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 […]
HEIDENHAIN’s new LC 201 single-section linear encoder for absolute applications
Long machine tool axes are increasingly being equipped with linear drives, and HEIDENHAIN’s new LC 201 absolute linear scale was introduced to specifically meet those drive position feedback needs. This new scale is a single-section METALLUR tape encoder that’s ideal for use in linear motor applications that may be required to reach high acceleration levels […]
Where are glass scale linear encoders used?
Linear encoders are generally classified by their scanning technology — optical or magnetic. Magnetic encoders use a metal scale (often referred to as a “tape”), while optical encoders use a scale made of either metal or glass. Although magnetic encoders have seen great improvements in resolution and accuracy in recent years, for single-micron and sub-micron […]
What is sub-divisional error (SDE) in linear encoders?
To determine the position of a linear axis, an encoder read head travels along a scale and “reads” changes in light (for optical encoders) or magnetic field (for magnetic types). As the read head registers these changes, it produces sine and cosine signals that are shifted 90 degrees from each other (referred to as “quadrature […]
Magnetic linear encoder solves issues with variable gap distance
New Balluff product delivers impressive 12 micrometer accuracy at 1.0 mm A new magnetic incremental linear encoder system with exceptional ride height provides a much needed solution for applications with variable gap distance. The new BML SF2 system from Balluff provides 12 micrometer system accuracy at gap distances up to 1.0 mm and a maximum […]
