Distances, positions and angles - when a precise positioning is required in the area of industrial engineering, an encoder is just unbeatable.
When making distance measurements the resolution of the encoder is in the micrometer range, when making angular measurements it is equivalent to very few thousandth degrees.
In this way machines and components of all kinds can be positioned very precisely.
Absolute, non-contact length measuring systems, wire-draw encoders and compact measuring wheel encoders complete the offer.

Ever since 1992 TWK encoders are being used for the pitch control of wind energy engines. The position of each rotor blade which has to be adjusted according to the wind intensity and the wind direction is monitored by an electro-optical absolute encoder. The device features a resolution of 12 bits and a serial SSI output interface. The specific item with a 65 mm diameter housing has been chosen with regard to the robust shaft and bearing construction to withstand axial and radial loads up to 250 N, for its IP 66 protection grade and with respect to the long life layout of the electronic circuitry.
A few years ago new electro-magnetic encoders have been developed. They operate with a small permanent magnet which activates an ASIC with integral Hall elements. Various digital and analogue output interfaces are available to comply with special requirements of the user. Several manufacturers of wind engines have already adapted this new type of encoder both with CANopen or voltage output interfaces.
In order to convert the movement of wind vanes into a proportional electrical signal the same electro-magnetic technique has been made available. Whilst the small magnet is directly connected to the shaft of the vane the sensor circuit and the conditioning electronics are settled on a circular pcb. As there is no friction the system works without wear and without any reverse action to the measurement signal. Technical report: PRA 0557).

Angle encoders
The term angle encoder is typically used to describe encoders that have an accuracy of better than ± 5" and a line count above 10000. These devices are used in applications such as NC rotary tables, swivel heads of machine tools, dividing apparatuses, high-precision angle measuing tables, precision devices in angular metrology, antennas and telescopes.
Rotary encoders
Rotary encoders from HEIDENHAIN serve as measuring sensors for rotary motion, angular velocity and also, when used in conjunction with mechanical measuring standards such as lead screws, for linear motion. Application areas include electrical motors, machine tools, printing machines, woodworking machines, textile machines, robots and handling devices, as well as various types of measuring, testing, and inspection devices.
With incremental angle encoders and rotary encoders, the current position is determined by starting at a datum and counting measuring steps, or by subdividing and counting signal periods. Incremental encoders from HEIDENHAIN feature reference marks, which must be scanned after switch-on to reestablish the datum. Incremental rotary encoders with commutation signalssupply the angular shaft position value - without requiring previous traverse - with sufficient accuracy to correctly control the phases of the rotating field of a permanent-magnet three-phase motor.

The RESR and SiGNUM RESM angle encoders feature a ±5 arc second scale graduated axially onto a stainless-steel ring. Available in a range of 20 diameters (from Ø52 mm to Ø550 mm), Renishaw's angle encoders have a low cross-section and a large internal diameter to position easily around large internal rotors, payloads or services.
The rings also feature a unique taper mount which corrects for eccentricity of the rotor/shaft and ensures excellent accuracy, offering easy and robust fine adjustment of the ring's form and all installation tolerances. In addition, the rings offer a very low moment of inertia ensuring that whatever the installation, the system can be positioned with minimal torque and maximum speed.

PRAS1: Contact-Free 360° Angle Sensor in Ultra-Compact M-12 Housing
ASM GmbH sets the new benchmark for angular position sensors with the new development of a magnetic angle sensor in a very compact M12 housing. The PRAS1 sensor provides absolute position measurement over full 360° sensing range and is part of the successful POSIROT® family of magnetic angular sensors. With only a 1/2 inch diameter and overall length of less than 2 inches, this small sensor saves space and can be installed in the tightest locations.
The contact-free and wear-free angular measurement of 0° to 360° is achieved by using a position magnet. PRAS1 has a typical resolution of 0.1° and yields an analog signal through the use of a D/A converter. Three different analog outputs are available: 4-20 mA, 0.5-4.5 V and 0.5-10V. The industrial housing is rated up to IP68.
With its dependable and rugged design, the PRAS1 angle sensor is well suited for angle monitoring in a wide variety of heavy duty applications such as factory automation equipment, variable valve controls, mobile working machines, etc.

Gill angle position sensors are ideal for monitoring angular position in applications where high dither life of the angle sensor is essential. All Gill angle sensors use inductive technology to sense the position of a metallic object which is mounted to the application. There is no contact between the sensor and the moving part which gives infinite dither life.
Gill angle sensors are fully sealed with no internal moving parts, ideal for applications subject to extreme environments where grime, moisture and vibration are factors.
All of the angle sensors below are capable of monitoring 0-45 and can be configured to operate over the exact measurement range required, giving the highest possible accuracy for each application.
Sensors suitable for Angular position applications are shown below. Please select the sensor which best suits your application to view technical specifications, dimension details and application ideas.

The combination of a coder with ends of the road in the same case increases the reliability and the safety of the machines, because of two independent checking circuits in the same case.
The coder integrated provided information uninterrupted of the movement in 5-30 VDC with a resolution from 100 to 5000 increments. The programmable ends of the road, the catch of origin are regulated freely with the position wished.
The adjustment of the ends of the road is very simple: the case is assembled on the machine, the machine is then led manually to its limiting position, the end of the road is positioned with a key of programming. This procedure is repeated for the other end of the road.
The case is well protects by its cap against dust or any external intervention; all the signals are cabled on a connector with the back of the case.
These cases can also be provided with potentiometers.
COMP' AUT will be able to best advise the customer in the choice of the case being appropriate for its application.

The MLX90609 Angular Rate Sensor is a full gyroscopic system. A single SMD package contains a high performance Silicon micro machined sensor with signal conditioning circuitry. It operates from 5V supply and is designed for demanding automotive applications. The MLX90609 delivers two output signals proportional to the angular rate parallel to the assembly surface. One of the output signals is in an analog voltage format (the output is 2.5V at zero angular rate and the full scale angular rate produces an output of 4.5V or 0.5V depending on direction of rotation) and the other one is in a digital SPI format.
