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 ● 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. • When direct soldering to the terminal, use the following guidelines. Soldering Conditions Item Temperature Permissible time Soldering iron 350°C max. 3 s max. Remarks Autotransformer Power source + − Sensor Power source + − Sensor The portion between the base of the terminals and the position 1.5 mm from the terminal base 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. Insulated transformer Cable Extension • When extending the cable, use an extension cable with conductors having a total cross-section area of 0.3 mm2. 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 Background object Sensing conditions Check Background object A Adjuster indicator Adjustment Procedure Setting Background object B Black paper with small reflection factor C B C 1.
