Overview

  • Features EZ-BEAM technology, with specially designed optics and electronics for reliable sensing without adjustments
  • Completely epoxy-encapsulated for superior durability, even in harsh sensing environments
  • Features 30 mm plastic threaded barrel
  • Operates in opposed mode with a 60 m range
  • Uses innovative dual-indicator system to take the guesswork out of monitoring sensor performance
  • Available in 10 to 30V dc with NPN or PNP output, or 20-250V ac with SPST solid-state output
  • Includes advanced diagnostics to warn of marginal sensing conditions or output overload (dc models)

Product Specifications

Supply Voltage and CurrentDC models:10 to 30V dc (10% max. ripple)
Emitters:25 mA (exclusive of load)
Receivers:20 mA (exclusive of load)
AC models:20 to 250V ac (50/60 Hz)
Average Current:20 mA
Peak current:200 mA @ 20V ac, 500 mA @ 120V ac, 750 mA @ 250V ac
Range60 m
Supply Protection CircuitryDC models:Protected against reverse polarity and transient voltages
AC models:Protected against transient voltages
Output ConfigurationDC models:
Solid-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.
AC models:
SPST solid-state ac switch; three-wire hookup:Light operate (LO) or dark operate (DO), depending on model
Light operate:Output conducts when the sensor sees its own (or the emitter’s) modulated light
Dark operate:Output conducts when the sensor sees its own (or the emitter’s) modulated light
Output RatingDC models:150 mA max. (each) in standard hookup. When wired for alarm output, the total load may not exceed 150 mA
OFF-state leakage:less than 1 µA @ 30V dc
ON-state saturation voltage:less than 1V @ 10 mA dc; less than 1.5V @ 150 mA dc
AC models:300 mA max. (continious)
Inrush capability:1 A for 20 milliseconds, non-repetitive
OFF-state leakage current:less than 100 µA
ON-state voltage drop:3V @ 300 mA ac; 2V @ 15 mA ac
Output Protection CircuitryDC models:Protected against false pulse on power-up and continuous overload or short circuit of outputs
AC models:Protected against false pulse on power-up
Output Response TimeResponse time is independent of signal strength. DC models:3 milliseconds ON; 1.5 milliseconds OFF
AC models:16 milliseconds ON; 8 milliseconds OFF
Delay at Power-upDC models:100 milliseconds; outputs do not conduct during this time.
AC models:100 milliseconds
RepeatabilityRepeatability is independent of signal strength. DC models:375 microseconds
AC models:2 milliseconds
IndicatorsDC models, 2 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
AC models, 2 LED Indicators:Green and Yellow
Green ON steady:power to sensor is ON
Yellow ON steady:sensor sees light
Yellow flashing:marginal excess gain (1-1.5x) in light condition
ConstructionThermoplastic polyester housing with polycarbonate or acrylic lenses. Two jam nuts are included with each sensor.
Environmental RatingLeakproof design rated NEMA 6P; DIN 40050 (IP69K)
ConnectionsDC models:2 m or 9 m attached cable, or 4-pin Euro-style quick-disconnect fitting. QD cables are ordered separately.
AC models:2 m or 9 m attached cable, or 4 pin Micro-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)
