A New Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use!
Resists Oils and Coolants
The E3ZM-C features a simple shape and
structure that resist oils and coolants,
performance that meets or exceeds any
previous models from OMRON.
The protective structure eliminates the
need for screws to hold a cover, so there
are no worries about loose screws leading
to liquid penetration.
And the model number is laser-marked on
the housing so it's always readable when
the time comes to order maintenance
parts.
The compact, easy-to-use E3ZM-C with
built-in amplifier is ideal for oily
environments.

World's Smallest,
and Yet Robust
The E3ZM-C is the same compact size as
the E3Z, making it the smallest square
metal photoelectric sensor in the world
(according to OMRON investigation).
The SUS316L housing makes it robust,
and removes all worries of the coating
coming off.
Application Precaution
Use the E3ZM-T/-R/-D/-LS in food processing or beverage filling applications where cleaners or disinfectants are present.

Visible Beam.
Long-distance Operation Even
in Dusty, Dirty Environments
The E3ZM-CT@2B uses a bright orange LED to
generate a spot that's visible 1 m away.
And the stronger beam used to achieve a
detection distance of 20 m means that Sensor
operation is possible even in dusty, dirty
environments (response time: 2 ms). It all adds
up to a more visible, more dependable worksite.
Simple, Yet Dependable
M12 Twist-and-Click
Pre-wired Connectors
These Connectors match the XS5
Connectors, which reduce wiring work.
They eliminate the troublesome need to
control torque when tightening connectors,
and remove worries about screws
loosening due to vibration.

E3ZM-C
Designed for the Automotive and Machine Tool Industries
■ Oil-resistant, water-resistant, robust body made of
stainless steel.
■ Same size as the E3Z: The smallest square metal photoelectric sensor in the world.
■ Through-beam Models with an orange spot that's visible 1 m away, and a long distance detection to reduce
the influence of dirt (detection distance: 20 m, response time: 2 ms).
■ Models with M12 twist-and-click pre-wired connectors.
■ Reversed output polarity protection, external light in-
terference prevention algorithm, and RoHS compliance to inherit the E3Z’s reliability.

Let Us Know What You Need
1. Retro-reflective, Diffuse-reflective, and BGS-reflective Models are also available with a 5-m pre-wired cable. When ordering, add the cable
length to the end of the model number (e.g., E3ZM-CD62 5M).
2. Models with no moving parts (i.e., without a sensitivity adjustor or mode selection switch) are also available, as are models with built-in slits
(through-beam, 0.8 m) (e.g., E3ZM-CT83H 2M for no sensitivity adjustment, wire-connection selection of operating mode, and built-in slit).
3. Except for the E3ZM-CL@@H, models with 3-pin M8 connectors are available. When ordering, add “-M5” to the end of the model number (e.g.,
E3ZM-CT66-M5).
4. Through-beam Models are also available with a light emission stop function. When ordering, add “-G0” to the end of the model number (e.g.,
E3ZM-T61-G0).
Ask your OMRON representative for details on any models or specifications you require.

* IP69K Degree of Protection Specification
IP69K is a protection standard against high temperature and high-pressure 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.
