T18 Sensors — dc-Voltage Series
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
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.
Adjustments Non-polarized retro and diffuse models (only) have a single-turn rear-panel Sensitivity control (turn clockwise to increase
gain).
Indicators Two LEDs (Green and Yellow)
Green ON steady: power to sensor is ON
Green flashing: output is overloaded
Yellow ON steady: N.O. output is conducting
Yellow 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') or 9 m (30') 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)
