SM2A312F
Self-contained AC-operated Sensors for use with Banner Glass Fiber Optics
Printed in USA P/N 03375L7G
• Compact, modulated, self-contained infrared fiber optic
sensors for 24-240V ac 2-wire operation
• Useable in opposed, retroreflective, and diffuse fiberoptic
modes with Banner glass fiber optic assemblies
• Switch-selectable for light operate or dark operate
• 8 millisecond response
• SPST SCR solid-state output switches up to 300 mA; low
leakage current and saturation voltage
• Rugged, epoxy-encapsulated construction: meets NEMA
standards 1, 2, 3, 3S, 4, 4X, 12 and 13; IEC IP67
Infrared, 880 nm
For Standard MINI-BEAMs:
i) 9 m (30 ft) cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g. - SM2A312F W/30).
ii) A 150 mm (6 in.) long pigtail cable with attached QD connector is available by adding suffix “QDP” to the model number of any
MINI-BEAM sensor (e.g. - SM2A312FQDP). See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information.
