Overview

  • Retro-wave sensor —use of reference signal (retroreflective target) enables reliable detection of weak targets in the foreground
  • Retro-wave detection — output activates for objects detected in the foreground OR for loss of detection of the retroreflective target
  • Ignores objects in the background beyond the retroreflective target
  • Sensing field is configured via remote TEACH
  • Sensitivity and output settings configured with simple DIP switches
  • Sensor operates in Industrial, Scientific, and Medical (ISM) telecommunication band; no special license required
  • Rugged IP67 housing withstands harsh environments

Product Specifications

RangeThe sensor is able to detect a proper retroreflective target (see below) up to 12 meters, depending on target.
Detectable ObjectsObjects containing metal, water, or similar high-dielectric materials.
Operating PrincipleFrequency modulated continuous-wave (FMCW) radar
Operating Frequency24.00 to 24.25 GHz, ISM Band (varies slightly with model, depending on national telecom regulations)
Supply Voltage12 to 30V dc, less than 100 mA, exclusive of load
Supply Protection CircuitryProtected against reverse polarity and transient overvoltages
Delay at Power-upLess than 2 seconds
Output ConfigurationBipolar NPN/PNP output, 150mA; DIP switch 7 selects N.O. (default) or N.C. operation
Output ProtectionProtected against short circuit conditions
IndicatorsPower LED:Green (power ON)
Signal Strength LED:Red, flashes in proportion to signal strength. Steady on at 4x the sensitivity adjusted baseline (indicating 4x excess gain). Only indicates signal amplitude, not target distance.
Output LEDs:Yellow (output energized)/Red configuration)
Response TimeDIP-switch 8 selects ON/OFF response time
AdjustmentsDIP-switch-configurable sensitivity and output configuration; remote line teach of the retroreflective target
