Mark Sensor with Stainless Steel Housing

Compact, Photoelectric Sensor with Built-in Amplifier and Teaching Function

E3ZM-V

Another Advance for the E3ZM Series in the Food and Packaging Industries.

Color Mark Detection in a World-standard Size (11 × 21 × 32 mm),
with High-speed Response (50 µs) and Accuracy in Spite of
Sensing Object Movement

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

■ 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.

investigation.

■ IP69K Degree of Protection with an SUS316L Housing

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.

■ Space-saving Design with an SUS316L Housing

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

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

World's Smallest✽ Color-mark Sensor

with Built-in Amplifier

The E3ZM-V provides superior optical performance and yet is
the same size as the E3Z. This compact, high-speed Mark
Sensor remains accurate in spite of sensing object movement.

■ Easy Setting with 2-point and Automatic Teaching

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

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.)

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

● 2-point Teaching (Manual)

● Automatic Teaching (Remote)

■ 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.

Ordering Information

Sensor [Refer to Dimensions on page 13.]

*1. Models with a 5-m pre-wired cable are also available. When ordering, add the cable length to the end of the model number (e.g., E3ZM-V61 5M).
*2. A deviation of ±2 mm (typical value) can be handled for combinations of white, yellow, and black. Refer to page 7 for the detection capability for other color

combinations.

Accessories

Sensor I/O Connectors

(Models for Connectors: A Connector is not provided with the Sensor. Be sure to order a Connector separately.)

[Refer to Dimensions on XS3.]

Note: The outer cover of the cable is made of PVC (polyvinyl chloride), the nut is SUS316L, and the degree of protection is IP67. When high-pressure washing will be

used, select an I/O Connector that has IP69K degree of protection.
