UZD6
Series
PRECISE OBJECT DETECTION IN LIMITED AREA
Stable Sensing by Fixed-focus
The UZD6 is less affected by color or
uneveness on the surface of a sensing
object, or a background away from it at
a certain distance.
Compact Size
(W102H302D18mm)
(W.3942H1.1812D.709inch)
No matter to install in a limited space.
Variable OFF-delay Timer
(UZD621 only)
The spot-beam type UZD621 is incor-
porated with the OFF-delay timer.
The variable OFF-delay timer is useful
for detecting a circuit board regardless
of small holes, cutouts or electric parts
on it.
Waterproof
No problem even if water splashes on
the sensor.
Note : Do not expose it to water splash during
operation. If it may so, it detects water drop
on it.
No-corrosive stainless
steel mounting bracket.
Various Applications
In the limited sensing area, the sensor
can detect uneven or perforated
objects.
Visible red spot beam allows easy tar-
getting.
It is suitable for positioning because of
the repeatability of 0.05mm .002inch.

rial and sensing range
[]
Background
The sensor does not detect
even a specular object
100mm or more distant from
it. (with UZD62)
However, the sensor shall be
placed as right opposed to
the specular background.

PRECAUTIONS FOR PROPER USE
These products are not safety sensors
and are not designed or intended to be
used to protect life and prevent bodily
injury or property damage.
Mounting
• With the optional mounting bracket, the tightening torque
should be 0.5 N·m {5.1 kgf·cm} or less.
Others
• The transient time duration is 50ms after power-up.
Timer function (Only for UZD621)
• The variable OFF-delay timer prolongs the output for a cer-
tain period (approx. 0.1 to 1sec.).
It is useful for detecting tiny objects or for using with a PLC
scaning delayingly.
(The timer is always in effect.)
UZD861
(Option)
M3216mm .630inch
screws with washers
Timer adjuster
OFF-delay time becomes longer
if it is turned clockwise.
Operation indicator (Red)
Lights up when the output
is activated.
Stability indicator (Green)
Lights up under the stable Light
condition or the stable Dark condition.
