The Heidenhain ERN1387.035-2048 (ID 749147-01) belongs to the ERN series of incremental rotary encoders optimized for high-performance motion control systems. Featuring 2048 lines per revolution with ±20″ system accuracy, it utilizes advanced photoelectric scanning with plane-surface stator coupling for backlash-free transmission and large mounting tolerances. The encoder generates ~1 Vpp sinusoidal signals (A+, A-, B+, B-, R+, R-) via 14-pin connector, supporting cutoff frequencies up to 400 kHz for traverse speeds exceeding 6000 rpm.

Designed for direct motor shaft integration, it features integrated bearing construction with robust vibration/shock resistance (up to 300 m/s² at +100°C), operating on low-voltage DC 3.6-14V supply with maximum power consumption of 700mW. The compact aluminum housing withstands industrial contaminants and temperatures up to +115°C, making it ideal for elevator drives, CNC spindles, and servo applications requiring maintenance-free operation over >10^9 signal states.
