All informaƟon is subject to TT Electronics’ own data and is considered accurate at Ɵme of going to print. DescripƟon: The OP181 is a surface mount emiƩer component incorporaƟng a high power 940nm LED. The LED die is lead frame mounted and overmolded, incorporaƟng a lens to achieve excellent beam angle characterisƟcs. The final product provides superior output irradiance at low drive currents. While this part has been designed specifically for the smart power meter industry, other applicaƟons are certainly possible. ApplicaƟons:

  • Smart power meter opƟcal port
  • Over the air communicaƟons Features:
  • 940nm Wavelength
  • Up to 256kbps OperaƟon
  • Compliant with Smart Power Meter Standard ANSI C12.18
  • Lensed for Maximum Performance
  • Reverse Gull Wing Design
  • CompaƟble with OPL6000 Receiver Component Dimensions are ±0.005 unless otherwise specified Note: The cathode lead is the wider of the two leads as indicated above but also has red strip indicator on the boƩom of the lead.
