Used encoders (all tested and working)

The HEIDENHAIN ERN 1381 1000 62S12-30 (ID 534 118-07) is a high-precision incremental rotary encoder designed for demanding motion control applications. It offers 1000 signal periods per revolution with TTL or 1 Vpp output, ensuring accurate and reliable position feedback. Equipped with a 9.25 mm tapered shaft (1:10), integrated bearing, and stator coupling, this encoder allows direct shaft mounting and compensates for axial and radial misalignment. With speeds up to 15,000 rpm, system accuracy of up to ±16 arc-seconds, and operating temperatures from –40 °C to +120 °C, it is ideal for CNC machinery, robotics, and automation systems.
