Absolute Encoders

Absolute encoders from Encoder Products Co. now with PROFINET

September 19, 2019 By Miles Budimir Leave a Comment

encoders

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

June 29, 2019 By Lisa Eitel Leave a Comment

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 […]

What features make resolvers suitable for harsh environments?

March 29, 2019 By Danielle Collins Leave a Comment

resolvers

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 […]

What is an LVDT (linear variable differential transformer)?

November 3, 2018 By Danielle Collins Leave a Comment

LVDT

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 […]

Heavy-duty absolute encoders — now with EtherCAT communications

October 2, 2018 By Lisa Eitel Leave a Comment

New EPC Model A58HE and Model A58SE are EtherCAT-ready, multi-turn absolute encoders for harsh factory and plant environments. They work in applications where fieldbus connectivity is required, and the encoder must retain absolute position information after power-off events. The Model A58HE is a 58-mm encoder in a hollow-bore construction, and the Model A58SE is a […]

POSITAL closed-loop motor feedback for absolute positioning

July 2, 2018 By Lisa Eitel Leave a Comment

POSITAL FRABA encoders for closed-loop motor feedback allow upgrades to existing motion control applications. The mechanical drop-in replacement encoders have the same footprints as US Digital’s E5 models and Broadcom’s (Avago) HEDS-5500 models. POSITAL kit encoders provide absolute position feedback — to give controls complete information on the physical position of the mechanical components they’re […]
