Precautions for Correct Use WARNING ● Installation This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. • It is assumed that EE-SX91 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. Precautions for Safe Use • 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. • Do not short-circuit the load. (Do not connect to the power supply.) Doing so may result in rupture or burning. • Dispose of this product as industrial waste.

Brown Load Black ck Sensor White Blue ((Load short-circuit) Load + − 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 kΩ and its wattage is 1/2 W for a supply voltage of 24 V and 1/4 W for 12 V.

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. • Make sure the total length of the power cable connected to the product is less than 10 m. 7 EE-SX91 Dimensions (Unit: mm) Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
