S18 Sensors – dc-Voltage Series
WARRANTY:  Banner Engineering Corp. warrants its products to be free from defects for 
one year. Banner Engineering Corp. will repair or replace, free of charge, any product of its 
manufacture found to be defective at the time it is returned to the factory during the warranty 
period. This warranty does not cover damage or liability for the improper application of 
Banner products. This warranty is in lieu of any other warranty either expressed or implied.
P/N 116159
Supply Voltage and Current (exclusive of load 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; Choose NPN (current sinking) or PNP (current 
sourcing) models
  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 (U.S. patent 5087838) 
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 at 10 mA dc; < 1.5V at 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.
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)
