2 Installation and Wiring
Installation
• Tightening torque for the mounting holes: 0.63 N·m (M3 screw)
• If the detecting object has a mirrored surface, install the sensor in a position where
specular reflection will not penetrate the optical receiver.
Wiring
With the LR-TB Series, you can select the functions of the I/O wires (black and white) from
the combinations shown below during the initial settings.
"3 Initial Settings" (page 3)
Independently isolate any I/O wires that you will not use.
