12V to 24V DC 15m Battery powered safety beam Infrared Sensor Photo Eye Photocells infrared photocells door gate opener motor Used for automatic slide door, automatic Gate Door, coil door , garage door windows barrier etc. Feature Receiver and Transmitter Consists of a transmitter and a receiver, and the integrated amplifier can produce infrared beam. Anti-interference Narrow infrared beam (I or II) can avoid interruption by external light Detection distance Even installed at low height(20-40cm from the floor), the detecting distance can also be guaranteed(5-15meters). self-detecting function The beam produced by MICROCELL provides a self-detecting function for the sliding doors. Once the self-detecting beam is interrupted, the door will stop closing and reverse rapidly to the utmost width. The door will open until the detecting beam is resumed. When the door completely closes, the detecting beam becomes invalid. Installation: The best Install height should bia in 20 cm.Install distance to be no smaller than 2 meters.lnstall shouldmake red outside the protection equip perpendicularity to place,and is on-line at same levelInstall should Install first to recelve part. Install blast off part again .When together at always line,receive the OFF light in the machine In order to put out, then fix,connect the line to Install completion namely. Technical Specification Rotation through 180* Rotation through 180* llows the alignment of the photocells irespectiveof the way they are fixed to the base Attention: Because this product shoot power compare big,so when shoot machine with receive the machinedistance too near hour will appear have no the phenomenon of the reaction, at this time should drawback them one meter at least behind again try.
