1 NX SERIES Compact Multi-voltage Photoelectric Power Supply Built-in Multi-voltage photoelectric sensor usable worldwide Conforming to ow Voltage and EMC Directive Multi-voltage The NX series can operate at 2 to 2 V AC or to 2 V DC, which makes it suitable for supply voltages all over the world. Direct hook-up to an AC power supply ong sensing range Most suitable for conveyor lines and parking lot applications. Thru-beam Retroreflective Diffuse reflective m 32. ft (Red ED) 3 m 9. ft (Infrared ED) m 1. ft (Red ED with polarizing filters) 7 m 22.9 ft (Infrared ED) 7 mm 27.9 in (Infrared ED) High reliability It has IP protection. Moderate dust or water splashes do not affect it. The new N2 hermetically sealed output relay significantly increases its reliability. N2 hermetically sealed relay eliminates worries about bad contact No need to arrange a DC power supply. Compact size Despite being multi-voltage, it has a depth of just 3 mm 1.37 in. (W1 H2 D3 mm W.79 H2.1 D1.37 in) Conventional model Compared to the conventional model Depth: 1/2 Width: 2/3 Volume: 1/3 Easy alignment The m 32. ft thru-beam type sensor and the m 1. ft retroreflective type sensor incorporate a red ED beam source. Beam alignment can be attained by visually checking the emitted beam. Interference prevention Two sensors operate quite normally even if mounted close together. Excluding the 3 m 9. ft thrubeam type sensor m 32. ft thru-beam type Interference prevention filters Retroreflective & Diffuse reflective type NX Interference prevention filters are available.

7 NX PRECAUTIS FOR PROPER USE Retroreflective type sensor (NX-RM7 ) Please take care of the following points when detecting materials having a gloss. 1 Make, shown in the diagram, sufficiently long. 2 Install at an angle of to 3 degrees to the sensing object. m NX-PRVM does not need the above adjustment. Make sufficiently long Sensing object to 3 Glossy surface Retroreflective type sensor with polarizing filters (NX-PRVM ) If a shiny object is covered or wrapped with a transparent film, such as those described below, the retroreflective type sensor with polarizing filters may not be able to detect it. In that case, follow the steps 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 Steps Tilt the sensor with respect to the sensing object while fitting. Reduce the sensitivity. Increase the distance between the sensor and the sensing object.
