## **Safety Precautions** 

To ensure safe operation, be sure to read and follow the Terms and Conditions Agreement. 

## **Warning** 

**This product cannot be used in safety devices for presses or other safety devices used to protect human life. This product is designed for use in applications for sensing workpieces and workers that do not affect safety.** 

## **Caution** 

**This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes.** 

## **Precautions for Safe Use** 

To ensure safety, observe the following precautions. 

## ● **Wiring** 

**==> picture [32 x 32] intentionally omitted <==**

## **Connection without load** 

If the power supply is connected directly without a load, the internal elements may explode or burn. Be sure to insert a load when connecting the power supply.

## **AND Connection** 

With an AND connection as shown in the figure below, a voltage is applied to Vcc while GND of sensor 2 is not securely grounded. A failure may occur. Do not make this kind of connection. Also in some models, an inrush current may occur in sensor 2 when sensor 1 is turned on, causing failure or malfunction. 

## **Power Supply Voltage** 

Do not use the product with voltage or current in excess of the operating voltage or current. Applying any excessive voltage or current or supplying AC power to a DC-type sensor may cause the sensor to explode or burn.

## ~~oo~~ **Precautions for Correct Use** 

## ● **Mounting** 

- (1 ) Ambient light may cause the sensor to malfunction. In such case, mount the sensor at an angle that ambient light does not enter the receiver lens. Make sure that the sensor is not affected by ambient light. 

- (2 ) Mount the sensor securely on a flat surface. 

- (3 ) Use M3 screws to secure the 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 detected part 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 line, try connecting a Zener diode or a capacitor (with a capacitance of 0.1 to 1 µF), depending on the operating environment. Use the sensor only after confirming that the surge has been removed. 

We recommended use of 20 to 25 V Zener diodes for a 12 VDC power supply.

- (2 ) Do not use a small inductive load, such as a relay.

**----- Start of picture text -----**<br>
Vcc<br>Sensor<br>OUT D<br>+<br>GND<br>-<br>Relay<br>**----- End of picture text -----**<br>


- (3 ) Separate the wiring for the sensor from high-voltage lines or power lines. If the wiring is routed in the same conduit or duct as such lines, the sensor may malfunction or may be damaged by inductive interference. 

- (4 ) Make sure that the connectors are securely locked. 

## ● **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 breakage.

## ● **Design** 

## **Precautions about this sensor** 

A modulated-light type of the sensors is used. When designing, give proper consideration to the power supply and cable lengths used. 

The sensors are more easily affected than the sensors with Nonmodulated Light. 

## **Reasons for Interference from Power and Cable Length on the Sensors with Modulated Light** 

An LED emitter is pulse-lighted to produce modulated light. A large current momentarily flows to the sensors in sync with this pulse timing. This causes a pulsating consumption current. A photoelectric sensor incorporates a capacitor with sufficient capacity, and is virtually unaffected by the pulse of the consumption current. With this sensor, however, it is difficult to have a capacitor with a sufficient capacity. Accordingly, when the cable length is long or depending on the type of power source, it may become impossible to keep up with the pulse of the consumption current and operation may become unstable. 

## **Countermeasures** 

## **<Adding a Capacitor>** 

- Attach a capacitor of 10 µF min. to the wires as close as possible to the sensor. (Use a capacitor with a dielectric strength that is at least twice the sensor's power supply voltage. Do not use tantalum capacitors. A short-circuit may cause the capacitor to ignite due to the large current flow.)

**B5W-DB** 

## **<Extending Cable Length>** 

- Design the configuration so that the maximum cable length for the sensor is 2 m. 

- When using a cable longer than 2 m, attach a capacitor (e.g., an aluminum electrolytic capacitor) with a capacity of 10 μF min. to the wires. The distance between the sensor and the capacitor must be within 2 m. 

Make sure that the total cable length is no longer than 5 m. To use a cable length longer than 5 m, use a PLC or other means to read the sensor output and then transmit the signals using a PLC's communications. 

- Although cables are capable of being extended longer than 5 m, performance is likely to be affected by cable specifications and noise interference from adjacent cables and other devices. 

Voltage drops due to the resistance of the cable material itself will also influence performance. Therefore, factors such as the difference in voltage between the end of the cable and the sensor and noise levels, must be given full consideration.

- (4)Insert a plastic insulator of approximately 10 mm between the sensor and the mounting base. 

## **<Effects of Inductive Noise>** 

- When there is inductive noise in the sensor mounting base (metal), the sensor may enter the same state as light receiving. In this case, ensure that there is no electrical potential difference between the sensor 0 V terminal and the sensor mounting base (metal), or put a 0.47 μF capacitor between the 0 V terminal and the base (metal).

## **<Effects When the Power Supply is Turned On>** 

## **<Countermeasures for Switching Power Supplies>** 

- Take either of the following countermeasures as required if connecting a sensor to a switching power supply. 

- (1)Attach a capacitor of 10 μF min. to the wires as close as possible to the sensor.   (Use a capacitor with a dielectric strength that is at least twice the sensor's power supply voltage. Do not use tantalum capacitors. A short-circuit may cause the capacitor to ignite due to the large current flow.) 

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.

- (2)Connect to the 0-V line of the power source or connect to the power source via a capacitor of approximately 0.47 μF to reduce the impedance of the mounting base to prevent inductive noise from entering the mounting base.
