Transparent glass sensing type / Micro spot type
● Stable sensing for transparent object(LCD, PDP, glass etc)
by BJG30-DDT
● Easy to check sensing location with visible micro spot(BJN Series)
● Detects tiny objects (min. sensing target Ø0.2mm copper wire)
Commonness
● Compact size: W20×H32×L10.6mm
● Protection structure IP65(IEC standard)
● Light ON/Dark ON selectable by VR(Except BJG30-DDT)

1. Place the emitter and the
receiver facing each other and
supply the power.
2. After adjusting the position of
the emitter and the receiver
and check their stable
indicating range, mount them
in the middle of the range.
3. After mounting this unit, check the operation of the sensor
and lighting of the stability indicator in both status. (None
or sensing target status)
※When the sensing target is translucent or small(under
sensing target of ‘ Specifications’), it may not be
detected by the sensor because the light can penetrate it.

1.Place the sensor and the reflector
facing each other and supply the
power.
2.After adjusting the position of the
sensor and reflector and check
their stable indicating range,
mount them in the middle of the
range. (None or sensing target
status)
3.After mounting this unit, check the operation of the
sensor and in both status. (None or sensing target status)
After place a sensing target, adjust
the sensor to up or down, right or
left.
Then, fix the sensor in the center
of position where the stability is
operating.
※No sensitivity adjustment function available for BJG30-
DDT models.
※Set the sensitivity to operate in stable light ON area and
the reliability for the environment (temperature, voltage,
dust etc) is increased. In unstable light ON area, be sure
that the variation of environment.
※Do not apply excessive force on the adjustment VR, it
may be broken.
※Mount the sensor slanted at an angle ranged 0 to 15˚ shown
above as [Figure 2] for stable detection to detect as shown
in [Figure 1].

(A) Turn the adjustment VR to the right of
min. and check position(A) where the
operation indicator is turned ON in “Light
ON status”.

(A) (C)
(B)
Turn the adjustment VR more to the right
of position(A), check position(B) where
the operation indicator is turned ON. And
turn the adjustment VR to the left, check
position(C) where the operation indicator is
turned OFF in “Light OFF status”.
※If the operation indicator is not turned ON
although the adjustment VR is turned to
the max. position, the max. position is (C).

Optimal
sensitivity
(A) (C)
Set the adjustment VR at the center of (A)
and (C). To set the optimum sensitivity,
check the operation and lighting of
stability indicator with sensing target or
without it. If the stability indicator is not
turned ON, please check the sensing
method again because sensitivity is
unstable.
