Product Specifications

Supply Voltage and Current10 to 30V dc (10% max. ripple) Opposed Emitters:25 mA (exclusive of load)
Opposed Receivers:20 mA (exclusive of load)
RangeOpposed:15 m
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output ConfigurationSolid-state complementary (SPDT) dc switch: NPN (current sinking) or PNP (current sourcing), depending on model. The dark operate (DO) output may be wired as a normally open marginal signal alarm output, depending upon hookup to the power supply.
Output Rating100 mA max. (each) in standard hookup. When wired for alarm output, the total load may not exceed 100 mA OFF-state leakage current::less than 1 µA @ 30V dc
ON-state saturation voltage:less than 1V @ 10 mA dc; less than 1.5V @ 150 mA dc
Output Protection CircuitryProtected against false pulse on power-up and continuous overload or short circuit of outputs
Output Response Time3 milliseconds ON; 1.5 milliseconds OFF; response time is independent of signal strength.
Delay at Power-up100 milliseconds; outputs do not conduct during this time.
Repeatability375 microseconds; repeatability is independent of signal strength.
Indicators2 LED Indicators:Green and Yellow
Green ON steady:power to sensor is ON
Green flashing:output is overloaded
Yellow ON steady:light-operate (LO) output is energized
Yellow flashing:marginal excess gain (1-1.5x) in light condition, LO output is energized
ConstructionThermoplastic polyester housing with polycarbonate or acrylic lenses. Two jam nuts are included with each sensor.
Environmental RatingLeakproof design rated NEMA 6P (IEC IP67)
Connections2 m or 9 m attached cable, or 4-pin Pico-style quick-disconnect fitting. QD cables are ordered separately.
Operating ConditionsTemperature:-40° to +70° C
