Correct Use

Mounting

  • 1.This product is intended to be built into devices so no special measures have been taken against external light interference. When using a DC light sensor in an area exposed to an incandescent lamp or other external light interference, it should be mounted so that the effects of external light interference can be avoided.
  • 2.Mount the sensor securely on a flat surface.
  • 3.Use M3 screws to secure the Photomicro Sensor (use together with spring washers and 6-mm-diameter flat washers to prevent screws from loosening). Use a tightening torque of 0.54 N·m max.
  • 4.Take care that nothing comes into contact with the sensing element of the sensor. Damage to the sensing element will result in poor performance.
  • 5.Before using the sensor, check to make sure that it has not become loose due to vibration or shock.
  •      

Wiring

Surge Prevention ​

  • 1.If there is a surge in the power supply, try connecting a Zener diode (ZD with a voltage of 30 to 35 V) or a capacitor (with a capacitance of 0.1 to 1 ?F), depending on the operating environment. Use the sensor only after confirming that the surge has been removed.
  •  ​​​  ​​​​​​
  • 2.Do not use a small inductive load, such as a relay.
  • ​​​    ​​​​​​
  • 3.If photomicrosensor wires are placed in the same tubes or ducts as high-voltage lines or power lines, induction may cause malfunction or damage. Either wire the photomicrosensor separately or place the wires in separate tubes.
  • 4.Make sure that connectors (commercially available) are securely locked.
 ​

Voltage Output

A sensor with an open collector output can be connected to a counter with a voltage input by connecting a resistor between the power supply and output. Select a resistor with reference to the following example. The resistance of the resistor is normally 4.7 kΩ. The wattage of the resistor is 0.5 W at a power supply voltage of 24 V.

  • 1.A sensor with an open collector output can be connected to a counter with a voltage input by connecting a resistor between the power supply and output. Select a resistor with reference to the following example. The resistance of the resistor is normally 4.7 kΩ. The wattage of the resistor is 0.5 W at a power supply voltage of 24 V.

​​​    ​​​​​​  

Example: EE-SX4173-P3-Z
When inserting a load resistor (R = 5.6 kΩ) in the following device

  • Counter Specifications
  • Input impedance 5.6 kΩ
    Voltage judged as high level (input ON) 4.5 to 30 VDC
    Voltage judged as low level (input OFF) 0 to 2 VDC 

    The high and low levels are found using the following formulas. The input device specifications must satisfy both formulas.

    High level:

     ​​​​  ​​​​​​

Note: Refer to the ratings of the sensor for the residual voltage of the load current.

 

Handling during Wiring

 ​
  • 1.If a force is applied to the connection area between the terminal and connector by bending or pulling the cable after the wiring is completed, the connector contact part or connection area with the cable may be damaged, resulting in contact failure. Make sure that a stress (external force) as shown in the figure below is not applied to the connection area between the terminal and connector when routing and connecting cables or harnesses.
  • ​​​  ​​​​​​
  • 2.Do not perform cord wiring when power supply voltage is applied. Doing so may result in damage.

Other Precautions

Make sure the total length of the power cable connected to the product is less than 10 m.

Design

Design should be made so that light is completely shut off during operation. We recommend that sensing objects are made of metal.
(With an infrared light sensor, infrared light will pass through the sensing object made of resin, resulting in unstable detection.)

Connection with PLC (NPN Open Collector Type)
Mounting should be carried out by reference to the figure below.

Others

  • 1. Do not connect or disconnect the connector while power is applied. Doing so may result in breakage.
  • 2. Do not mount the sensor in the following places because doing so may cause malfunction or damage.
    • 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
    • 5) Make sure that the operating ambient temperature is within the rated range.
  • 3. The sensor may be dissolved by exposure to organic solvents, acid, alkali, aromatic hydrocarbon, and chlorinated aliphatic hydrocarbon solvents, causing deterioration in the characteristics. Do not expose the sensor to such chemicals.
  • 4. An output pulse may occur when the power supply is turned ON depending on the power supply and other conditions. Use the sensor in the stable ready-for-detection state reached in 100 ms after turning on the power supply.
