Compact, rugged photoelectric sensor with visible red sensing beam in all-metal, mechanically robust construction is ideal for conveyors in heavy duty machine environments and IP69K applications.

  • Heavy duty metal (nickel-plated die cast zinc) housing with 18mm threaded barrel mount and integral metal QD
  • Models with 4-wire complementary NPN or PNP, or 3-wire I/O block compatible outputs available
  • Visible red LED models available in opposed, polarized retroreflective, diffuse, and fixed-field (background suppression) modes
  • Infrared models available in fixed-field (background suppression) mode
  • Completely epoxy encapsulated electronics
  • Sensors rated IP69K for resistance to intermittent high pressure washdown
  • Innovative dual indicator systems
  • Fixed-field and diffuse models are immune to fluorescent lights and false outputs from lights beyond the sensing point

Product Specifications

Supply Voltage and Current10 to 30V dc (10% max. ripple within specified limits);

supply current (exclusive of load current):

Emitters: 25 mA

Receivers: 20 mA

Polarized Retroreflective: 20 mA

Diffuse and Fixed-Field: 35 mA
Supply Protection CircuitryProtected against reverse polarity and transient voltages
Output ConfigurationNPN (current sinking) or PNP (current sourcing), depending on model

Light Operate: Output conducts when sensor receives its own (or the emitter’s) modulated light

Dark Operate: Output conducts when sensor does not receive it own (or the emitter's) modulated light
Output Rating150 mA maximum each output at 25°C, derated to 100 mA at 70°C (derate about 1 mA per °C)

OFF-state leakage current: < 1 microamp @ 30V dc

ON-state saturation voltage: < 1V @ 10 mA dc; <1.5V @ 150 mA dc
Output Protection CircuitryProtected against false pulse on power-up and continuous overload or short circuit of outputs
Output Response TimeOpposed mode: 1.5 ms ON, 0.75 ms OFF

Retro: 3 ms ON and OFF

Diffuse and Fixed Field: 3 ms ON, 1.5 ms OFF

Note: 100 ms delay on power-up; outputs do not conduct during this time.
RepeatabilityOpposed mode: 190 µs

Retro: 585 µs

Diffuse and Fixed Field: 185 µs
Effective Beam13 mm for opposed mode sensors
AdjustmentsDiffuse models only: single turn rear panel sensitivity control
ConstructionHousing: Zinc die cast with nickel plating

Lens: PMMA or PC (opposed mode only)

Black Cover: PBT polyester housing
IndicatorsTwo LEDs (Green and Yellow)
