SM312CV and SM312CV2
Self-contained DC-operated Convergent Mode Sensors
Printed in USA 05/01 P/N 03365 rev. D
• Compact, modulated, self-contained convergent mode sensors for
10-30V dc operation
• Produces a precise 1.3 mm (0.05") diameter sensing spot at a
focus point 16 mm (0.65") from the lens surface (model SM312CV)
or a 3.0 mm (0.12") sensing spot at 43 mm (1.70") focus (model
SM312CV2)
• Switch-selectable for light operate or dark operate
• Includes Banner’s exclusive AID™ alignment system*
• Highly repeatable 1 millisecond response
• Both sourcing and sinking outputs (150 mA max. each); continuous
overload and short-circuit protected
• Rugged, epoxy-encapsulated construction: meets NEMA standards
1, 2, 3, 3S, 4, 4X, 6, 12 and 13; IEC IP67
• Physically and electrically interchangeable with 18 mm barrel-type
photoelectrics
*US patent number 4356393
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. - SM312CV 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. - SM312CVQDP). See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 8 for more information.
iv) May be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers (e.g. - SM312CVMHS). This
modification reduces sensing range (and excess gain).
