Omron E3Z-D81 Compact Photoelectric Sensor with Built-in Amplifier, 12-24V DC

Diffuse-reflective square-type sensor, PNP output, pre-wired

Overview

This is an Omron E3Z-D81, a compact, square-type photoelectric sensor with a built-in amplifier, using diffuse-reflective sensing with an infrared LED (870 nm) light source. It detects white paper (100 x 100 mm) at up to 100 mm, operates on a 12-24V DC supply, and provides a PNP open-collector output with selectable Light-ON/Dark-ON operation. Rated IP67 and built with output/reverse-polarity protection circuits, it's designed for reliable presence and object detection in industrial automation environments.

Key Features

  • Diffuse-reflective sensing: Detects white paper (100 x 100 mm) at up to 100 mm, with differential distance of 20% max. of sensing distance.
  • Fast response time: Operate or reset in 1 ms max., suited to high-speed detection applications.
  • Selectable operation mode: Light-ON/Dark-ON switchable to fit different application logic.
  • Robust protection circuits: Output short-circuit protection, output reverse polarity protection, and power supply reverse polarity protection built in.
  • IP67 rated: Fully sealed against dust and water ingress for demanding industrial environments.
  • Dual status indicators: Orange operation indicator and green stability indicator for quick visual diagnostics.
  • Wide ambient tolerance: Rated for -25°C to 55°C operation and high ambient illuminance resistance (sunlight up to 10,000 lx).
