Incremental encoders typically use two square-wave signals in quadrature (out of phase by 90 degrees) to track position and direction of motion. But because they only track incremental position (not absolute position) they’re not able to determine the true position of the motor and connected equipment after a shut-down or power loss. So most incremental […]
Rotary Encoders
Encoders with Siemens DRIVE-CLiQ interface for small-motor manufacturers
In order to meet the needs of manufacturers of small servo motors and actuators, HEIDENHAIN introduces an expansion of its small-diameter 1000 and 1100 series rotary encoders with added versions now available with Siemens DRIVE-CLiQ. HEIDENHAIN’s models ECN/EQN 1000S, ROC/ROQ 1000S and ECN/EQN 1100S rotary encoders with integrated DRIVE-CLiQ interface feature a compact design with […]
Networked rotary encoders from Advanced Micro Controls boast new features
Advanced Micro Controls Inc. has added new features to their NR60E2 series of networked absolute rotary encoders. The new features include a Profinet interface, E2 Technology, Hub Shaft (Blind Shaft) Option, and Stainless Steel units. These rotary sensors provide an overall measuring range of 16 bits (single-turn resolution) plus 14 bits (number of revolutions), for […]
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 […]
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 […]
Large through-hole angle encoders from HEIDENHAIN offer high accuracy
HEIDENHAIN’s new sealed angle encoders can be used as an alternative to modular angular encoders in motion control machining applications that require a larger than usual through-hole. The new RCN 6000 series absolute sealed angle encoders with integral bearings have an exceptionally large hollow shaft diameter of 180 mm (7.09 in.), allowing larger scale machines […]
Posital upgrades family of analog programmable rotary encoders
Encoder specialist Posital has announced a new generation of analog rotary encoders for position control. Compared to the company’s earlier analog encoders, these new models feature improved accuracy, faster dynamic response and new programming options. They also accept a wider range of supply voltages, an advantage for mobile machinery applications. Posital’s analog encoders are designed for […]
Totally encapsulated J1 rotary encoders IP69k electrical protection from Joral
Joral LLC now has a new method to impart total encapsulation in its J1 electronic components. Specially crafted to ensure total protection from extreme temperature fluctuation, intense machine vibration, and pressure wash down, the Joral J1 line-shafted rotary encoders perform rotary motion feedback for industry, ranging from directional drilling rigs to timber harvesters. The new […]
Joral introduces true non-contact rotary encoder with rectangular design
PE18 ProxEncoder non-contact rotary encoder product line receives a square housing with side sense capacity. Enhancing the original PE18 proximity style form factor, the new rectangular design allows for easy mounting on flat surfaces. Two USPTO patents enable the PE18-BX ProxEncoder to detect on-axis rotation with up to 0.5-in. (12mm) air gap between the application and […]
