housing diameter, this encoder is ideal for integration into small motors and tight spaces.
