The Heidenhain 735117-03, model ROD 431.026-2048, is an industrial-grade incremental rotary encoder designed for precise angular position and speed measurement on motor shafts and rotating machine components in CNC systems, automation equipment, and servo drives. Featuring a 2048-line-per-turn resolution with photoelectric scanning technology, it generates high-accuracy A, B, and N (reference) square-wave signals via HTL interface (push-pull), ensuring compatibility with most PLCs and motion controllers while supporting scanning frequencies up to 300 kHz for traverse speeds exceeding 6000 rpm.
With a robust blind hollow shaft design (15mm diameter) and clamping ring mounting, it provides backlash-free coupling, axial/radial shaft load capacity up to 150N/350N, and exceptional vibration/shock resistance (100 m/s²/1000 m/s²). The IP40-rated aluminum housing withstands typical industrial contaminants, while the 12-pin M23 connector with axial/radial cable options simplifies integration. Operating across an extended -40°C to +100°C range with low power consumption, it offers maintenance-free operation (>10^9 signal states), diagnostic LEDs, and natural aging compensation, making it ideal for high-duty-cycle applications requiring reliable commutation and positioning accuracy.
