We offer standard linear position sensors but can also help you with a customized design or a complete measurement solution.

Draw-wire sensors, also known as string potentiometers or cable extension transducers, are versatile devices used for linear position measurement. We offer a range draw-wire sensors, designed to deliver precise and reliable measurements in diverse applications.They consist of a wire wound around a spool, connected to a moving object whose position needs to be monitored. As the object moves, it pulls or releases the wire, causing the spool to rotate. This rotation is then converted into an electrical signal, providing real-time feedback on the object's position.

High accuracy

Draw-wire sensors offer exceptional accuracy, ensuring precise measurements even in demanding environments. This makes them ideal for applications where precision is critical, such as robotics, automation, and aerospace.
Long measurement range

With their extended measurement range, draw-wire sensors can monitor the movement of objects over considerable distances. Whether it's a few millimeters or several meters, these sensors provide reliable data across a wide range of motion.
Compact and lightweight design

Designed for ease of installation and integration, draw-wire sensors feature a compact and lightweight construction. This makes them suitable for space-constrained applications without compromising on performance.

The draw-wire sensors are able to withstand harsh operating conditions, draw-wire sensors are highly durable and resistant to mechanical wear and tear. This ensures long-term reliability and minimal maintenance requirements, contributing to cost savings and operational efficiency. Whether it's vertical, horizontal, or angled installation, draw-wire sensors offer versatile mounting options to suit different applications and configurations. This flexibility enhances their adaptability across various industries and environments.
