Dynapar G0566049 AC58/1212ES.41SGH 12-Bit Absolute Rotary Encoder

The Dynapar AC58/1212ES.41SGH is a 12-bit absolute rotary encoder housed in a compact 58mm diameter enclosure, designed for precise position feedback in motion control and industrial automation applications. This model combines rugged construction with flexible communication interfaces, delivering accurate angular position data suitable for servo systems, machinery integration, and feedback loops requiring real-time positional awareness. The encoder features 12-bit resolution with both single-turn and multi-turn capability, delivering accuracy of ±1/2 LSB (±1 LSB above 12-bit resolution). Operating across an industrial temperature range of ?25°C to +85°C, it withstands shock loads to 100 G (3 msec duration) and vibration to 10 G (10–500 Hz), making it suitable for demanding manufacturing and mobile equipment environments. The unit accepts axial and radial shaft loads of 24 lbs and 35 lbs respectively at the 10 mm clamping flange, with maximum shaft speed of 6,000 RPM. Electrical specifications include selectable power supply options (5 VDC ±5% or 10–30 VDC) with current draw of 200 mA maximum. The encoder supports multiple output protocols including parallel binary/Gray code and industrial fieldbus interfaces (CANopen, DeviceNet, Profibus DP, Interbus), enabling integration into diverse control architectures. All electrical connections are short-circuit protected, and the unit carries an IP67 enclosure rating for dust and water resistance. Mounting configurations accommodate both direct shaft coupling and flange mounting, with standard 6 mm syncro or 10 mm clamping flange options. Starting torque is minimal at ?0.2 in-oz, ensuring compatibility with precision drive systems.
