Description
The Baumer GM400.Z103 is a solid-shaft absolute encoder featuring a clamping flange, designed for multiturn SSI applications. With an optical sensing method, it provides accurate positioning with a single-turn resolution up to 14 bits and multiturn resolution up to 16 bits, offering absolute accuracy of ±0.025°. Its electronic zero-point setting and counting direction input enhance flexibility in installation and calibration.

This encoder supports robust operation with a voltage supply of 10–30 VDC (or 5 VDC ±10%), reverse polarity protection for 10–30 VDC, and very low consumption (≤50 mA at 24 V, ≤80 mA at 5 V). Initialization occurs in just 20 ms after power-on, ensuring rapid readiness for automation systems.

Mechanically, the GM400.Z103 is built for durability, with an aluminum housing and flange, and a rotor with a moment of inertia of 20 g·cm². It tolerates shaft loads up to 20 N axial and 40 N radial, while maintaining performance in temperatures from –25 °C to +85 °C (optionally –40 °C to +85 °C) and up to 95% relative humidity.

The encoder offers versatile outputs, including SSI and optional incremental A/B channels, linedriver RS422, and diagnostic push-pull signals. Its design ensures maximum resistance against magnetic fields, making it ideal for industrial and motion control environments requiring high reliability and precision.
