SM30 High-Power Series


  • Features EZ-BEAM technology, with specially designed optics and electronics for reliable sensing without adjustments
  • Offers choice of 30 mm plastic or stainless-steel threaded barrel, depending on application
  • Operates in opposed mode with very high excess gain
  • Offers high-power sensing with a range of 200 m
  • Available in models with standard 10 to 30V dc with Bi-Modal NPN/PNP outputs or 24 to 240V ac with SPST solid-state output
  • Uses positive sealing to eliminate even capillary leakage; lens is quad-ring sealed
  • Exceeds IEC IP67 (NEMA 6P) ratings; ideal in equipment washdown environments
  • Includes advanced diagnostics to warn of marginal sensing conditions or output overload (dc models)
  • Offers three modulation frequencies to minimize optical crosstalk potential between adjacent sensor pairs

Product Specifications

Supply Voltage and CurrentEmitters:10 to 30V dc (10% max. ripple) @ 20 mA or 12 to 240V ac (50/60 Hz)
DC Receivers:10 to 30V dc (10% max. ripple) @ 10 mA (exclusive of load)
AC Recievers:24 to 240V ac (50/60 Hz)
Range150 m (500 feet)
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output ConfigurationDC Receivers:
BiModal Output (NPN sinking or PNP sourcing):Selection of sourcing or sinking configuration depends upon receiver's power supply hookup polarity. Once wired, the unit performs as a SPDT offering complementary outputs.
AC Receivers:
SPST solid-state ac switch:Light operate (LO) or dark operate (DO), depending on model
Output RatingDC Receivers:250 mA max. (continuous)
Output saturation voltage (PNP & NPN configuration):less than 1V @ 10 mA; less than 2V @ 250 mA
OFF-state leakage current:less than 10 µA
AC models:Max. steady-state load capability is 500 mA
Inrush capability:10 A for 1 second, non-repetitive
OFF-state leakage current:less than 1.7 mA rms
ON-state voltage drop:less than 3.5V rms across a 500 mA load; less than 5V rms across a 15 mA load
Output Protection CircuitryOutputs of dc receivers are short circuit protected
Output Response Time10 milliseconds ON/OFF
RepeatabilityFrequency A Units:1 millisecond
Frequency B Units:1.5 milliseconds
Frequency C Units:2.3 milliseconds
IndicatorsInternal red LED, visible through the lens or from side of the sensor. Emitters, 1 LED Indicator:
Red ON steady:power to sensor is ON
DC Receiver, 1 LED Indicator:
Red:Lights whenever receiver sees its modulated light source
AC Receiver, 1 LED Indicator:
Red:Lights whenever receiver’s output is conducting
ConstructionFully epoxy-encapsulated tubular threaded housing, positive sealed at both ends, quad-ring sealed acrylic lens Plastic models:30 mm diameter thermoplastic polyester housing and jam nuts
Stainless-Steel models:30 mm diameter 303 stainless-steel housing and jam nuts
Environmental RatingExceeds NEMA 6P; IEC IP67 standards
Connections2 m or 9 m attached cable, or Mini-style quick-disconnect fitting. QD cables are ordered separately.
