TWK has introduced an ultra compact single turn magnetic encoder, trk38, which is designed for safe application. Its diameter and length are only 38mm, so it is suitable for installation in narrow installation space. Its security level is high: the safety encoder can detect position and speed, and meet the requirements of SiL2 (IEC61508) and PLD (en13849). Safety related signals are transmitted through the certified ethercatfsoe interface.

Compact appearance, but still with high power density: packaging has become a key factor in many fixed and mobile machines. TWK’s new products can meet this demand. The size of trk38 single turn magnetic encoder is only 38×38 cm (diameter x length), so the appearance is very compact. The weight is also very low, about 60 grams.

At the same time, users don’t have to compromise on performance. Trk38 detects position and speed in a safe way, and can meet the requirements of SiL2 (IEC61508) and performance level (en13849). The positioning resolution is 16 bits per circle. The certified ethercatfsoe interface ensures the reliable transmission of safety related signals to the superior controller or safety relay, as well as the programming of sensors.

Compact, robust and safe: customized trk38 single turn encoder for safe applications

Trk38 has a very compact size and high quality design, and its price is competitive compared with alternative products such as sine cosine encoder and incremental encoder. The aluminum housing and overall design of trk38 enable it to provide long service life even under adverse conditions such as vibration and shock loads. Its non-contact and wear-free measurement principle has also made a significant contribution to this.

With this feature, trk38 is suitable for a variety of security applications. Like many products developed by TWK, it is also developed according to the requirements of customers, who have not been able to find this extremely compact and robust single turn encoder for security applications from relevant suppliers before.

TWK is well prepared for such requirements. Based on a comprehensive range of sensors developed for demanding applications, developers adjust the relevant basic model parameters, such as size, shell design, electrical characteristics, interfaces, and mechanical and electrical designs commonly used to integrate into surrounding structures, according to the individual needs of customers. This is not only suitable for traditional sensors, but also for sensors that undertake the task of functional safety.

TWK can produce such customized sensors in small quantities. The global distribution network creates a prerequisite for close cooperation in the development or adjustment process, and the extremely flexible production enables TWK to consider the individual needs of customers in the sensor production process. Therefore, TWK can develop other models of trk38, such as other interface and communication options.
