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 […]
NUMERIK JENA’s new LIKgo linear encoder for semiconductor industry
NUMERIK JENA’s newly designed LIKgo is a low-cost linear encoder that meets the demands for use in production and inspection machines in the semiconductor industry. Available in North America through HEIDENHAIN CORPORATION, the LIKgo encoder will be showcased at its SEMICON booth #851 during this July 9-11 show in San Francisco. The new LIKgo is […]
New induSENSOR controller for inductive displacement sensors
The new induSENSOR MSC7401 controller from Micro-Epsilon works for displacement and distance measurements in automation technologies and machine building. The controller is compatible with inductive LVDT and LDR measuring gauges and displacement sensors from Micro-Epsilon. The MSC7401 controller is designed to be operated with LVDT and LDR measuring gauges and displacement sensors. These sensors are […]
Micro-Epsilon draw-wire sensor is smallest in the world
The new Micro-Epsilon wireSENSOR MT19 draw-wire sensor has a weight of only 8 g and a size of just 19 x 19 mm. This wireSENSOR MT19 linear sensor is used for displacement and distance measurements with a measuring range of 40 mm. The dynamic sensor is compact and enables wire accelerations up to 60 g. […]
High-resolution absolute encoder from SIKO
The new MSA213C high-resolution absolute sensor from SIKO satisfies the requirements for sensors used for position detection in automation and drive technology. It supplies the absolute position at any time without referencing and without requiring a backup battery. Plus, with its small design and many different interfaces, it can be integrated into the system and […]
Renishaw’s new easy-to-install incremental encoder
Renishaw has launched a new encoder family for linear axes, which offers exceptionally wide installation tolerances and axis speeds of up to 24 meters per second. The QUANTiC encoder series produces a digital signal output directly from the readhead and eliminates the requirement for additional bulky external interfaces. This ground-breaking approach was first used for […]
What is Abbé error and how does it affect linear systems?
When evaluating the accuracy of a linear motion system, the area of focus is often the positioning accuracy and repeatability of the drive mechanism. But there are many factors that contribute to the accuracy (or inaccuracy) of a linear system, including linear errors, angular errors, and Abbé errors. Of these three types, Abbé errors are probably […]
