SMB312S Overview

Self-contained DC-operated Opposed Mode Sensors

MINI-BEAM
®
SM2A312CV and SM2A312CV2
Self-contained AC-operated Convergent Mode Sensors
• Compact, modulated, self-contained convergent mode
sensors for 24-240V ac operation
• Produces a precise 1.3 mm (0.05 in) diameter sensing spot
at a focus point 16 mm (0.65 in) from the lens surface
(model SM2A312CV) or a 3.0 mm (0.12 in) sensing spot at
43 mm (1.70 in) focus (model SM2A312CV2)
• Switch-selectable for light operate or dark operate
• SPST SCR solid-state output switches up to 300mA; low
leakage current and saturation voltage
• Rugged, epoxy-encapsulated construction: meets NEMA
standards 1, 2, 3, 3S, 4, 4X, 12 and 13; IEC IP67
• Physically and electrically interchangeable with 18 mm
barrel-type photoelectrics
Visible red, 650 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. -
SM2A312CV 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. -
SM2A312CVQDP).
See page 5 for more information.
iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information.

Generally speaking, which type of resistor do you choose for a resistor with slightly higher power?
The color ring resistors we usually use have a power of only a quarter watt, and they become very hot when the current is slightly higher, and this is only when the power is on for a few seconds. In g...
