Safety first! This applies to mobile vehicles, in particular automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). These are vehicles where there is no direct human supervision. In order to protect the environment, people and machines, and to minimise dangerous moments caused by malfunctions, the operation of these vehicles requires a range of sensor technology. TWK has the right sensors for this task.

Machines are only as safe as their sensors. Many measured quantities must be recorded precisely and reliably.

What makes a good angle, inclination, vibration and displacement sensor? Is it solid measurement acquisition or processing? A fast safety interface or a robust overall design with a few special features? Of course, all of these together represent the prerequisite for a good sensor concept.

Safe angle and speed measurement is a key requirement in vehicles, including autonomous industrial trucks. This is possible with functionally safe and certified encoders with a suitable safety interface on rotary axes or drive motors.

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 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.

The model NBT/S3 PROFIsafe inclinometer from TWK-ELEKTRONIK has now been certified by TÜV according to the EN61508 and ISO13849 standards.

TWK has added the FOI series of incremental encoders to its range of magnetic encoders. An outstanding feature of the FOI series is its fast delivery turnaround time. Orders received by TWK before 11 a.m. will be delivered on the following working day. Over 750,000 versions are available from stock in small quantities.
