EE-1006A (Can be used only with EE-1006 Connectors for the Photomicrosensors listed above.) 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. 1 EE-SY671/672 Ratings and Specifications Item Models EE-SY671, EE-SY672 Sensing distance 1 to 5 mm (Reflection factor: 90%; white paper 15 × 15 mm) Sensing object Transparent or opaque: 15 × 15 mm min.

Precautions for Correct Use • The shaft of the sensitivity adjuster is charged. Connect a DC Make sure that this product is used within the rated ambient power supply incorporating an insulated transformer to the environment conditions. photomicrosensor. Do not connect a DC power supply ● Wiring incorporating an autotransformer or the user may receive an Soldering electric shock when adjusting the sensitivity. • When direct soldering to the terminal, use the following guidelines. Autotransformer Soldering Conditions + Power Sensor source Permissible − Item Temperature Remarks time The portion between the base of Soldering 350°C the terminals and the position 3 s max. iron max. 1.5 mm from the terminal base must not be soldered. Power + source Sensor − • The terminal base uses a polycarbonate resin, which could be deformed by excessive soldering heat, resulting in damage to the Insulated transformer product’s functionality. Cable Extension • When extending the cable, use an extension cable with conductors 2 having a total cross-section area of 0.3 mm . 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. 4 EE-SY671/672 Sensitivity Adjustment with Background Object Point A Point B Setting Check Background object Background object Background object A C C Sens- Ad- Black paper with small B B ing juster reflection factor condi- indi- tions cator 1.
