  • Available in opposed, polarized retroreflective and fixed-field sensing modes
  • Marginal gain indicator with alarm output
  • Dual-LED multi-function indicators for monitoring sensor performance

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)
Polarized Retroreflective:30 mA (exclusive of load)
Fixed-field:35 mA (exclusive of load)
RangeOpposed:20 m
Polarized Retroreflective:2 m, range is specified using one model BRT-3 retroreflector
Fixed-field:0-25, 0-50 or 0-100 mm cutoff, depending on models
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output Rating150 mA max. (each); the total load may not exceed 150 mA OFF-state leakage:less than 1 µA @ 30V dc
ON-state saturation voltage:less 1V @ 10 mA dc; less than 1.5V @ 150 mA dc
Output ConfigurationSensing Output:PNP (current sourcing), light operate
Alarm Output:PNP (current sourcing), normally open and conducts whenever the sensor's excess gain drops to 1-1.5x in light condition
Output Protection CircuitryProtected against false pulse on power-up and continuous overload or short-circuit of outputs
Output Response TimeResponse time is independent of signal strength Opposed:3 millisecond ON; 1.5 milliseconds OFF
Polarized Retroreflective and Fixed-field:3 milliseconds ON/OFF
Delay at Power-up100 milliseconds; outputs do not conduct during this time.
RepeatabilityRepeatability is independent of signal strength Opposed:375 microseconds
Polarized Retroreflective and Fixed-field:750 microseconds
Indicators2 LED Indicators:Green and Yellow
Green ON steady:power to sensor is ON
Green flashing:output is overloaded
Yellow ON steady:normally open output is conducting
Yellow flashing:marginal excess gain (1-1.5x) in light condition
ConstructionThermoplastic polyester housing with polycarbonate or acrylic lenses. One jam nut is included with each sensor.
Environmental RatingLeakproof design is rated NEMA 6P; IEC IP67
Connections4-pin Euro-style quick-disconnect fitting. QD cables are ordered separately.
Operating ConditionsTemperature:-40° to +70° C
Relative humidity:90% @ 50° C (non-condensing)
Vibration and Mechanical ShockAll models meet Mil. Std. 202F requirements. Method 201A (Vibration; frequency 10 to 60 Hz, max., double amplitude 0.06-inch acceleration 10G). Method 213B conditions H&I (Shock: 75G with unit operating; 100G for non-operation)
