** For 9 m cable, add suffix W/30 to the 2 m model number (example, SM312F W/30). A model with a QD requires a mating cable (see page 380).

MINI-BEAM

Supply Voltage and Current

10 to 30V dc (10% max. ripple) at less than 25 mA (exclusive of load)

Supply Protection Circuitry

Protected against reverse polarity and transient voltages

Output Configuration

Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor; light operate (LO) or

dark operate (DO) selectable.

Output Rating

150 mA max. each output at 25° C, derated to 100 mA at 70° C (derate

≈ 1 mA per ° C)

Off-state leakage current: less than 1 µA

Output saturation voltage (PNP output): less than 1 volt at 10 mA and less than 2 volts at 150 mA

Output saturation voltage (NPN output): less than 200 millivolts at 10 mA and less than 1 volt at 150 mA

Output Protection Circuitry

Protected against false pulse on power-up and continuous overload or short-circuit of outputs

Output Response Time

Sensors will respond to either a “light” or a “dark” signal of 1 millisecond or longer duration, 500 Hz max.

0.3 millisecond response modification is available. See note below

NOTE: 100 millisecond delay on power-up: outputs do not conduct during this time.

Repeatability

Opposed: 0.14 milliseconds; Non-Polarized and Polarized Retroreflective, Diffuse, Convergent, Glass and

Plastic Fiber Optic: 0.3 milliseconds. Response time and repeatability specifications are independent of signal strength.

Adjustments

LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment potentiometer

(clutched at both ends of travel). Both controls are located on rear panel of sensor and protected by a gasketed,

clear acrylic cover.

Indicators

Alignment Indicating Device system (AID) lights a rear-panel mounted red LED indicator whenever the sensor sees

a “light” condition, with a superimposed pulse rate proportional to the light signal strength (the stronger the signal,

the faster the pulse rate).

Construction

Reinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses, and stainless steel screws.

Environmental Rating

Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67

Connections

PVC-jacketed 4-conductor 2 m or 9 m cables, or 4-pin Euro-style quick-disconnect (QD) fitting are available. QD

cables are ordered separately. See page 380.

Operating Conditions

Temperature: -20° to +70° C

Relative humidity: 90% at 50° C (non-condensing)

Emitters: DC03 (p. 476)
