EMR 18 SERIES
  FEATURES  

  • Low coil resistance.
  • Less than 15 mA Pull-in-Current possible.
  • Coil-contact isolation voltage up to 4250VDC/3000VAC.
  • Position of pin is optional.
  • Wide operation current and low power consumption.
  • A sealed metal outer case is used to prevent interference by magnetic fields and also to protect the coil during PCB assembly.
  • This product of line sense reed relay are designed for use as telephone line busy detectors.
