Excellent PET Bottle Detection

P-opaquing and a Coaxial Optical System Eliminate Dependence on the Bottle's Shape, Position, Transparency, and Contents.

P-opaquing: Polarization-opaquing (Patented)

The E3ZM-B more than triples conventional detection performance, with outstanding stability.

AC3 Function Automatically Compensates Effects of Soiling and Temperature
AC3: Auto Compensation Control for Contamination (Patented)

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.
