Technical Overview

The Omron EE-SX770A 2M is a compact, pre-wired slot-type photomicro sensor designed for reliable through-beam detection in dense industrial setups. It features a 5mm slot width, GaAs infrared LED light source, and NPN open-collector output operating in Dark-ON mode. This standard-shaped sensor includes a 2-meter cable, operates on a flexible 5 to 24 VDC power supply, and boasts a thin 4.6mm depth, making it ideal for tight spaces. Built-in load short-circuit protection and dual-sided indicator visibility enhance operational reliability.

Key Features

  • Compact, thin profile (4.6 mm depth) for high-density mounting.
  • Indicator light (red) is highly visible from both sides of the sensor.
  • Pre-wired with a 2-meter vinyl-insulated round cable.
  • Built-in load short-circuit protection.
  • Wide operating voltage range from 5 to 24 VDC.
