Rotary encoder MDG 58 A

Modern singleturn / multiturn absolute rotary encoder in robust industrial quality, equipped with the most innovative Hall technology. In single-turn mode, the sensor achieves a resolution of 16 bit, i.e. 65,536 steps per 360°, and in multi-turn mode up to 43 bit.

Compact design with bus cover with 3x M12 connections for bus connection. In addition, the Rotary encoder has 2 colour duo LEDs to indicate operating status and bus status as well as 2 L/A LEDs.
