3-2 Mounting interval (thru-beam type NX5-M□)
●In case mounting two sets or more of the this product close together, mount them as
drawing left indicates (typical example)
●Find out the operating point ℓon the parallel deviation diagram for the setting distance L.
Separate sensors by 2 × ℓor more.
<Installation interval for NX5-M10R□>
In case using at sensing distance (L1) 10m, the opera-
tion point (ℓ1) is approx. 444mm according to diagram
left.
The installation interval is
Approx. 444mm × 2 = 888mm
Thus, install another NX5-M10R□to 888mm or more
away.
<Installation interval for NX5-M30□>
In case using at sensing distance (L2) 30m, the opera-
tion point (ℓ2) is approx. 1,200mm according to dia-
gram left.
The installation interval is
Approx. 1,200mm × 2 = 2,400mm
Thus, install another NX5-M30□to 2,400mm or more
away.

3-3 Long sensing range retroreflective type sensor
(NX5-RM7□)
●Please take care of the following points when detecting materials having a gloss
with retroreflective type sensor (NX5-RM7□).
1. Make L, shown in the diagram, sufficiently long. (Note)
2. Install at an angle of 10 to 30 degrees to the sensing object.
Note: In case the distance between the sensor and the sensing object is short, the re-
flected light from the sensing object may be detected.
●Retroreflective type with polarizing filter (NX5-PRVM5□)does not need the above
adjustment.
LThe distance L should be as long possible.

1. Place the emitter and the receiver face to face
along a straight line, move the emitter in the up,
down, left and right directions, in order to deter-
mine the range of the light received condition with
the help of the operation indicator (red). Then, set
the emitter at the center of this range.
2. Similarly, adjust for up, down, left and right
angular movement of the emitter.
3. Further, perform the angular adjustment for the
receiver also.
4. Check that the stability indicator (green) lights up.

5-2 Sensitivity adjustment
Step
1. Turn the sensitivity adjuster fully counterclockwise to the
minimum sensitivity position (MIN.)
2. In sensing object present condition, turn the sensitivity ad-
juster slowly clockwise and confirm the point Awhere the
sensor enters the “Light” state operation.
3. In non-sensing object present condition, turn the sensitivity
adjuster further clockwise until the sensor enters the “Light”
state operation and then bring it back to confirm point B
where the sensor just returns to the “Dark” state operation.
If the sensor does not enter the “Light” state operation
even when the sensitivity adjuster is turned fully clock-
wise, the position is point B.
4. The position at the middle of points Aand Bis the optimum
sensing position.
Note: Use the accessory adjusting screwdriver to turn the adjuster slowly. Turning with excessive strength will cause
damage to the adjuster.

Automatic interference prevention function
●The retroreflective type NX5-PRVM5□/ NX5-RM7□and the diffuse reflective type
NX5-D700□incorporate an automatic interference prevention function, so that two sen-
sors can be mounted closely. (Thru-beam type NX5-M10R / NX5-M30□does not incor-
porate the automatic interference prevention function.)
Note: If
NX5-D700□are mounted facing each other, they should be angled so as not to receive the beam from
the opposing sensor or to detect its front face.
Not good Good

14
7. Stability indicator
●The stability indicator (green) lights up when the incident light intensity has sufficient
margin with respect to the operation level.
Incident light intensity level is such that the stability indicator light up, stable sensing can
be done without the light received operation and the light interrupted operation being
affected by a change in ambient temperature or supply voltage.
Use the staility indicator in the condition below
• Adjusting the light axes
• Checking dirt of the sensor

15
8. Retroreflective type sensor with
polarizing filter (NX5-PRVM5□)
If a shiny object is covered or wrapped with a transparent film, such as those described
below, the retroreflective type sensor with polarizing filters NX5-PRVM5□may not be
able to detect it. In that case, take the following measures given below.
<Example of sensing objects>
• Can wrapped by clear film
• Aluminum sheet covered by plastic film
• Gold or silver color (specular) label or wrapping paper
<Measures>
• Tilt the sensor with respect to the sensing object while fitting.
• Reduce the sensitivity.
• Increase the distance between the sensor and the sensing object.

9-2 Interference prevention filter
(exclusively for thru-beam type sensor NX5-M10R□)
●By mounting interference prevention filters PF-NX5-□, two sets of NX5-M10R□can be
mounted close together.
However, the sensing range is reduced when the interference prevention is mounted.
●The filters can be mounted by the same method as for the slit masks.
●There are two types of interference prevention filters. The two sets of thru-beam type
sensors should be fitted with different types of interference prevention filters.
●The interference prevention does not work even if the filters are mounted for emitters
only, receivers only or the same model No. of the interference prevention filters are
mounted on both the sets of the sensor.

Notes: 1) The model No. with suffix “P” shown on the label affixed to the thru-beam type sensor is the emitter, “D”
shown on the label is the receiver.
(e.g.) Thru-beam type sensor emitter: NX5-M10RP, Thru-beam type sensor receiver: NX5-M10RAD
2) The retroreflective type sensor with polarizing filters may not stably detect specular or glossy objects
through transparent film since light is polarized by the transparent film.
3) The sensing range and sensing object for the retroreflective type sensor is specified for the RF-230 re-
flector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect
an object less than 0.1m away.
4) The sensing range and hysteresis of the diffuse reflective type sensor and narrow-view reflective type
sensor are specified for white non-glossy paper (200 × 200mm) as the object.
5) If slit masks (optional) are fitted, an object as small as 3 × 6mm can be detected.
6) Make sure to confirm detection with an actual sensor before use.
7) By mounting optional interference prevention filter PF-NX5-□, two sensors can be mounted closely.
8) In case the sensor is to be used at an ambient temperature of -15
