A new flameproof and explosion-proof encoder that meets UL, ATEX, and IECEx standards — Model LP35 from BEI Sensors — is the first hollow-shaft encoder with a 2.01-in. profile that operates directly in Division 1, Zone 1 environments. It’s for oil and gas machinery that must withstand extreme conditions where ignitable concentrations of flammable substances can exist under normal conditions. “In […]

Top encoder trends for 2015: Smarter, more reliable designs
As critical components in motion control systems, encoders have come a long way from the mostly mechanical devices of yesteryear. We asked some leading encoder manufacturers to tell us how encoder designs are changing and what industries and applications are driving those changes. Here’s what those manufacturers said. 1. What are some of the key […]
Magnetic ring encoder benefits large rotating machinery
The Leine & Linde MRI 2000 rotary encoder is designed to provide feedback solutions for large rotating machinery, typically found in the Construction, Pulp & Paper, Oil & Gas, Wind and Marine industries. Introduced two years ago, this encoder has now received significant performance upgrades. The MRI ring encoder is segmented into pieces, something that […]
Bringing on-line vibration measurement to wind turbine generators
Planning maintenance activities on wind turbine generators, rather than dealing with emergencies, can result in significant reductions in operating expenses. To assist in that process, Leine and Linde offers rotary encoders equipped with a web-based Advanced Diagnostic System (ADS) providing real-time tracking of the generator condition. Especially well suited for use in wind turbine generators, […]
IXARC rotary encoders with EtherCAT interface
POSITAL’s high-performance IXARC optical rotary encoders are now available with EtherCAT communications interfaces. EtherCAT (Ethernet for Control Automation Technology) is a special form of industrial Ethernet that eliminates the unpredictable transmission delays that characterize ‘standard’ Ethernet networks. EtherCAT networks ensure very rapid communications between a controller and other devices within a control system so that […]
New Stainless Steel Model 600 Encoder for Severe Environments
Leine & Linde introduces a new stainless steel version of the well known ISA and IHA 600 series of absolute rotary encoders. Designed to provide motion control and feedback for machines in harsh environments, the IXA 600 stainless steel model is useful in applications where the encoder is subjected to saltwater, acids, or other aggressive […]
Netzers New DS-25 Lightweight Miniature Absolute Rotary Encoder
Rotary Electric Encoders™ from Netzer provide exceptionally accurate, high resolution, absolute position with miniature to wide diameter hollow shaft and are available with analog or digital outputs. The holistic structure of the Electric Encoder™ provides generous mounting tolerance, thus obviating the need for internal ball bearings. The lack of bearings and components such as flexible […]
New Absolute Rotary Encoders with Functional Safety
As the demand for functionally safe equipment products grows, so does HEIDENHAINs component product offerings. Now new to the market are HEIDENHAINs ROx 400 absolute rotary encoders, available in a functionally safe design including a mechanical fault exclusion for the shaft. Both the synchro and clamping flange versions passed the type testing from TÜV Süd, […]
US Digital Awarded ISO 9001:2008 Certification
US Digital, a U.S. manufacturer of optical rotary encoders, announced they have achieved the ISO 9001:2008 certification. Scope of Registration includes design, manufacturing, assembly and distribution of motion control products and accessories. US Digital received the certification from PRI Registrar, which involved a rigorous audit of business processes, manufacturing processes and products. As part of […]
How to select, apply and integrate the right encoder for an industrial automation application
Updated June 2016 by Lisa Eitel || by Joe Kimbrell, Product manager, Drives, Motors and Motion, AutomationDirect Encoders are used to determine the position, velocity and direction of motor shaft speed and other mechanical motion. They provide information required for the precise control of a variety of applications, such as positioning a rotary table, pick […]
