Product Overview

EE-SA801A is part of Omron EE photomicrosensor family and is commonly used for edge detection, part passage confirmation, and reference position sensing in compact machine mechanisms. Slot sensors are practical when integrators need fast response and consistent optical geometry without complex external alignment fixtures. This model is often deployed in labeling modules, feeder tracks, counting stations, and compact handling modules where mechanical tolerances and vibration demand stable detection behavior. During design, engineers should validate emitter-receiver alignment path, target material characteristics, and contamination exposure to sustain reliable signal quality over long operating hours. For production environments, cable routing, shielding, and switching interface compatibility with PLC input modules should be reviewed early to reduce commissioning issues. EE-SA801A is typically selected when a compact optical package with predictable installation geometry is preferred over larger diffuse or retroreflective sensing methods.

  • SKU: EE-SA801A
  • Series: EE photomicrosensor family

Best-Fit Applications

  • Part counting and passage detection in feeder tracks
  • Reference flag sensing on indexing mechanisms
  • Media edge detection in labeling and print modules
  • Presence verification in small assembly fixtures
  • Home-position detection on compact actuators
  • Transfer station object confirmation before next cycle

Buying Checklist

  • Check slot geometry against target width and mechanical tolerance stack-up.
  • Validate output interface voltage and input current limits with PLC hardware.
  • Assess contamination risk from dust, oil mist, or debris in the sensing gap.
  • Confirm cable routing and strain relief to avoid signal instability during vibration.
  • Include periodic cleaning and inspection in preventive maintenance procedures.
