The ELS35-0CA0A024A-40 is a compact, high-resolution singleturn motor feedback encoder developed by SICK. It uses the BiSS C digital interface, allowing both power and data transmission through a single cable, reducing wiring complexity and simplifying installation. It is specially designed for motors with a 35 mm diameter, making it ideal for space-constrained applications.
