The Baumer Absolute Encoder Multiturn optoTurn EAL580-B - EtherNet/IP delivers exceptional positioning accuracy and durability, backed by a total resolution of up to 31 bits and absolute accuracy of ±0.01° in its highest configuration (ST 18 bit / MT 13 bit). This model is equipped with a 10–30 VDC voltage supply and advanced reverse polarity protection, making it safe for continuous operation in electrically noisy environments. With a blind hollow shaft design supporting diameters from ø10 to ø15 mm, it is engineered for integration into tight mechanical systems while maintaining robust signal integrity.
The encoder’s optical sensing method enables non-contact position detection with long-term stability. Its multiturn function and built-in EtherNet/IP interface allow for fast and synchronized communication with industrial controllers, ensuring compatibility with most automation networks. The IP54, IP65, and IP67 ratings certify protection against dust, oil, and water ingress, making this encoder reliable in harsh industrial settings. A rugged zinc die-cast housing with aluminium flange protects internal components without adding weight. The maximum rotational speed of 6000 rpm combined with a starting torque of only ≤0.04 Nm ensures it supports high-speed machinery with minimal mechanical resistance. LED indicators are integrated into the housing for on-site diagnostics, while the flange connector (3 x M12) ensures vibration-resistant, secure connectivity.
The optoTurn EAL580-B - EtherNet/IP is ideal for use in precision-driven environments such as CNC machines, robotic joints, conveyor automation, printing presses, and elevator systems. Its compact ø58 mm flange and versatile shaft design make it suitable for retrofit projects and OEM equipment alike. Maintenance engineers appreciate its long-term reliability, while system designers value its seamless EtherNet/IP integration for real-time control. The multiturn capability is especially useful for tracking full revolutions in position-critical applications, like rotary tables or vertical axes in smart manufacturing setups. For any motion task requiring exact feedback, low latency, and network-ready communication, this Baumer Absolute Encoder is a dependable choice.
