Multiturn absolute rotation sensor
The TR series encoders are high-quality magnetic rotary encoders, certified to SIL2/PLd or SIL3/PLe (in accordance with IEC 61508 and ISO 13849). The encoders are designed for extremely accurate position and rotation measurements, even in demanding environments. The magnetic sensor system ensures precise position detection with a resolution of up to 16 bits (65,536 steps). Thanks to the integrated multiturn transmission, 4,096 revolutions can be measured.
For position detection where safety is paramount, the encoders are equipped with four redundant magnetic chips, with two independent microcontrollers continuously calculating the position data. The resulting SRDO (Safety Related Data Object) message is only accepted if the values from both microcontrollers match, significantly increasing reliability. Additional checks such as CRC checks, timing, and voltage monitoring ensure that error messages are detected immediately.
The electrical connection can be made via an M12x1 connector with bus in and bus out options or via a fixed cable. These encoders are available with all common communication options.
Thanks to their robust design, advanced technology and high safety standards, the TR series encoders provide a reliable solution for applications where precision and safety are crucial. The encoder is available with a choice of housings (stainless steel or aluminium) and supports all standard communication protocols.
This series is available with a gear. The measuring gear is made from a durable, elastic plastic that enables backlash-free measurement with rotary encoders. This prevents incorrect measurement values when the direction of rotation is reversed. The tooth profile is derived from the involute gear profile. The backlash-compensating measuring gear has been developed for use in cranes, wind turbines and mobile machinery. The gears are available in various sizes.
