Wire Draw Mechanism – HighLine, 0–2 m Measuring Range, Servo Flange (6 mm Shaft) – MRA-F080-102D2
Product Overview

The SICK MRA-F080-102D2 is a precision wire draw mechanism designed for use with wire draw encoders. Offering a measuring range of 0–2 meters, this mechanism ensures highly reliable and repeatable linear position measurements in industrial applications. Built with robust stainless steel cable and durable housing materials, it is ideal for demanding environments where accuracy, speed, and long service life are essential.

This HighLine model is engineered for integration with encoders via a servo flange (6 mm shaft), enabling seamless conversion of linear motion into precise rotary encoder signals.
