Transparent Object (PET Bottle) Detection Compact Photoelectric Sensor

E3ZM-B

Excellent PET Bottle Detection

• New detection method that is independent of bottle shape, position,

and contents.

• Automatic compensation against effects of contamination and

temperature (except E3ZM-B@T).

• Product lineup includes models with adjuster (E3ZM-B@T).

• Detects transparent objects made by PET, resin, and glass.

Refer to Safety Precautions on page 10.

For the most recent information on models that have been certified for

safety standards, refer to your OMRON website.

Parameters require resetting when static electricity causes dust to adhere to the surface of the Sensor

or Reflector, or when the light emission power drops due to temperature- or time-related changes.

Original OMRON light emission control technology greatly reduces the resetting work involved.

E3ZM-B Teaching with No Workpiece Required -- Quick and Easy Setting There is no need for delicate sensitivity adjustments. Simply adjust the optical axes of the Sensor and Reflector, then press the Teaching button twice. This high-reliability design eliminates worries about variations in the sensitivity settings of different operators.

E3ZM-B Technical Descriptions New Technology for Detecting Transparent Objects Exhibiting Birefringence Patented P-opaquing (Polarization-opaquing) Conventional photoelectric sensors for detecting PET bottles depend on refraction due to the bottle's shape or on the attenuation of light intensity caused by surface reflection. However, it is difficult to attain a sufficient level of excess gain with these methods.
