Rotary encoder MDG 36 E

Modern singleturn / multiturn absolute rotary encoder in robust industrial quality in hollow shaft design, equipped with the most innovative Hall technology. In single-turn mode, the sensor achieves a resolution of 16 bits, i.e. 65,536 steps per 360°, and in multi-turn mode up to 43 bits. The sensor operates without battery and gearbox, making it much more reliable and durable than comparable Rotary encoders. CANopen, SSI and RS485 are available as interfaces.
