Description
The Baumer GM401.Z29 is a high-performance absolute encoder designed for precise position and motion measurement in industrial environments. Featuring a solid shaft with synchro flange and optical multiturn technology, it delivers a maximum resolution of 14 bits singleturn and 16 bits multiturn, ensuring accurate readings across a wide range of applications.

Equipped with a robust optical sensing method and SSI interface, this encoder supports additional incremental outputs and allows electronic zero-point setting and counting direction input. Its design provides excellent resistance against magnetic interference, making it reliable even in electrically noisy environments.

The GM401.Z29 operates on a voltage supply of 10…30 VDC (or 5 VDC ±10%) with reverse polarity protection and low current consumption. The encoder’s high-speed capability (up to 10,000 rpm mechanically and 6,000 rpm electrically) and fast initializing time (20 ms) allow quick system response and seamless integration into automated systems.

Engineered for durability, the GM401.Z29 functions across temperatures from -25°C to +85°C (optionally down to -40°C), with relative humidity tolerance up to 95% non-condensing. UL approved (E63076), this encoder ensures reliable, long-term operation even under challenging industrial conditions.
