Rotary Encoder – Incremental Feedback Devices for Motion Control
Oriental Motor’s Rotary Encoder series includes ultra-compact, high-resolution incremental encoders designed for tight-space installations.
Technical Features
Housing Types:
• Round shaft models in Ø30 mm or Ø40 mm
• Hollow shaft models in Ø30 mm or Ø40 mm
Resolution Options: 14 options ranging from 100 to 4,000 P/R
Output Formats: Line driver, voltage output, or open-collector (5–24 VDC)
Physical Specs: Ø30 mm or Ø40 mm, depth 22 mm, weight ~33 g (round-shaft), ~38 g (hollow‑shaft)
Signal Outputs: A, B, Z phases for precise position and speed detection
IP65 version: round shaft with Ø40 mm, available as Line Driver or Open Collector type
Benefits & Applications
• Enables detection of rotation differences (belt slippage, pulley deflection) and supports predictive maintenance systems
• Very small footprint; ideal for retrofit or space-constrained designs. Mounting adapter (PEF2) simplifies installation on Ø30 mm shafts
• Easy mechanical alignment of Z-phase output—Z-signal at 180° from connector orientation
