Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly. Do not

use it for such purposes.

Power Supply Voltage

Do not exceed the voltage range

indicated in the specifications.

Applying a voltage exceeding the

specifications or using an AC

power supply may result in rupture

or burning.

Faulty Wiring

Do not reverse the power supply

polarity. Doing so may result in

rupture or burning.

Load Short-circuit

Do not short-circuit the load. (Do

not connect to the power supply.)

Doing so may result in rupture or

burning.

Do not use the product in atmospheres or environments that exceed

product ratings.

●Operating Environment

• 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.

●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.

• 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.

● Wiring

Unused Output Lines

Be sure to isolate output lines that are not going to be used.

Connecting to Devices with Voltage Input

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 k

Ω and its

wattage is 1/2 W for a supply voltage of 24 V and 1/4 W for 12 V.

Example: EE-SX95 Series

Load Resistance of 4.7 k

Ω Connected in a Counter

Counter Specifications

The high and low levels are found using the following formulas. The

input device specifications must satisfy both formulas.

High level:

Low level:

Input voltage VL

≤ 1.0 V (Residual voltage for 50-mA load current)

Note: Refer to the ratings of the Sensor for the residual voltage of the

load current.

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.

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.

●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.
