POSITAL’s new series of measuring wheel accessories for its IXARC family of rotary encoders turns them into linear position sensors. When one of the wheels is mounted on the shaft of an encoder, the result is an accurate and reliable instrument for measuring linear motion and position. The new measuring wheels are available in circumferences […]

Linear motor stage with absolute encoder and ironless motor
Physik Instrumente has released a new member of the PIMag family of precision positioning stages with magnetic direct drives. The compact ultra-precise V-551 motorized linear translation stage debuted at Laser World of Photonics, held in Munich, Germany last month. V-551 comes equipped with an integrated absolute-measuring, 2nm resolution encoder – no more wasted time for […]
Tiny kit-style encoder: New option for linear measurement
A tiny linear encoder from RSF Elektronik is an MS 15 optical kit-style with the smallest mechanical profile in the industry. Available in North America through HEIDENHAIN, the encoder works in machinery for metrology, semiconductor, medical and automation. The MS 15 optical kit-style encoder is 36 x 13.5 x 14.8mm in size, and provides a 40 […]
Linear Cable Transducer from BEI Industrial Encoders
BEI Industrial Encoders’ new linear cable transducer provides digital position and speed feedback information in a rugged, easy-to-install package. Model LT25 cable transducer utilizes a flexible measuring cable mounted to an internal spring-loaded spool and a quadrature encoder output to precisely measure linear motion applications. The sturdy cable is made of nylon coated stainless steel […]
SIKO expands encoder offerings with industrial Ethernet versions
SIKO GmbH is expanding its broad portfolio of encoders with new Industrial Ethernet versions. The new encoders offer answers to the requirements of complex machinery and Industry 4.0. The optical based WV5850 and WH5850, in either single or multi-turn versions, offer high resolution and quick response in applications requiring extreme precision and fast response times. […]
What are interferometric laser encoders and where are they used?
Optical encoders such as glass scales are often used for linear position measurements that require micron-level resolution. But applications in industries such as semiconductor and aerospace — especially those that involve optics — require measuring capabilities in the nanometer and even picometer ranges, beyond the resolution of most scale-based optical encoders. For these applications, direct, non-contact […]
What type of encoder can measure speed?
Encoders and resolvers are used to track the angular or linear position of an object, such as a motor shaft (angular measurement) or a linear actuator (linear measurement). And with the addition of a clock signal, encoders and resolvers can also be used to measure the speed of the object. A resolver uses a rotor with […]
What’s the difference between radial and axial ring encoders?
A traditional rotary encoder measures the position or speed of a rotating shaft, with mounting via a coupling or a hollow bore that allows the encoder to fit over the shaft. But not all rotating components have a shaft to which the encoder can mount. For example, direct-drive rotary motors — also known as torque motors, […]
Shaft absolute encoder designed for harsh environments
The new Model A58SB absolute bus encoder from Encoder Products Company (EPC) is designed for harsh factory and plant floor environments. Heavy duty, rugged and reliable, this shaft absolute encoder is available in both single and multi-turn resolution. As an absolute encoder, it’s especially suited to applications where an encoder needs to retain position information […]
What are inductive encoders and how do they differ from resolvers and LVDTs?
Position measuring devices that rely on the principle of mutual induction include resolvers, linear variable differential transformers (LVDTs), and inductive encoders. Two of these technologies — resolvers and LVDTs — are based on the construction and operation of a transformer. In the case of an LVDT, voltage is applied to a primary winding and induced in […]
