6 / 9 page EE-SX91 6 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. • 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. ● Installation • 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. • 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-SX91 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 100-mA load current) Note: Refer to the ratings of the Sensor for the residual voltage of the load current.
