Maximum sensing height 540 mm 21.260 in (28 beam channels)

Slim body of just 13 mm 0.512 in thick

The slim-bodied NA2-N series fits right in your equipment, since it is only 13 mm 0.512 in thick and 30 mm 1.181 in wide. It dose not get in the way of your access to the machine.

6 types of sensing height

In addition to the conventional 12, 16, and 20 beam channel types, this new lineup includes 8, 24, and 28 beam channel types. A wide model variation is provided with sensing heights from 540 mm 21.260 in (28 beam channels) to 140 mm 5.512 in (8 beam channels).

Globally usable

It conforms to the EMC Directive and obtains the UL Recognition. Products that has obtained the Korea’s S-mark certification are available as well.
Moreover, PNP output type which is much in demand in Europe is also available.

Clearly visible wide job indicator

Both the receiver and the emitter feature job indicators, 102 mm 4.016 in wide, with red bright LEDs.
When the sensing output and the job indicator input are connected, the job indicator can be used as a large operation indicator.

Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.
2) Obtain the current consumption from the following equation.
Current consumption = Power consumption ÷ Supply voltage
(e.g.) In case of NA2-N8 (when job indicator lights up)
When the supply voltage is 12 V, the current consumption of the emitter is: 0.7 W ÷ 12 V ≈ 0.058 A = 58 mA.
3) Peak emission wavelength has been changed from production in March, 2017.

Note :	The model No. with “P” shown on the label affixed to the product is the emitter, “D” shown on the label is the receiver.

5 m 16.404 ft cable length type

5 m 16.404 ft cable length type (standard: 3 m 9.843 ft ) is also availble for NPN output type.
When ordering this type, suffix “-C5” to the model No.
(e.g.) 5 m 16.404 ft cable length type of NA2-N8 is “NA2-N8-C5”.
