Don't go airborne, but better safe than sorry if your application or its environment is at risk of explosion. TWK introduces a new safety encoder for explosion protection according to ATEX, Zone 1 / 21. Additionally with certificate for functional safety SIL2 / Performance Level d. There are many different applications. Simple and complex. Inexpensive and expensive. Non-hazardous and hazardous. Some of them are even explosive. The medium-sized company TWK has suitable sensor technology for almost all areas of application to convert mechanical into electrical measured variables or into electronic data.

With the TRK38, TWK introduces an ultra-compact single-turn magnetic encoder developed with safety-oriented applications in mind. With a diameter of only 38 mm and a length of also 38 mm, the sensor is suitable for mounting in confined installation spaces. The safety level is high: the safety encoder detects position and speed and fulfils the requirements of SIL 2 (IEC 61508) and PL d (EN 13849). The safety-related signals are transmitted via a certified EtherCAT FSoE interface.

The magnetic encoders TRE/TBE from TWK-ELEKTRONIK will be extended by the features 16 Bit in the singletour part and regarding redundancy of the SSI output signal. In the version of a multi-turn encoder TRE, the number of revolutions (12 bits) is also recorded. The position value is available as an absolute value in the standard version.

In order to follow the tradition, another round of rotary encoder experts from SPS-Magazin took place in 2020 at the TeDo publishing house in Marburg, moderated by Dr. Johann Pohany. At the beginning of 2020, seven encoder manufacturers were interviewed on the subject of heavy-duty encoders. TWK-ELEKTRONIK GmbH was represented by Ulf Stark, head of the technical office.

The TBN/TRN-S4 Series has been awarded SIL2 certification by TÜV, thus meeting the requirements for use in safety-related applications. TWK's proven safety series of magnetic encoders is expanded with the TBN/TRN-S4 series, which features increased resolution in the single-turn range (model TBN) and a variety of different applications. The resolution of the sensor system can be up to 16-bits. The detection of the multiturn part, i.e. the number of revolutions (max.12-bit), is done by an absolute multiturn gear (model TRN). This model series is an all-round talent. It covers the entire spectrum, from large and robust to miniature versions, which can be used in areas that do not require extremely high standards for environmental influences and must be cost-effective.

Due to the corona pandemic, companies worldwide must find a solution to maintain business operations in this difficult situation and to protect employees, customers and suppliers from infection. TWK-ELEKTRONIK GmbH has taken various measures to ensure this:

The family of inclination sensors has now been extended by a special device. With this new design it is possible to measure the current alignment - i.e. the inclination or position (360°) - and at the same time exactly the speed in a rotating application.

This year we can proudly report that we will be supporting a junior team. Within the scope of the youth initiative, we will be sponsoring the 2nd M16 basketball team of SC Rist Wedel for the next 3 years.

Long-term product availability makes buying replacements for older products easier.

To make it even easier for customers from France to find each other, TWK is launching the French version of its website this November.
