Overview

  • Easy push-button TEACH-mode programming to automatically adjust sensitivity to optimal setting
  • 10 to 30V dc supply voltage with NPN or PNP output, depending on model
  • Light-operate or dark-operate selectable
  • Available with low-contrast sensing
  • Switching threshold setting for subtle changes, such as web flutter
  • LED bargraph for signal strength, sensing contrast, programming status and diagnostic warnings
  • Glass and plastic fiber optic models
  • Marginal gain indicator with alarm output

Product Specifications

Supply Voltage and Current10 to 30V dc (10% max. ripple) @ 45 mA max. (exclusive of load)
RangeRange varies by sensing mode and fiber optics used
Supply Protection CircuitryProtected against reverse polarity and transient voltage
Output ConfigurationNPN (current sinking) or PNP (current sourcing), depending on model Load output:normally open (NO) and programmable light or dark operate
Alarm output:normally open (NO)
Output Rating150 mA max. each output; total load may not exceed 150 mA OFF-state leakage current:less than 10 µA @ 30V dc
ON-state saturation voltage:less than 1V @ 10 mA dc; less than 1.5V @ 150 mA dc

Green ON steady:power ON
Green flashing:ready for TEACH mode; 1 Hz when ready to learn first condition; 2 Hz for second condition
Yellow ON steady:lights for load output ON (conducting)
7-segment Red bargraph:lights to indicate relative received light signal strength, output program settings, relative contrast level and alarm
Mounting BracketD12 Sensors mount directly to a standard DIN rail, or may be through-hole mounted using the supplied mounting bracket and M3 x 0.5 hardware
