Notes: 1)

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. (Example of sensing objects)Æ Can wrapped by clear film

The sensing range and sensing object for the retroreflective type sensor is specified for the RF-230 reflector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 0.1m away.

The sensing range of the diffuse reflective type sensor is specified for white nonglossy paper (200 200mm).

If slit masks (optional) are fitted, an object as small as 3 6mm can be detected.

In case the sensor is to be used at an ambient temperature of —15…C, or less, please contact our office.

Make sure to carry out wiring in the power supply off condition. Take care that wrong wiring will damage the sensor. Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground. Do not use during the initial transient time (50ms) after the power supply is switched on. In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Extension up to total 100m, or less, is possible with 0.3mm2, or more, cable. When connecting an inductive load, such as a DC relay, connect a surge absorber as shown in the right figure. Take care that the sensor is not directly exposed to fluorescent light from a rapidstarter lamp or a high frequency lighting device, as it may affect the sensing performance. This sensor is suitable for indoor use only. Avoid dust, dirt, and steam. Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.

Placing 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 determine the range of the light received condition with the help of the operation indicator. Then, set the emitter at the center of this range. Similarly, adjust for up, down, left and right angular movement of the emitter. Further, perform the angular adjustment for the receiver also. Check that the stability indicator lights up.

Retroreflective type sensor

Placing the sensor and the reflector face to face along a straight line, move the reflector in the up, down, left and right directions, in order to determine the range of the light received condition with the help of the operation indicator. Then, set the reflector at the center of this range. Similarly, adjust for up, down, left and right angular movement of the reflector. Further, perform the angular adjustment for the sensor also. Check that the stability indicator lights up.

As light is polarized by a transparent film or membrane, NX5-PRVM5 may not detect an object covered or wrapped by transparent film. In that case, take the following steps.

(Example of sensing objects)

•

Can wrapped by clear film

•

Aluminum sheet covered by plastic film

•

Gold or silver color (glossy) labels or wrapping paper

(Steps)

•

Tilt the sensor with respect to the sensing object upon fitting.

•

Reduce the sensitivity.

•

Increase the distance between the sensor and the sensing object.

With the slit mask, the sensor can detect an object as small as 3 6mm. However, the sensing range is reduced when the slit mask is mounted.

How to mount

Fit the C portion of the slit mask in the groove A

Groove B

of the main body case. Then press the slit mask against the main body to fit the slit mask hook D portion in the groove B of the main body case.

Groove A

How to remove

Insert a ‘minus’ screwdriver into the E portion of the slit mask.

Slit mask

Lift the E portion up to remove the slit mask from the main body case.

By mounting interference prevention filters, two sets of NX5-M10R can be mounted close together. 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.

Note: The filters cannot be used for NX5-M30 .

Fitted with

PF-NX5-H

Fitted with

PF-NX5-V

If interference occurs when using NX5-M10R , use the optional interference filters (PF-NX5- ) to mount two sensors closely. [For details, refer to INTERFERENCE PREVENTION FILTER (OPTIONAL).]

In case interference occurs when NX5-M10R , without interference prevention filters, or NX5-M30 are mounted closely, we recommend that the emitter and the receiver are placed alternatively at a distance, as given below. Further, if interference occurs even when the specified distance is kept, place light barriers, etc.

Example:

Emitter

Keep sufficient distance

: 1m approx. or more (for 10m setting distance)

2.5m approx. or more (for 30m setting distance)

Please take care of the following points when detecting materials having a gloss. Make L, shown in the diagram, sufficiently long. Install at an angle of 10 to 30 degrees to the sensing object. The retroreflective type sensor with polarizing filters, NX5-PRVM5 , does not need such adjustment.
