Sometimes it just has to be more. In this case, TWK's newly developed ABN encoder model has a resolution that divides the full circle of 360° into over 4 million steps. To be precise, in 222 steps - that's a resolution of 22 bits. High accuracy is equally important. This is impressive with better than ±10 arcsec. That is less than ±0.003°. Precise measurements of positions and speeds up to 10,000 rpm are thus possible. The ABN will be available from September 2022.
TWK takes the next step in the direction of 'safety in sensor technology' and introduces the new sensor model TxSN with magnetic sensor system in the series of functionally safe sensors with the established interface standard CANopen Safety (EN 50325-5). This model includes the multiturn encoder TRSN and its small singleturn brother TBSN. It will meet SIL3 level according to EN ISO 61508 and will be certified accordingly and is also ASIL-D compliant according to ISO 26262.
TWK completes its range of NOC electronic cam switches. The established NOCE model with SSI interface is extended by the PLd certified variant according to EN ISO 13849-1:2015. Safe switching contacts supplement the position signal of the integrated encoder to enable the cam controller to be used in safety-critical applications - primarily in the wind industry.
We are proud to announce that for the third year in a row we are sponsoring the M16-2 basketball team of SC Rist Wedel, which is coached by Gundula Laabs (head coach) and Moritz Kröger (co-coach and player ProB).
They are safe in more ways than one: sensors from TWK. Safety in this context means on the one hand functional safety - keywords SIL and PLd - and on the other hand explosion protection - keyword ATEX. The new TRK78/S3 fail-safe over EtherCAT (FSoE) encoder now also belongs to this group.
Another sensor from TWK joins the now long list of SIL2/PLd certified sensors: The newly developed NBT-D/S3 rotor hub sensor with PROFINET interface. The sensor, which was primarily developed for wind turbines, measures the speed of the rotor so that the user knows the operating status of his turbine at all times. Due to the functionally safe design of the sensor, he can trust the output signal of the NBT at any time and design his control concept accordingly. Installation in the rotor is extremely simple and cost-effective: no connection to a drive shaft is required. Instead, it can be placed anywhere near the axis of rotation.
Automated guided vehicles (AGVs) depend on compact, precise and safety-oriented sensor technology - otherwise they cannot navigate in space and move to the target positions. Rotary encoders from TWK, for example the newly developed TRK 38, prove themselves in this area of application.
Apply and deepen the theory taught in the degree programme in practice. This is possible together with TWK. In cooperation with the University of Applied Sciences in Wedel, students and high school graduates have the opportunity to make important contacts with companies during their studies.
In addition to new generations of TRK/TRN/TRT encoders and the new model of a non-shaft-mounted speed sensor NBT-D - there is another way to reliably detect and monitor the speeds of machines or systems in a functional way: The newly developed electronic cam controller NOCIO/S3 with IO-Link interface. It also offers two independently operating switching contacts with SIL2/PLd level, which switch in the event of overspeed or underspeed and can thus initiate safety functions in the system.
As an extension of its portfolio for functionally safe sensors, TWK has developed a special tilt sensor with an integrated gyroscope that makes it possible to measure the position (angle of rotation) and the associated rotational speed in suitable applications, and does so with the simplest possible installation, as no shaft connection is required - called: Rotor hub sensor. Because: measuring rotational speeds is an increasingly important requirement in machines and systems. The position is important, but often not sufficient to ensure efficient and safe operation of a plant. This requires that the sensor system not only outputs measured values of high accuracy, but also works functionally safely.
Too slow, too fast or just right? What is the speed? There are many applications where not only the position - for example a set angle - must be transmitted exactly to the controller, but also the adjustment speed - in other words, the speed of rotation as a measure of the speed. Perhaps, in the context of speed monitoring, the speed of rotation is even more important than the corresponding, momentary position. In addition to the property 'exact', i.e. with high accuracy, the property 'safe', i.e. reliable, is also a prerequisite for sensors in a well-designed, safely operating machine.
Users who require an ultra-compact singleturn absolute encoder for safety-related applications now have a new option. TWK's TRK38 safety encoder, first introduced just under a year ago, has been certified by a Notified Body for applications that meet the requirements of SIL 2 (IEC 61508) and Performance Level d (EN 13849). The sensor's first applications include automated guided vehicles, mobile robots and crane systems.
