Omron, E3ZM-V Series

Color Mark Sensors Now Join the E3ZM Series of Photoelectric Sensors for the Food Industry

Space-saving Design with an SUS316L Housing (E3ZM Standard Size)

The compact design reduces volume by 90% compared with previous OMRON models.

And the world-standard dimensions contribute to standardized installation specifications.

Coaxial Optical System in a Compact Design

Although the E3ZM-V is only 11 × 21 × 32 mm, it uses a coaxial optical system.

Even if the sensing object is inclined, reflected light is captured with the coaxial optical system to provide stable detection.

IP69K Degree of Protection with an SUS316L Housing (Same Durability as the E3ZM)

The housing is constructed of corrosion-resistant SUS316L, and the display cover is PES (polyethersulfone). Both materials are highly resistant to the effects of detergents and disinfectants. IP69K degree of protection also allows the E3ZM-V to withstand washing with high-temperature, high-pressure water. This makes the E3ZM-V well suited to use in sites requiring a high level of hygiene.

Cutting-edge Technologies Give This Color Mark Sensor Its Compact Size and Superior Performance.

Improved Color-difference Discrimination, RGB Signal Processing

Discriminates fine color differences which was difficult for previous OMRON models.

Teaching enables automatic selection of ideal colors.

Plus, response is a fast 50 μs for both ON and OFF operation.
(Patent pending)

Easy Setting with 2-point and Automatic Teaching

2-point Teaching (Manual)

Simply aim the beam spot at the mark portion and background portion, and press the teaching button.

Automatic Teaching (Remote)

Send a pulse to the remote control input and have the mark pass by seven times for automatic teaching.
(Note: There is no answer-back output.)

*4. IP69K Degree of Protection Specification
IP69K is a protection standard against high temperature and highpressure water defined in the German standard DIN 40050, Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14 to 16 liters/min. The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0°, 30°, 60°, and 90° while rotating the test piece on a horizontal plane.
