Product description
Identification number 406008-2K assigns this version to the incremental Heidenhain ROD 523 rotary encoder within the ROD-500 series. Its exact variant code is 4003.03750 and specifies 3750 lines per revolution. The ROD-523 family uses TTL output signals, a 5 V supply and a mechanically permissible speed of 6000 min⁻¹. The encoder has an integral bearing and connects to the measured shaft through a separate shaft coupling. Its cylindrical basic body has a diameter of 50.8 mm and an axial housing length of 22 mm. The shaft stub has a diameter of 9,518 mm and projects 7.62 mm beyond the mounting face. The complete rigid envelope, including the shaft end, is therefore 29.62 × 50.8 × 50.8 mm in length × width × height order; a flexible connecting cable is not part of this rigid envelope. Three 6-32 UNC-2B mounting threads arranged at 120° intervals have a thread depth of 6.35 mm. Protection is IP64 according to EN 60529. The maximum connected cable length is 100 m. The exact product designation additionally records a weight of 0.68 kg. Identification number, ROD-523 model, variant code 4003.03750, line count, shaft geometry and mounting pattern jointly distinguish this version.
