Features
Mount Using M2 or M3 Screws
The EE-SX95 can be mounted using M2 or M3 screws, so it can
easily replace an existing Sensor mounted with M2 screws.
Installation with M2 screws: 18.0
Reliable Best-in-Class Sensing Slot
Depth of 6.5 mm
(Based on April 2013 OMRON investigation.)
A deeper slot helps prevent the sensing object from coming into
contact with the base of the slot, creating greater tolerance in
mechanism design.
6.5mm
Installation with M3 screws: 18.7
Example for the EE-SX950-W
Indication of Sensing Window for Easy
Confirmation of Insertion Depth
The location of the sensing window is indicated on the insertion slot
so that you can visually confirm whether the sensing object covers the
sensing window and easily check the insertion depth.
Bright Indicator for Confirmation from Many
Directions
The bright light indicator can be checked from up to four directions to
enable flexible selection of the installation location.
The sensing object just needs
to extend below this line.

Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly. Do not
use it for such purposes.
Specifications
A Sensor with an open-collector output can be connected to a counter
with a voltage input by connecting a resistor between the power
source and output. Select a resistor with reference to the following
example. The resistance of the resistor is generally 4.7 kΩ and its
wattage is 1/2 W for a supply voltage of 24 V and 1/4 W for 12 V.

●Operating
Environment
Load Short-circuit Protection
•
The EE-SX95 provides load short-circuit protection.
If a load short circuit occurs, the output will go OFF. Check the
wiring and cycle the power supply. The load short-circuit protection
circuit will be reset. The load short-circuit protection will also
operate if the current exceeds the rated load current.
If a capacitive load is being used, make sure that the inrush current
will not exceed the rated load current.
• Do not install the Sensor in the following places to prevent
malfunction or trouble:
1. Places exposed to dust or oil mist
2. Places exposed to corrosive gas
3. Places directly or indirectly exposed to water, oil, or chemicals
4. Outdoor or places exposed to intensive light, such as direct
sunlight
• Be sure to use the Sensor under the rated ambient temperature.
• The Sensor may be dissolved by exposure to organic solvents,
acids, alkali, or aromatic hydrocarbons, aliphatic chloride
hydrocarbons causing deterioration in characteristics. Do not
expose the Sensor to such chemicals.
Other Precautions
• Do not disconnect or wire the cables from the Sensor when power
is supplied to the Sensor, or Sensor damage could result.
• Make sure the total length of the power cable connected to the
product is less than 10 m.
●Installation
• It is assumed that EE-SX95 Sensors will be built into a device.
These Sensors use non-modulated light and are not equipped to
deal with interference from an external light source. When they are
used in locations subject to external light interference, such as
near a window or under an incandescent light, install them to
minimize the effects of external light interference.
• Mount the Sensors securely on a flat surface.
• Use M3 or M2.0 screws to secure the Photomicrosensor. (The
stronger M3 screws are recommended. In addition, use flat
washers and spring washers to prevent the screws from
loosening.) Refer to the following table for the correct tightening
torque.
Screw diameter
Tightening torque
M2.0
0.15 N·m max.
M3
0.54 N·m max.
• If the Sensor is to be used on a moving part, secure the cable
connection point so that it is not directly subjected to stress.
●Other
Precautions
• An output pulse may occur when the power supply is turned ON
depending on the power supply and other conditions. The
operation of the Sensor will be stable 100 ms after turning ON the
power supply.
• Dispose of this product as industrial waste.
