Multiturn encoder EAM36 Without batteries - based on Wiegand effect

PEWATRON introduces ELTRA’s new multiturn encoder EAM36 with SSI interface. Wherever drives need compact and cost effective feedback systems, or in applications demanding particularly compact size, or customer specific applications fields, the EAM36 series represents an excellent choice with its robustness, high resolution (51 bit in total), small size (only 36 mm of OD and 43 mm of length), reliability and gear & battery free operation. What makes the EAM36 encoder series special is the unique technology used to count the number of rotations that the device does. The solution that the Eltra designers developed is based on the 'Wiegand effect'. The key feature of the EAM 36multi-turn encoders is that the turn counter mechanism is self-powered. The encoder shaft rotation generates enough electrical energy - independently from the rotating speed - to trigger the turn counter and to save the event in a non-volatile random-access memory (FeRAM). Eliminating the traditional mechanical gear or electronic counter with battery ensures a higher reliability and a maintenance free solution. The magnetic technology is the key contributor for ruggedness and compact size of the EAM36 complementing the well known ELTRA's multi-turn optical series (EAM58, EAM63).

Features: Applications:  Battery- and gear-free operation  Medical devices  Compact size (OD: 36 mm, solid shaft housing  Heavy construction machinery length: 43 mm )  Automated doors  High resolution (51 bit total)  Elevator systems  Electronic zero set  High-demanding factory automation systems  Wide working temperature range (-20/+100°C)  Quick and simple assembly  High reliability application

 SSI Interface Text length 1332
