High-resolution Profinet absolute encoders

Sep 19.09.2023, 4.2 | The new encoders with Profinet interface (picture above) for real-time applications from Turck are primarily used in logistics, food technology and mechanical engineering. The RES (Singleturn) and REM (Multiturn) encoder series rely on the current Profinet encoder profile version 19. They have resolutions of 24 bits for single-turn and up to XNUMX bits for multi-turn devices. Both encoder series support Profinet-Features such as Media Redundancy Protocol (MRP), Link Layer Discovery Protocol (LLDP) and Simple Network Management Protocol (SNMP).

With minimal clock cycles of up to 250 ms and the isochronous real-time mode (IRT), the encoders ensure precise and almost instantaneous communication even in very dynamic applications. The encoders are high-precision and thus enable high-precision positioning and speed control, as required in multi-axis positioning.

The Profinet encoders exist with hollow shaft and solid shaft in a variety of configurations. Various shaft diameters and flange connections as well as easy integration into Profinet networks allow for quick commissioning.

Single and multiturn encoder with solid shaft or hollow shaft

23.09.2021/XNUMX/XNUMX | Turck has added new encoders to its extensive encoder portfolio Encoder with SAE J1939 interface expanded. Especially in the field Mobile Machinery The rotary encoders used in the Industrial and Efficiency Line are available as a single-turn or multi-turn version in a full version or as a hollow shaft version in sizes 36, 46 and 58 mm.

The encoders are mechanically particularly robust thanks to two blocked bearingwhich protect the rotary encoders from vibrations or impacts on the shaft. This makes them more durable than encoders with one shaftstock. The innovative energy harvesting technology of the multiturn J1939 encoders enable wear-free and maintenance-free operation. They count the revolutions without mechanical Transmission or additional Battery. This enables a very compact design.

The users of the new encoders are very flexible: The standard singleturn resolution is 14 bits, the total resolution of the multiturn encoders is 32 bits and can be increased to 43 bits if necessary. This corresponds to more than 500 million representable revolutions. With CAN open models, a maximum of 127 nodes can be configured in a network, but with the J1939 interface they allow up to 254 nodes.

Fast IO Link encoders with COM3

14.12.2020 | Turck has its extensive Encoder Portfolio expanded. Now there is IO Link Versions in Efficiency, Industrial and Premium Line. New rotary encoder models support IIoT solutions with smart data and achieve transmission speeds of 230,4 Kbit. With the portfolio expansion, Turck is underlining its claim as a full-range IO Link provider with numerous devices and masters and offering consistent IIoT Solutions from Sensor to the Coud vice versa.

The latest encoders with IO Link support all encoder segments from the Efficiency, Industrial and Premium Line with COM3 to the latest and at 230,4 kBit / s fastest IO Link interface on the market. It can be used to significantly improve control loops. The rotary encoders have integrated temperature sensors and, if necessary, transmit pre-processed data for the position to the IO Link Master. With their smart data, the devices support IIoT solutions, for example predictive maintenance.

The new encoders are with their blocked bearings particularly robust against impacts and vibrations on the shaft. The energy harvesting technology enables maintenance-free continuous operation because the multiturn IO Link encoders record the number of revolutions even when the power is off - without mechanical gears or additional batteries. Battery changes and regular maintenance work are a thing of the past.

Hall sensor increases process reliability at AWH

For simple and uniform data processing, the rotary encoders are controlled by the IO Link Smart sensor profile (SSP) supported. The SSP defines the data semantics of the IO Link information model across manufacturers in a detailed and uniform manner. Defective devices can be easily replaced using the data storage functionality of the IO Link rotary encoders. The IO Link master provides the new encoder with the necessary device parameters automatically and without additional parameterization.

Encoders for every application from efficiency to premium

With the new encoders, Turck is once again underlining its claim as IO Link full range supplier with numerous devices and masters.

From the sensor to the Coud and back again

This allows the company to offer end-to-end IIoT solutions, from the sensor to the Coud - and back again.

Encoder with IO-Link without bearings and explosion-proof

30.06.2020/24/XNUMX | Turck's non-contact measuring encoder QRXNUMX with IO Link is also available in a variant for explosion-proof areas Zones 2 and 22 or 3GD. Especially in dusty conditions, the encoder's non-contact measuring principle is significantly superior to a bearing-guided optical encoder because it is susceptible to penetrating dust.

With the encoder QR24 The position unit and sensor unit are designed as two completely independent, fully encapsulated units. This protects the encoder against dust, impacts, vibrations and shocks. In contrast to encoders with magnetic position elements, the QR24 rotary encoder has a higher resistance to magnetic interference fields.

The encoder is suitable for the chemical industry, mining or Food industry - especially in mills. Even in the textile industry or wood processing, many applications require one for 3GD approveden encoder.

The QR24-Ex extends Turck's premium line of encoders. He gives his signal over that IO Link Interface V1.1. This makes it easier to set parameters such as the output signal or zero point. The encoder can be used as a singleturn and semi-multiturn rotary encoder. It records the number for the parameter rotation.

Industrial Ethernet encoders and other Industry 4.0 rotary encoders

The encoder uses 16 bits of the 32-bit IO Link signal for the singleturn value, 13 bits for the number of revolutions and the remaining 3 bits for diagnostic data. The Operational status is thus constantly detectable. Maintenance intervals can be planned early. Unexpected machine downtimes are prevented.

Miniature rotary encoder with non-contact resonator measuring principle

30.03.2017/XNUMX/XNUMX | Turck has the compact and wear-free miniature rotary encoder especially for use in mobile machines Ri360 QR20 developed. The new rotary encoder series with protection class IP68/IP69K exceeds the e1/E1 requirements and is built in a compact housing measuring 71 x 64 x 20 mm. Like the larger QR24, it is based on the non-contact resonator measuring principle.

The housing encloses the locator completely and completely covers it from the outside. Alternatively, the encoder can also be positioned above the housing. This design principle makes the assembly very flexible and protects against dust, moisture and mechanical damage when the assembly is covered. The housing is also permanently sealed. Even the often problematic potential leaks such as LED lenses are eliminated because the QR20 is made of a translucent Plastic consists.

The rotary encoder offers a EMC immunity of 100 V/m and is protected against conducted interference according to DIN ISO 7637-2 or SAE J113-11, the so-called load dump. Salt spray, rapid temperature changes, diesel, kerosene or vibrations cannot harm the device. With a temperature range of -40° to +85 °C, there are almost no climatic conditions that could become critical for the QR20. The Ri360-QR20 achieves a resolution of around 0,09° on the output side. The output signal ranges from 0,5 to 4,5 VDC (LU4). If the sensor does not detect a position encoder, the value jumps to 5 V.

Rotary encoder for tight installation spaces in medical technology

The user has the choice between four connection types: German Connectors, AMP connector, M12 connector or Cables with an open end. The position encoder included in the scope of delivery can be flexibly connected to different shaft diameters. Six preset angle variants are available: 20°, 40°, 60°, 90°, 120° and 240°.

Wear-free, non-contact stainless steel incremental encoders

29.03.2017/2017/XNUMX | A variant with an IO-Link interface has been completing the Turck portfolio of wear-free encoders since XNUMX Stainless Steel. The robust encoders of the contactless, inductive rotary encoder series QR24 are specially designed for use in applications with special requirements for cleaning processes or extreme environmental conditions, such as those found in the food or heavy industry.

The EQF24 Series consists of models with SSI, incremental encoder, analog and IO Link output. With V4A stainless steel housing (1.4404) and an active surface made of PA12-GF30 Plastic the device withstands even aggressive chemicals and high pressures in the cleaning process.

As with all QR24 models, there are sensors and position transmitters completely potted and constructed as two independent, absolutely sealed units, which are not affected by vibrations or shocks of the shaft. Wear-prone ball bearings or seals that could cause machine downtimes and thus long maintenance times are not required.

The permanent seal IP69K Thanks to its well thought-out mounting concept, the encoder can be mounted on all common shafts with a diameter of up to 20 mm with the help of adapter rings.

Contactless encoder with fixed pulse rate

27.10.2016/XNUMX/XNUMX | Turck is adding the to its portfolio of non-contact inductive rotary encoders QR24 INCR with a fixed pulse rate. This means that the user can order exactly the right resolution for his application directly from the factory, regardless of whether it is about replacing existing or installing new encoder solutions. Manual setting of a specific resolution via Easy Teach or Pactware is no longer necessary with the preset QR24 models.

There is on request any resolution between 1 and 5000 pulses per revolution. Particularly common resolutions are available directly from stock and can be delivered at short notice. These include the following standard resolutions: 360, 512, 1000, 1024, 2048, 2500, 3600, 4096 and 5000 pulses per revolution. In addition, the following versions can be delivered at short notice (usually within 48 hours): 1, 5, 6, 8, 10, 12, 36, 64, 100, 200, 250, 256, 400, 500, 600, 800, 1200 and 2000 pulses per rotation. The previous variant for individually setting the pulse rate is still available.

Rotary encoders for axes in drives, machines and systems

The INCR variant has more Easy teach functions such as burst, changing the direction of rotation and setting the zero pulse. Thanks to the non-contact principle, the robust sensors of the QR24 series are maintenance-free and wear-free and offer optimal reproducibility, resolution and linearity over a wide temperature range.
