Integrated Circuit Detection in a Plastic Web

Overview

  • Economical fiber optic sensor for routine applications
  • 15-turn potentiometer for manual adjustment of sensitivity
  • 10 to 30V dc supply voltage with NPN or PNP output, depending on model
  • LED bargraph signal strength, sensing contrast, programming status and diagnostic warnings
  • Available in glass and plastic fiber optic models
  • Marginal gain indicator with alarm output

Product Specifications

Supply Voltage and Current10 to 30V dc @ 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 Complementary:one normally open (NO) and the other normally closed (NC); NC output may be wired as diagnostic alarm output by reversing power supply connections
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
Output Protection CircuitryProtected against false pulse on power-up; short-circuit protected
Output Response Time500 microseconds ON/OFF
Delay at Power-up0.1 second; outputs do not conduct during this time.
Repeatability130 microseconds
AdjustmentsAll models have a 15-turn sensitivity (Gain) control, clutched at both ends of travel.
Indicators2 LED Indicators:Green and Yellow
Green ON steady:power ON
Yellow ON steady:normally open output conducting
7-segment Red bargraph:lights to indicate relative received light signal strength
Segment #1 Red flashing:output overload
Segment #7 Red flashing:marginal excess gain
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
ConstructionBlack ABS housing with acrylic cover, stainless-steel M3 x 0.5 hardware for use with thermoplastic polyester mounting bracket (supplied); the plastic fiber clamping element is Acetal
Environmental RatingIEC IP66; NEMA 4
ConnectionsPVC-jacketed 2 m or 9 m attached cables, or 150 mm pigtail with 4-pin Pico-style QD. QD cables are ordered separately.
Operating ConditionsTemperature:-20° to +70° C
Relative humidity:90% @ 50° C (non-condensing)
