The G0M2H: Baumer Through Hollow Shaft ø14 mm Absolute Encoder is engineered with precision optical sensing to deliver multiturn feedback with an absolute accuracy of ±0.025°. Powered by a wide voltage supply range of 10...30 VDC, it supports SSI and optional Incremental A 90° B interfaces—ensuring seamless integration into most automation systems. The encoder is designed with a through hollow shaft of ø10...14 mm, allowing direct mounting on machine shafts without couplings. Durability is ensured through its robust aluminium housing and flange, backed by IP54 or optional IP65 protection. It operates at speeds up to 6000 rpm (mechanical and electrical) and maintains stable performance under shock (up to 200 g) and vibration (up to 10 g) conditions, according to EN 60068 standards. Its low starting torque of ≤0.04 Nm ensures smooth operation even in energy-sensitive systems. This makes the Baumer G0M2H a highly dependable encoder in both harsh and controlled environments. Installation is flexible via M23 connectors or a 1-meter cable, enabling easy routing inside panels or enclosures.
The Baumer G0M2H encoder is widely used in industries that demand accurate position control with through-shaft configurations. Its common applications include rotary indexing tables, robotic joints, conveyor drives, servo motors, and automated crane systems. The through hollow shaft design allows direct fitting on drive shafts without the need for additional mechanical components, reducing wear and improving system alignment. Engineers prefer this model when space constraints and alignment precision are critical. With its multiturn capability, optical sensing accuracy, and high-speed operation, the G0M2H meets the real-world demands of both legacy systems and modern smart factories.
