Cautions

●This product has been developed / produced for industrial use only.
●Always turn the power off before performing wiring.
●Connect each other's synchronization wires (Orange and Violet wires and its shields also) of
the projector and detector. Do not let them contact with the other wires.
●Verify voltage fluctuation so that it should not exceed the rated value.
●When a switching regulator is used for the power source of
the sensor, make sure to ground the frame ground (F.G.)
terminal to an actual ground.
●If any device that may cause noise (switching regulator,
inverter motor, etc.) is used near the sensor, make sure to
ground the frame ground (F.G.) to an actual ground.
●Use sensors under a stable condition to be obtained after
more than 10 minutes from power supply.
●Cable is extendable up to 50m by using 0.3mm
wire, expect for the sync, (Orange and Violet).
Use shielded cord for extension of the analog voltage
output cord (White). In case of using this product as a
CE marking conformity product, cable extension of
the power wire and I/O wire must be within 30m.
●Do not use the sensor where there is excessive vapor,
dust or corrosive gas, or in the situation where they
could be exposed directly to water.
●Do not run sensor cables parallel to high-voltage lines or
power lines, nor put them together in the same raceway.
Doing so may cause malfunctions from inductive interference.
●LA-511 employs a line-bypass capacitor system to enhance electrical noise resistance. If there
is any equipment near the sensor such as supersonic welding machine which produces a high
frequency noise, and in addition, if sensor mounting framework is electrically conductive, an
insulation is required between the sensor and the framework.
Beside, do not use a power source with an auto-trans former as it may result in a failure to
danger if any fault happen at internal circuit.
