The SICK STEGMANN HG 660 C16 is an incremental rotary encoder delivering 1,024 pulses per revolution, ideal for accurate motion feedback in automation and CNC applications. Operating on a 10–30 V DC supply, it features TTL/RS‑422-compatible quadrature output with a pulse frequency up to ~120 kHz. Encased in a rugged, compact housing (~58 mm diameter), it supports rotation speeds up to ~6,000 rpm and comes with radial cable connection. Built for industrial resilience, the HG 660 C16 withstands vibration and dust exposure—often rated IP66—and is suited for harsh environments requiring reliable, robust encoder performance.
