1 SERIES Compact Multi-voltage Photoelectric Multi-voltage Interference prevention Multi-voltage The series can operate a to 2 V AC or to 2 V DC, which makes it suitable for supply voltages all over the world. Compact size Direct hook-up to an AC power supply No need to arrange a DC power supply. 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 ong sensing range Most suitable for conveyor lines and parking lot applications. Thru-beam Retroreflective Diffuse reflective Easy alignment m 32. ft (Red ED) 3 m 9.2 ft (Infrared ED) m 1. ft (Red ED with polarizing filters) 7 m 22.9 ft (Infrared ED) 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. Power Supply Built-in Multi-voltage photoelectric sensor usable worldwide 7 mm 27.9 in (Infrared ED) High reliability Conforming to ow Voltage and EMC Directive 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 Interference prevention Two sensors operate quite normally even if mounted close together. Excluding the 3 m 9.2 ft thrubeam type sensor m 32. ft thru-beam type Interference prevention filters Retroreflective & Diffuse reflective type ight received condition is visually confirmed by the bright operation indicator. Interference prevention filters are available. (Optional) Incorporate automatic interference prevention function.

Interference prevention filter (Exclusively for -MR ) Use the interference prevention filters (optional) when two units of thru-beam type sensors are mounted close together. Fitted with PF--H Fitted with PF--V 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 -M3A or -M3B.
