Product description
The identifier 749147-01 designates a Heidenhain incremental rotary encoder from the ERN 1387.035 series for motor speed and position feedback. The full designation ERN 1387.035-2048 identifies the version with 2,048 signal periods per revolution. The encoder has an integral bearing and attaches to the motor by its stator coupling. Its mechanical connection is a tapered shaft with a 9.25 mm functional diameter and a taper ratio of 1:10. Supply voltage is 5 V DC and the analogue output signal is approximately 1 VPP. A straight double-row connector with 14 contacts provides the electrical connection. Permissible mechanical speed reaches 12,000 min⁻¹. The mounted encoder is rated IP40 according to EN 60529. The official mounting drawing specifies a 58.7 mm outside diameter and 35 mm overall depth for the circular encoder contour. The connector area and stator coupling remain within this fixed contour; flexible connecting cables are not included in the dimensions. The product-specific data sheet assigns a mass of 0.2 kg to this identifier. This component is therefore stated conservatively at approximately 0.2 kg. Identifier, full ERN designation, signal-period count, shaft geometry and connector configuration together distinguish the exact version.
