The NEMICON OEW2‑01‑2MHC is a compact incremental rotary encoder from the OEW2 series, offering 100 pulses per revolution (PPR), AB quadrature output with 90° phase difference plus a zero signal, and a high‑voltage open‑collector output (HC type). It is designed for small shaft applications where reliable feedback and compact size are critical.

⚙️ Key Specifications

• Series / Model: OEW2‑01‑2MHC
• Encoder Type: Incremental rotary encoder (shaft type)
• Resolution: 100 pulses per revolution (01 = 100 PPR)
• Output Mode: AB quadrature signals (90° phase difference) + Zero signal (2M option)
• Output Circuit: HC = High‑voltage open collector output
• Supply Voltage: 5–12 V DC (depending on variant)
• Cable Length: Standard 2 m (custom lengths available)
• Mounting: Miniature shaft encoder, compact housing for tight spaces
• Operating Temperature: −10 °C to +60 °C (typical for OEW2 series)
• Applications: Counters, small motors, robotics, automation systems requiring compact feedback devices

📊 Product Highlights

• Compact design: OEW2 series is known for miniature encoders, ideal for space‑constrained installations.
• Quadrature + zero signal: Provides directional information and a reference pulse for precise positioning.
• Flexible outputs: Available in multiple output types (open collector, push‑pull, line driver, CMOS). The “HC” variant supports high‑voltage open collector.
• Resolution range: OEW2 family supports 20–3600 PPR, with the “01” variant specifically at 100 PPR.

🔍 Hidden Insights

• Model code breakdown:
  • OEW2 = Encoder series
  • 01 = 100 PPR resolution
  • 2M = AB quadrature + zero signal output
  • HC = High‑voltage open collector output
• Application fit: The 100 PPR resolution is relatively low, making it suitable for speed monitoring or coarse positioning rather than ultra‑precise control.
• Family scalability: If higher resolution is needed, other OEW2 variants (e.g., 1024 PPR, 2048 PPR, 3600 PPR) are available with the same mechanical footprint.
