The electronic turn-counting technology used in the new absolute encoders POSI+ makes them very compact: in diameter 58 mm, their length is of only 45 mm. It allows also to design hollow-through shaft encoder, turn counting capabilities up to 16 bits and very high rotation speed. The max. resolution per turn is 524288 positions (19 bits).
Available in SSI and BISS interfaces, the resolution, the codes, high and low range, parity, rest to zero or other value could be programmed. Incremental signals and information about rotation speed and temperature are available.
A SSI to parallel converter built-in a DB37 connector provides parallel interface in the cabinet thus significantly reducing the wiring cost if parallel output is required.
The POSI+ encoders are available with solid shaft of 6 and 10 mm and hollow through shaft of up to 14 mm. Their excellent electro-magnetic protection allows the use in environment with high noise level.

Rotary Optical Encoder is a sensor that converts machinery positional information into corresponding pulse numbers or digital data by photoelectric signals. Therefore, it can detect the speed, position, angular velocity, distance and counts information relating to mechanical machine. It is usually applied on the angle-measuring device and equipment. Hence, it is a very important device in industrial automation field.
Delta ROE series provides precise positioning and speed sensor function. Major applications include main hoist of crane (crane control), CNC tooling machine, elevator, conveyer, textile machine, and storage equipment, etc. industry related machine. Also, it can also be built inside of many kinds of servo motors, brushless DC motor (BLDC) and induction servo motors, and converts rotary motion or position to electronic pulse numbers for phase change, speed and position detection.

The optical rotary encoders are an ideal supplementation to ELGO position controllers and indicators. Thus rotative movements (supplemential to linear measuring systems) can be measured. The rotary encoders working with an optical sensing-principle and incremental square wave outputs.
All ELGO encoder types spend incremental square waves with the channels A and B (UP/DOWN recognition). An index pulse (zero) is available with most types.
The output signals are durable short circuit proofed PUSH/PULL-outputs.

There are two types of rotary encoders: absolute and incremental. Absolute rotary encoders provide a coded angle information and avoid time consuming reference measurements and calculation routines in the controller. Incremental rotary encoders provide a pulse output signal and enable counters and PLC to calculate the position, speed and distance.

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.

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.

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).

Safety relevant equipment must be designed to prevent any damage to persons or to the environment in case of malfunction of the control mechanism or any components. This applies to cranes, lifts, theatre installations and similar constructions.
Sensors with PROFIBUS interfaces must meet these requirements. Therefore the TWK rotary encoders of the CRD/S series have recently been designed according to the PROFIsafe profile for safety technology to the PNO standard No. 3.920. The protocol meets the DP slave class 2 functionality to PNO No. 3.600. The resolution is 13 bits/360°, the maximum measuring range is 4096 revolutions. To guarantee a fail safe operation, a F-CPU master, e.g. Siemens S7 Distributed Safety must be used.
