Product description
The Heidenhain 295434-DY incremental rotary encoder belongs to the ROD 426 series and provides 1024 lines per revolution. The output signal is documented as TTL according to RS 422. Supply is 5 V DC (±10 %) and maximum current consumption is 120 mA. Scanning frequency reaches 300 kHz; the mechanically permissible shaft speed reaches 16,000 min⁻¹. The synchro flange has a diameter of 58 mm, a 50 mm centering collar, a 42 mm bolt circle and 3× M4. The solid shaft has a diameter of 6 mm and a usable length of 9.5 mm. Maximum shaft load is 40 N axially and 60 N radially. The enclosure is described as IP64 according to EN 60529. The operating temperature range extends from -40 to +100 °C. Electrical connection uses a male 12-pin M23 connector. Natural convection is specified as the cooling method. The complete identification number 295434-DY distinguishes the variant within the ROD-426 family. Line count, output signal, connection and mechanical interface jointly define the specific product configuration. External dimensions and weight are listed at the end of the specification table and refer to the complete rotary encoder.
