The Baumer Solid Shaft with Clamping Flange optoTurn EAL580-SC - EtherCAT is built to deliver reliable, high-resolution performance in multiturn applications. It features a robust 10–30 VDC voltage supply with reverse polarity protection and supports a maximum total resolution of up to 31 bits, enabling fine-grained absolute position detection. With optical sensing, it ensures accurate non-contact measurement over time, supported by ±0.01° accuracy in high-resolution configurations. Its solid shaft design (ø10 x 20 mm with flat) and compact ø58 mm clamping flange allow stable mounting on motor shafts and high-speed drive systems.
The encoder operates at speeds up to 10,000 rpm (mechanical) and 6,000 rpm (electrical), making it suitable for dynamic motion control environments. The starting torque is exceptionally low at ≤0.03 Nm (IP65/67) and ≤0.015 Nm (IP54), reducing mechanical load and enhancing system efficiency. A 3xM12 flange connector ensures secure, vibration-resistant data transmission. With IP54, IP65, and IP67 protection ratings, this encoder withstands dust, water spray, and temporary immersion, while operating reliably in harsh conditions from -40°C to +85°C. It is enclosed in a rugged zinc die-cast housing with an aluminium flange and includes 4 integrated LED indicators for real-time diagnostic status.
The optoTurn EAL580-SC - EtherCAT is trusted across a wide range of applications—from servo motor feedback in robotics to high-speed rotary tables in CNC machines. It is ideal for textile machinery, elevator drives, packaging systems, and printing automation where accurate shaft positioning and EtherCAT-based communication are essential. Engineers prefer this model for its compact build, high-speed tolerance, and seamless EtherCAT interface integration. With its multiturn capability and rugged housing, it ensures long-term reliability in factories implementing Industry 4.0 systems. Whether retrofitting existing setups or designing new smart machines, this Baumer Solid Shaft with Clamping Flange encoder delivers the performance, speed, and durability demanded by modern automation.
