SM312F
Self-contained DC-operated Sensors for use with Banner Glass Fiber Optics
Printed in USA 05/01 P/N 03368 rev. E
• Compact, modulated, self-contained infrared fiber optic
sensors for 10-30V dc operation
• Useable in opposed, retroreflective, and diffuse fiberoptic
modes with Banner glass fiber optic assemblies
• Switch-selectable for light operate or dark operate
• Includes Banner’s exclusive AID™ alignment system;
US patent number 4356393
• Highly-repeatable 1 millisecond response
• Both sourcing and sinking outputs (150 mA max. each);
continuous overload and short-circuit protected
NOTES:
i) 9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SM312F W/30).
ii) A 150 mm (6") long pigtail cable with attached QD connector is available by adding suffix “QDP” to the model number of any
MINI-BEAM sensor (e.g., SM312FQDP). See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information.
iv) May be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers
(e.g., SM312FMHS). This modification reduces sensing range (and excess gain).
