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-SA
  • Voltage: 24V

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.

FAQ for EE-SA801A

What fiber units work with this amplifier?
EE-SX fiber units (through-beam, diffuse reflective, coaxial). M3 threaded connection. Choose fiber type based on application: through-beam for precise detection, diffuse for proximity sensing.
How do I adjust sensitivity?
Two methods: 1) Manual: adjust potentiometer while monitoring operation LED. 2) Teach: place target, press teach button for automatic sensitivity setting. Teach mode optimizes for specific application.
What's the advantage of fiber optic sensing?
Fiber enables: detection in confined spaces (fiber head is tiny), high temperature sensing (fiber withstands heat), remote sensing (amplifier away from harsh environment), and EMI immunity (light-based, not electrical).
What's the response time?
0.5ms (2kHz response) in standard mode. Ultra-high speed mode: 0.1ms (10kHz). Choose based on application speed requirements. High-speed mode reduces sensing distance.
