SM312W and SM312DBZ
Self-contained DC-operated Wide-angle Diffuse Mode Proximity Sensors
Printed in USA 05/01 P/N 03564 rev. C
• Compact, modulated, self-contained infrared wide-angle
diffuse proximity mode sensors for 10-30V dc operation
• SM312W wide angle (divergent) diffuse mode sensor,
125 mm (5 in) range; Ideal for close-range sensing of
transparent or translucent objects, or objects with small
profile
• SM312DBZ: wide-angle diffuse mode sensor, 300 mm
(12 in) range
• Both models have clear acrylic opto-element covers to
meet FDA food-processing application requirements
• 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
*US patent number 4356393

*NOTES:
i) 9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SM312DBZ 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., SM312DBZQDP). See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 6 for more information.
iv) May be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers
(e.g., SM312DBZMHS). This modification reduces sensing range (and excess gain).
