Lineshaft Pacer Encoders
The ability to interface a position encoder to a ServoWire Drive can provide vital position information to the motion control system.
This approach is simple, yet effective, because information for the "encoder axis" is available to be used in the same way that information is used from any "servo axis".
Key Features
* Heavy Duty sealed bearings and NEMA 4X housing
* Flange Mount with integral coupling and servo mount configurations available
* 200 KHz Frequency response for all channels
* Optional 2X, 4X, 5X or 10X cycle interpolation
* Maximum Data Rate increases to match cycle interpolation
* LED light source

Angle Encoders without Integral Bearing
The HEIDENHAIN ERP, ERA and ERO angle encoders without integral bearing are intended for integration in machine elements or components. They operate without friction and permit high accuracy. This makes them particularly attractive for high-precision angle measuring tables and precision devices in angular metrology. The attainable system accuracy depends on the eccentricity of the graduation to the drive shaft bearing, as well as the radial runout and wobble of the bearing.

ASM introduces new POSIROT® Magnetic 360° Angle Sensor
ASM GmbH has expanded its innovative line of POSIROT® angular position sensors with the introduction of a new magnetic angle sensor in a 20 mm (0.8 in.) flat, 36 mm (1.4 in.) diameter servo flange housing. PRAS2 is a dependable, contact-free and wear-free sensor that utilizes an external permanent magnet to measure complete angular position from 0° to 360° with a typical resolution of 0.1°.
PRAS2 models are available with three different analog outputs: 4-20 mA, 0.5-4.5 V and 0.5-10V. The angle measurement circuitry is shielded from external environment conditions. It has also been designed to be highly shock- and vibration-resistant.
With its low 20 mm (0.8 in.) height, this new compact model, PRAS2, can be quickly installed without requiring much space.
Since this sensor is in a rugged IP 68 stainless steel housing, it can reliably handle the toughest industrial environments and makes it suitable for many applications such steering and tilt angle measurement on mobile construction equipment.

The new 424Dxxx Angle Sensor from elobau features high precision paired with extraordinary robustness.
Depending on the model, it can execute angle measurements ranging from 20° up to a complete circle ranging from 0° to 359°.
The non-contact design provides exceptional reliability. The measurements are made with a magnetic field whose rotation is detected with a non-contact Hall sensor. Another benefit of this construction principle: the sensor does not require a limit stop. Thanks to its IP 67protection class, the sensor is protected against all effects of dust and water which may be present in industrial processes and in vehicles. Other features are short-circuit protection, electromagnetic compatibility as per DIN 40389 for automotive applications as well as high-quality and durable ball bearings for the rotating axis. Operating temperatures range from -25°C to +85°C (-13°F to +185°F).
The unit’s resolution of 0.1 degrees with a signal refresh rate of 300 Hz is evidence of it high accuracy. The angle sensor also features a highly homogeneous signal curve with a maximum linearity error of ± 1 percent. The analog output optionally ranges from 1 to 5 V, 4 to 20 mA or 0.5 to 4.5 V. With these features, the 424Dxxx Angle Sensor can be used for almost any mechanical or automotive engineering application.

AC operated Rotary Variable Differential Transformers (RVDTs) measure rotary position up to +/-60degs. Like AC LVDT’s they contain no signal conditioning and are therefore chosen for their smaller size and use in hostile environments.
Description: RVDTs incorporate a proprietary non-contact design that dramatically improves long term reliability when compared to other traditional rotary devices such as syncros, resolvers and potentiometers. This unique design eliminates assemblies that degrade over time, such as slip rings, rotor windings, contact brushes and wipers, without sacrificing accuracy. High reliability and performance are achieved through the use of a specially shaped rotor and wound coil that together simulates the linear displacement of a Linear Variable Differential Transformer (LVDT). Rotational movement of the rotor shaft results in a linear change in the output signal, directly proportional to change in shaft angle, over ±60 degrees from the null position. The phase of this output signal indicates the direction of displacement from the null point. Non-contact electromagnetic coupling of the rotor provides infinite resolution, thus enabling absolute measurements to a fraction of a degree. The R30A and R36AS RVDTs are AC operated rotary transducers. AC excitation of 3 V rms results in a ratiometric AC output voltage that varies in direct proportion to the change in angular position of the transducer shaft.

No One Protects Large Turbines like GE
The transducers in this category measure changes in machine case positions as they expand or contract, rotary or linear position of control valves, or wicket gate position on hydroelectric turbines. They are typically used in conjunction with other transducers as part of a Turbine Supervisory Instrumentation (TSI) package, designed to monitor all critical machinery parameters on large steam, gas, or hydraulic turbines used in power generation applications.
The 3300 XL Rotary Position Transducer (RPT)
This innovative transducer incorporates a proximity probe observing an eccentric cam. The changing gap between probe tip and cam corresponds to degrees of rotation, and is specifically designed for valve position measurements. It is a superior alternative to older potentiometer transducers which have poor reliability.

Absolute encoders are devices used to measure lengths or angles and are used as distance gauges in machine tools, in handling and automation technology and on testing units.
Absolute encoders
These output positional information in the form of a numerical value (code). This numerical value is unique across the entire resolution range of the absolute encoder. For this reason no initial reference run is required, as is the case with incremental encoders.
With rotary encoders, a distinction is made between single-turn encoders, which provide a resolution on just a single rotation and then revert to 0, and multi-turn encoders that provide a resolution over several rotations. A further distinction is made between optical and magnetic encoders.

When the Going Gets Tough -
Rugged, compact, reliable ACURO-XR® Series Encoders –
Now offered with Multiturn Technology
Encoders of the new ACURO-XR® series are your reliable partners for applications under harsh operating conditions. They are capable of withstanding highest acceleration rates, mechanical stresses, extreme climatic fluctuations and even underwater operating conditions.
The ACURO-XR® series is characterized by an extraordinarily rugged mechanical design, highest reliability and a long useful life. Its highly robust enclosure and generously dimensioned bearing easily cope with high axial and radial forces up to 300N. The PCB with its evaluation electronics, sensor asic and electronic multiturn features multiple fastening and protection against humidity, corrosion and contact breakage. Extremely high shock accelerations up to 2,000 m/s² and vibrations up to 200 m/s² are no problem for ACURO-XR®.
A high-grade sealing concept protects the encoder against penetrating liquids (IP69k). 12-bit resolution is achieved within one turn, and the encoder is equipped with new, electronic multiturn technology to detect and output the number of turns. It works fully energy-independent, without any gears and contacts, without any moving parts, and without battery.
The max. multiturn resolution has been increased to 24 bits.
ACURO-XR® is accommodated in a compact 58-mm industrial-standard enclosure and excels by its extremely small installation depth of only
32 mm. Its wide temperature range reaching from -40 to +100 °C makes it suitable for a virtually unlimited field of applications.

Incremental encoder is the term given to sensors for recording changes in position (linear or rotating) that can measure both the distance and direction of travel.
They are also known as optical encoders.
Unlike measuring systems that work continuously, incremental encoders have a solid measure with a repeating periodic counting track. The measurement is based on a directional reference and a count.
