In the world of industrial automation, providing exceptional performance in a highly compact package can be an enormous advantage. So encoder manufacturer POSITAL has unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22 mm and a height of 23 mm (0.87 in.) […]
IXARC absolute encoders with IO-Link interface from POSITAL
POSITAL has announced that its family of absolute IXARC rotary encoders has been expanded to include support for the popular IO-Link communications interface. IO-Link is a low-cost, easy-to-implement communications system designed to simplify connections between large-scale fieldbus or industrial Ethernet networks and sensor or actuator devices located on the factory floor. On one side of […]
POSITAL-FRABA multi-turn hollow shaft kit encoders — Rockwell Encompass Complementary Products
POSTIAL-FRABA’s new hollow-shaft kit encoders are now a complementary product in Rockwell Automation’s PartnerNetwork Encompass program. These new products mark a significant innovation for industrial motion control. Until now, almost all through or hollow-shaft encoders have been limited to a single-turn measurement range, largely because fully satisfactory multi-turn technology has been not been available. POSITAL […]
What happens when a multi-turn encoder reaches 4096 turns?
One of the first decisions when choosing a rotary encoder is whether it should provide incremental or absolute position feedback. That choice primarily depends on whether the encoder should be able to exactly detect its position upon startup. If so, then an absolute encoder is typically required. When considering an absolute encoder, the next decision […]
Absolute encoders from Encoder Products Co. now with PROFINET
The Model A58HE and Model A58SE Ethernet-ready, multi-turn absolute encoders from Encoder Products Company (EPC) are designed for harsh factory and plant environments. In addition to EtherCAT Deterministic Communication, the two models now feature the PROFINET communication protocol as well. These encoders are particularly suited to applications where fieldbus connectivity is required, and the encoder […]
POSITAL kit encoders for cost-effective position control of stepper motors
While servomotors remain the gold standard for precision motion control in industrial machinery, the improved performance of stepper motors is making these lower-cost devices an increasingly attractive alternative for many applications. The key to these performance gains is the addition of rotation-measuring encoders, especially the new absolute multi-turn kit encoders from POSITAL. Stepper motors are […]
Encoder Products absolute encoders – now with improved electronics
EPC’s line of absolute encoders offers magnetic multi-turn technology and higher resolution. Encoder Products Company (EPC) offers a full line of absolute encoders with models in both shaft and blind hollow bore, in sizes 36 mm, 58 mm, and standard size 25 with a 2.5 inch housing. Now, EPC absolute encoders come with even more […]
What features make resolvers suitable for harsh environments?
Resolvers were initially developed for military applications and are probably best known as the preferred feedback solution in harsh environments. Where optical or magnetic encoders are sensitive to dust, liquids, and magnetic fields, resolvers can operate in dirty, humid, wet, and high-radiation environments. But what is it that makes them so robust under conditions that […]
POSITAL adds to its range of kit encoders
POSITAL is expanding its line of kit encoder solutions for motion control applications to satisfy a wider range of needs faced by machine builders, system integrators, and motor manufacturers. Kit encoders are component-level products, designed to be built into motors or other types of equipment where real-time measurement of rotary position (angular displacement) or rotational […]
What is an LVDT (linear variable differential transformer)?
A linear variable differential transformer (LVDT) is an absolute measuring device that converts linear displacement into an electrical signal through the principle of mutual induction. Its design and operation are relatively simple, providing extremely high resolution in a device suitable for a wide range of applications and environments. The main components of an LVDT are […]
