Feedback options for linear motors and direct-drive torque motors abound. The most common employ optical, magnetic, capacitive, or inductive measurement. Here we explain how the key application parameters of precision, cost restrictions, and insensitivity to mechanical characteristics and environment dictate which technology is most suitable.

Encoders + sensors (linear) + I/O
Space-saving integrated guide, linear encoder from THK
The new Type SHS-LE from THK integrates the global standard THK Type SHS LM guide with a THK linear encoder (linear position sensor). This combined model allows for compact machine designs that require less assembly time. THK’s Type SHS Caged Ball LM Guide performs with high speed and precision. Each row of balls is arranged […]
Balluff offers intelligent position measuring system for absolute linear feedback
The BMP series from Balluff is an intelligent displacement sensor that provides not only the absolute position signal for the stroke travel of a piston via IO-Link but also information about the sensor status and the current ambient conditions. It monitors the sensor temperature and the number of starts and issues warnings when a configurable […]
How to calculate maximum encoder speed for linear and rotary designs
When choosing an encoder for motion applications, a few specifications immediately come to mind. What sensing technology should you use? What accuracy and resolution do you need? Does the application require incremental or absolute position feedback? But one specification that is sometimes overlooked during sizing and selection is the maximum encoder speed. Like any electrical […]

SIKO’s new SG61 draw-wire linear sensor measures lengths to 6 m
SIKO — maker of wire-based sensors — now sells SG61 wire-actuated encoders. These are suitable for measuring lengths up to 6 m. On the basis of 30 years of experience in development and production, a wire-actuated sensor has been designed that impresses with its compactness, sturdiness and flexibility. Compact and robust wire-based linear sensor The […]
What are draw-wire sensors and where are they used?
Options abound for tracking or measuring the position of a linear system — from magnetic and optical linear encoders that read changes in magnetism or light, to linear variable differential transformers that operate on the principle of mutual induction, to magnetostrictive sensors that rely on torsional strain induced by magnetic fields. But each of these technologies requires […]
