Turck RI-12HA3S1-2B256-H1181 Incremental Encoder

The Turck RI-12HA3S1-2B256-H1181 Incremental Encoder delivers precise rotary position and speed feedback for industrial motion control and automation, making it suitable for electric motors, conveyors, packaging equipment, machine tools, and OEM machinery that require reliable incremental sensing with a 1/2 in hollow shaft. Its rugged construction combines a stainless steel shaft and IP67-rated die-cast zinc housing, designed for continuous service operation in harsh environments from -40°C to +85°C. Electrical performance includes 256 PPR resolution, 10–30 VDC operating voltage, and an incremental Push-Pull (HTL) output with inverted signals, with output current up to 30 mA and a maximum pulse frequency of 300 kHz; the device supports speeds up to 6000 RPM (3000 RPM continuous) and uses an M12 × 1, 8-pin male connector. The shaft is 1/2 in (12 mm) diameter, and the long tether arm mounting flange supports 40–75 mm mounting diameters, enabling flexible installation on motors, drives, conveyors, packaging equipment, and OEM machinery. Common replacements include Turck RI-12HA3S1-2B1024-H1181 and RI-12HA3S1-2K1024-H1181 for retrofit or OEM replacement projects.
