Omron E3ZM-V DATASHEET

Print mark detection photoelectric sensor in compact stainless steel housing

E3ZM-V

The detergent resistant photoelectric sensor
in a robust stainless steel housing provides
reliable detection of all common print marks
in packaging applications.

• White LED for stable detection of differently colored

print marks

• SUS 316L stainless steel housing

• Easy-to-use teach-in button or remote dynamic teach

• Fast response time of 50 µs

FeaturesFeatures

Reliable print mark detection within OMRON’s most popular E3Z sensor family

The E3ZM-V provides reliable print mark detection in the compact sized E3Z housing. For packaging machine makers the E3Z
family offers a complete sensor platform with one mounting concept simplifying installation and machine design.

• Space-saving design with an
SUS316L housing

The compact design reduces volume by 90% compared
to conventional mark sensors.

Water and detergent resistance

The housing is constructed of corrosion-resistant SUS316L,
and the display cover is PES (polyethersulfone).
Both materials are highly resistant to the corrosive effects of
detergents and disinfectants.
The IP69k tight housing construction ensures long sensor
lifetime in often cleaned environments.

Reliable detection of differently colored print marks due to RGB signal processing

• RGB signal processing

The white LED and RGB signal processing ensure the
stable detection of differently colored print marks.
The processing algorithm provides a fast response time of 50 µs.

• Easy setting with 2-point or 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 six times for automatic teaching.
