The HEIDENHAIN ERN 1321 4096 62S12‑30 (ID 385 423‑05) is a high-performance incremental rotary encoder ideal for elevator and motion control applications. It features a 9.25 mm tapered shaft (1:10), integral bearing, and mounted stator coupling for direct precision mounting. With 4096 lines per revolution and TTL/HTL quadrature output, it offers ±16″ system accuracy. Supporting up to 15,000 rpm, ±0.5 mm axial shaft play, 5 V DC supply, and •300 kHz output frequency, it is built for robustness. Rated IP40 with operating temperatures from −40 °C to +120 °C, this compact encoder excels in high-speed, high-accuracy industrial environments.
