Draw-wire mechanisms for encoders are not a specific brand but a category of industrial measurement devices used in various applications. These mechanisms, also known as string potentiometers or cable extension transducers, are produced by several companies worldwide. Notable manufacturers include Germany's ASM GmbH, which specializes in high-precision draw-wire sensors, and the US-based SpaceAge Control, known for rugged linear position sensors. These devices serve industries like automation, robotics, construction, and material handling. Key products include linear displacement sensors, encoder interfaces, and compact draw-wire systems for measuring linear motion. The technology is widely available through industrial suppliers like Radwell and Grainger.
