The EDM35-2KF0A020A is a compact, high-resolution multiturn encoder developed by SICK, intended for use in motor feedback systems. It uses the HIPERFACE DSL® digital interface, which combines power and communication into a single cable, reducing installation complexity. With its 35 mm housing diameter, it's perfect for applications where space is limited.
