Datasensor SMall series offers a complete line of subminiature amplified photoelectric sensors, ideal for mounting in reduced spaces or in presence of particular mechanical obstacles. The extremely compact dimensions and wide detection field of all modes suit most of the applications on automatic machinery for packaging, assembling, printing as well as in automatic distribution and vending machines. Datalogic series offers many different optic functions including 1.5 m retroreflex, 1 m polarised retroreflex, and 2 m through beam. The 15 mm, 20 mm, 30 mm and 50 mm fixed focus proximity models represent a valid alternative to fiber-optic systems and can be used to detect objects with small profiles and poorly reflective materials. All models of the subminiature SMall series have visible red emission facilitating alignment, cable connection and are available in the NPN or PNP versions with NO-NC double output. The plastic housing guarantees an IP67 protection degree.
