Pepperl+fuchs offers photoelectric sensor - the series 31. With a dimension of 62 x 35 x 18 mm, it is the smallest in its class and yet it has sensing ranges that exceeds those of the competition. This is despite the sensor having the smallest depth of 35 mm. [in optical sensors s one of the ways to achieve better optical performance is to have larger depths]. This small size allows it to be installed in tight and compact spaces. The series 31 finds applications such as closing edge monitoring of doors and gates and object detection and tracking in material handling. The range includes single path light beam switches, reflex light beam switches [with and without polarization filters], direct detection light scanners. The photoelectric sensors of the series 31 offer unbeatable price/performance ratio. Compact ip67 plastic housing with three mounting holes guarantees easy interchangeability and compatibility with existing mounting systems. Coloured rhombus ind9cates the function principle, thus mistakes are excluded. Highly visible led displays are eleverly positioned at the housing edges for largest view angles. Universal voltage units with spdt relay output give nc and no outputs.
