The Baumer optoTurn EAL580-B - EtherCAT encoder is powered by a 10–30 VDC supply and is equipped with robust reverse polarity protection for reliable operation in demanding environments. With a multiturn function and an impressive total resolution of up to 31 bits, it delivers exceptional accuracy—±0.01° for 18-bit single-turn and 13-bit multiturn operations. The encoder uses an optical sensing method and includes 4 integrated LED indicators for clear status feedback, enhancing real-time diagnostics.
This Blind Hollow Shaft Encoder supports shaft diameters ranging from ø10 to ø15 mm and is built to withstand harsh industrial conditions. It features IP54, IP65, and IP67-rated protection, a maximum operating speed of 6000 rpm, and vibration and shock resistance as per EN 60068-2 standards. The housing is made from zinc die-cast with an aluminium flange, ensuring durability without adding weight—at just 500 g. Connectivity is handled through a 3xM12 flange connector that ensures secure, high-speed data transmission.
The optoTurn EAL580-B - EtherCAT is widely used in servo motors, automated guided vehicles (AGVs), robotic arms, and industrial machinery where real-time feedback and precise angular positioning are critical. Its compact ø58 mm flange design allows seamless integration into space-constrained control cabinets or rotating equipment. With high resolution and EtherCAT compatibility, it’s the preferred choice for advanced motion control systems requiring high-speed, synchronized feedback. Whether you're upgrading existing systems or designing new automation frameworks, this encoder delivers the stability and precision engineers trust.
