Specifications
Supply Voltage and Current
10 to 30V dc (10% max. ripple); supply current (exclusive of load
current):
Emitters, Non-Polarized, Retro, Diffuse: 25 mA
Receivers: 20 mA
Polarized Retroreflective: 30 mA
Fixed-Field: 35 mA
Supply Protection Circuitry
Protected against reverse polarity and transient voltages
Indicators
Two LEDs (Green and Yellow)
Green ON solid: power to sensor is ON
Green flashing: output is overloaded
Amber ON solid: N.O. output is conducting
Amber flashing: excess gain marginal (1 to 1.5x) in light condition
Construction
PBT polyester housing; polycarbonate (opposed-mode) or acrylic lens
Environmental Rating
Leakproof design rated NEMA 6P, DIN 40050 (IP69K)
Connections
2 m (6.5 ft) or 9 m (30 ft) attached cable or 4-pin Euro-style quick-
disconnect fitting
Operating Conditions
Temperature: –40 to +70 °C (–40 to +158 °F)
Maximum relative humidity: 90% at 50 °C (non-condensing)
Vibration and Mechanical Shock
All models meet Mil. Std. 202F requirements. Method 201A (Vibration;
frequency 10 to 60 Hz, max., double amplitude 0.06" acceleration
10G). Method 213B conditions H&I (Shock: 75G with unit operating;
100G for non-operation)
Output Configuration
SPDT solid-state dc switch; NPN (current sinking) or PNP (current
sourcing), depending on model
Light Operate: N.O. output conducts when sensor sees its own (or the
emitter’s) modulated light
Dark Operate: N.C. output conducts when the sensor sees dark; the
N.C. (normally closed) output may be wired as a normally open
marginal signal alarm output, depending upon hookup to power supply
Output Rating
150 mA maximum (each) in standard hookup. When wired for alarm
output, the total load may not exceed 150 mA.
OFF-state leakage current: < 1 microamp @ 30V dc
ON-state saturation voltage: < 1V @ 10 mA dc; < 1.5V @ 150 mA dc
Output Protection Circuitry
Protected against false pulse on power-up and continuous overload or
short circuit of outputs
Output Response Time
Opposed mode: 3 ms ON, 1.5 ms OFF
Retro, Fixed-Field and Diffuse: 3 ms ON and OFF
NOTE: 100 ms delay on power-up; outputs do not conduct during this
time.
Repeatability
Opposed mode: 375 μs
Retro, Fixed-Field and Diffuse: 750 μs
Repeatability and response are independent of signal strength.
