SMA912DQD

The SMA912DQD is a rugged self-contained Photoelectric Sensor designed for especially demanding industrial applications where economy, performance and durability are important. VALU-BEAMs are built in a variety of operating voltages (both DC and AC) and output types (solid state and electromechanical relay). SMI912 series are intrinsically safe sensors. Powerful, modulated LED light sources give VALU-BEAM sensors greater sensing range than competitive units and a high degree of immunity to ambient light. All models are totally epoxy encapsulated and housed in moulded VALOX® housings for the ultimate in shock, vibration, moisture and corrosion resistance. All VALU-BEAM sensors conform to NEMA standards 1, 2, 3, 3S, 4, 4X, 12 and 13.
