- The Dark-ON/Light-ON (selectable) models are normally used as dark-ON models. To use them as light-ON models, short-circuit the L terminal and positive (+) terminal. 

An EE-1001-1 Connector with the terminals already short-circuited is also available.

Note: For details, refer to the Photomicro Sensors Accessories on EE- @ which can be accessed from your OMRON website. 

- EE-1009- or EE-1010-series Connectors have a builtin locking mechanism to prevent cable disconnection when only the cable is pulled. To remove the Connector from the Sensor, grip the top and bottom of the Connector firmly and push into the Sensor once before pulling out. The locking mechanism prevents the Connector from being removed by pulling on the cable only and enables removal only when the Connector (housing) is pulled.

## **Safety Precautions** 

## **Refer to** _**Warranty and Limitations of Liability**_ **.** 

## **WARNING** 

**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 Correct Use** 

Make sure that this product is used within the rated ambient environment conditions. 

## ● **Wiring** 

## **Soldering** 

- When direct soldering to the terminal, use the following guidelines. 

- **Soldering Conditions** 

|**Item**|**Temperature**|**Permissible**<br>**time**|**Remarks**|
|---|---|---|---|
|Soldering<br>iron|350°C<br>max.|3 s max.|The portion between the base of<br>the terminals and the position<br>1.5 mm from the terminal base<br>must not be soldered.|



- The terminal base uses a polycarbonate resin, which could be deformed by excessive soldering heat, resulting in damage to the product’s functionality. 

## ● **Sensitivity Adjustment** 

## **Use the special screwdriver (sold together) for sensitivity adjustment.** 

- When an excessive force is applied to sensitivity adjuster, it may be damaged. 

- The shaft of the sensitivity adjuster is charged. Connect a DC power supply incorporating an insulated transformer to the photomicrosensor. Do not connect a DC power supply incorporating an autotransformer or the user may receive an electric shock when adjusting the sensitivity.

Autotransformer<br>Power  +<br>source − Sensor<br>Power  +<br>source − Sensor<br>Insulated transformer<br>**----- End of picture text -----**<br>


## **Cable Extension** 

- When extending the cable, use an extension cable with conductors having a total cross-section area of 0.3 mm[2] . The total cable length must be less than 10 m. 

## ● **Installation** 

The photomicrosensor is built into the device being used and so is not equipped to deal with interference from an external light source. When using the sensor in an area exposed to an incandescent lamp, install so as to minimize the effects of external light sources.
