Touchless linear position sensors for tight spaces
The new TFD Series of touchless linear position sensors from Novotechnik, U.S. provide wear-free operation in tight spaces, with maximum sensor dimensions of 40 x 27 x 7 mm thin. Sensing direction can be either parallel or perpendicular to mounting holes. The TFD-4000 Series uses a magnetic position marker to provide a touchless measurement range […]
Magnetic linear encoder from SIKO offers absolute position and speed data
The MSA213K high-resolution, non-contact absolute linear encoder from SIKO provides the absolute position at any time, without referencing or buffer battery. With its high signal quality, the encoder is ideal for use in handling and assembly automation, machining systems, pick-and-place applications, PCB machining and always provides precise values for position and speed measurement in linear […]
Choosing linear and angle encoders for semiconductor machinery
The manufacture and testing of semiconductors involves the competing requirements of nanometer positioning and high throughput. Here, the right encoder can help motion designs deliver on both counts. By HEIDENHAIN CORPORATION staff engineers Semiconductor manufacturing and testing equipment can have the best motion-control bandwidth, artificial intelligence capabilities, and optics in the world, but none of […]
Renishaw’s on-machine tool measurement features expanded range, improved repeatability
Building on the success of the original NC4+ Blue, the latest evolution of the non-contact tool setter features an ultra-compact design and is now available in four sizes, with operating gaps ranging from 55 to 240 mm. Measurement repeatability has also been improved across the range, now down to +/- 0.5 micron on smaller separations. […]
Magnetostrictive linear position transducers from AutomationDirect
AutomationDirect has added Gefran WPG and WPP series magnetostrictive linear position transducers. These transducers work like other linear position sensors by translating a linear position to an electrical signal. However, they are contactless, which provides a longer life because there is no mechanical wear. Because they use magnetostrictive technology, they’re also immune to electromagnetic interferences. […]
Kit-style linear encoders for high accuracy positioning
The new LIKselect kit-style linear encoder is designed to make machine motion design ideas come to life while saving valuable space and enabling precise positioning within its control loop. Available now from NUMERIK JENA in North America as part of the HEIDENHAIN group, this miniature three-field scanning sensor is offered with a variety of different […]
Magnetostrictive linear position sensor provides absolute position
The updated Gemco 956 eBlok linear position sensor from AMETEK Factory Automation is a Rod & Barrell style package that can help simplify installation and serviceability and improve on performance and price without affecting quality. The Gemco 956 eBlok is a high-performance, cost-effective linear position sensor designed for applications that often would choose traditional linear […]
New sealed linear encoders for metrology applications
RSF Elektronik’s newly designed sealed linear encoder series are suitable for high-end metrology applications. Offered through parent company HEIDENHAIN CORPORATION in North America, these MSA 7xx/8xx model encoders offer high quality and easy mounting that are well suited for use on CMMs, optical comparators, video measuring machines, among other types of measuring equipment. The MSA […]
How is an LVDT similar to a resolver?
Both LVDTs (linear variable differential transformers) and resolvers are measuring devices that convert displacement into an electrical signal. As its name implies, an LVDT is used for linear measurement, while a resolver is used to measure rotary, or angular, displacement. In terms of construction and operation, the most significant similarity between an LVDT and a […]
