|Supply Voltage and Current||10 to 30V dc (10% max. ripple) @ less than 25 mA (exclusive of load)
|Range||Opposed (long range):30 m
Opposed (short range:3 m
Opposed (clear plastic):0.3 m
Non-polarized Retroreflective:5 m, range is specified using one model BRT-3 retroreflector
Polarized Retroreflective:50 mm to 2 m, range is specified using one model BRT-3 retroreflector
Polarized Retroreflective (extended range):10 mm to 3 m, range is specified using one model BRT-3 retroreflector
Diffuse (long range):380 mm
Diffuse (short range):300 mm
Divergent Diffuse:130 mm
Convergent:16, 43 or 49 mm, depending on model
Plastic and Glass Fiber Optic:Range varies by sensing mode and fiber optics used
|Supply Protection Circuitry||Protected against reverse polarity and transient voltages
|Output Configuration||Bipolar:One NPN (current sinking) and one PNP (current sourcing); light operate (LO) or dark operate (DO) selectable
|Output Rating||150 mA max. each output @ 25° C, derated to 100 mA @ 70° C (derate approximately 1 mA per ° C)
OFF-state leakage current:less than 1 µA
Output saturation voltage:
PNP:less than 1V @ 10 mA and less than 2V @ 150 mA
NPN:less than 200 mV @ 10 mA and less than 1V @ 150 mA
|Output Protection Circuitry||Protected against false pulse on power-up and continuous overload or short circuit of outputs
|Output Response Time||Response time is independent of signal strength. Sensors will respond to either a light or dark signal of 1 millisecond or longer duration, 500 Hz max.
Note:Models may be ordered with 0.3 millisecond ON/OFF by adding suffix MHS to the model number (example, SM312LVMHS). This modification reduces sensing range and excess gain.
|Delay at Power-up||100 milliseconds; outputs do not conduct during this time.
|Repeatability||Repeatability is independent of signal strength.
Non-polarized and Polarized Retroreflective, Diffuse, Convergent, Glass and Plastic Fiber Optic:0.3 milliseconds
|Adjustments||Light/Dark-operate select switch and 15-turn slotted brass screw sensitivity (Gain) 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||NEMA 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 QD. QD cable are ordered separately.
|Operating Conditions||Temperature:-20° to +70° C
Relative humidity:90% @ 50° C (non-condensing)
