External Encoder

Industrial fan technology for effective, reliable, and flexible cooling.

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
