Overview of Omron E3ZR81

The Omron E3ZR81 is a polarized retro-reflective photoelectric sensor with built-in amplifier. It offers reliable object detection up to 4 meters when used with the E39-R1S reflector. The sensor features a PNP output with selectable Light-ON and Dark-ON operation modes and supports IO-Link communication for smart factory integration. It is housed in a compact square shaped body with a pre-wired 2-meter cable for easy installation.

Key Features

  • Sensing method: Polarized retro-reflective with M.S.R. (Muting Sensitivity Reduction) function.
  • Sensing distance: 100 mm to 4 m using E39-R1S reflector; 100 mm to 3 m using E39-R1 reflector.
  • Output type: PNP open collector, 30 V DC max, 100 mA max load current.
  • Operation mode: Light-ON/Dark-ON selectable.
  • Response time: 1 ms max.
  • Power supply voltage: 10 to 30 V DC with 10% ripple.
  • Communication: IO-Link Ver 1.1 (COM2 - 38.4 kbps) supported.
  • Indicators: Operation LED (orange), stability LED (green), and communication LED for IO-Link.
  • Protection rating: IP67 for dust and water resistance.
  • Operating temperature range: -25 to 55 °C.
  • Robustness: Shock resistance up to 500 m/s²; vibration resistance 1.5 mm amplitude at 10 to 55 Hz.
  • Connection: Pre-wired cable 2 m length.
