Explain cleaning precautions for Photomicrosensors


Explain cleaning precautions for Photomicrosensors.



Refer to Explanation for cleaning built-in type Photomicrosensors.



Most built-in type Photomicrosensors can be cleaned with the some limitations; however, actuator models (e.g. EE-SA105) cannot be cleaned because flux residue may affect sliding performance.

  1. Types of detergents
    Most Photomicrosensors use polycarbonate as the housing material, and depending on the type of solvent, the housing may melt or crack. Use the following check results by Omron as a guide to fully evaluate the product for external abnormalities (e.g. melting and cracking) after cleaning.
    Select and use cleaning agents in compliance with relevant laws and environmental considerations.

Check Results by Omron

Ethyl alcohol No problem
Methyl alcohol No problem
Isopropyl alcohol No problem
Trichloroethylene Problematic
Acetone Problematic
Toluene Problematic
Water (hot water) Lead may rust under certain conditions.
  1. Cleaning method
    Perform cleaning under the following conditions unless otherwise specified by the datasheet. Contamination of the cleaning agent and flux residue may affect the optical properties of the sensor, or the material of the housing may deteriorate.
    After cleaning, dry well in a place with little dust.
Immersion cleaning No problem
Ultrasonic cleaning Varies depending on sensor model, PCB size, etc. Check in advance for abnormal characteristics (e.g. disconnection).
Brushing Markings may disappear or the light projection surface of reflection models may be damaged, deteriorating the performance. Check in advance for external appearance.
