K40 Electronics is releasing the Defuser g5, its fifth-generation Defuser model. K40’s Defuser is the most advanced, sophisticated anti-laser technology ever designed to instantaneously detect, notify the driver, and jam the pulse laser light signal transmitted by every type of police laser gun. This allows a driver to avoid detection and ultimately a speeding ticket.

The biggest enhancement found in the new g5 model involves its Sync Interface. When a laser gun is detected, the sync feature fires infrared lights signals from up to four transponders simultaneously. This creates more jamming output to the laser gun than ever before.

The Defuser g5 also delivers greater performance for owners by providing 60% more Reception Diodes that will, in turn, increase detection of laser gun signals. In addition, there are 10 new, more powerful Laser Defusing Diodes in each of the four transponders.

“We believe that the improvements we’ve made with the Defuser g5 helps K40 continue its mission of offering customers the most technically advanced products available,” said Peggy Finley, President of K40 Electronics.


  • Maximum Coverage Protection: The in-vehicle sync interface can fire up to four Laser Defuser g5 transponders simultaneously for superior detection and maximum jamming output.
  • Only You Know You’re Protected: The Laser Defuser g5 generates a commonly experienced error code on police laser guns. This is an important feature in states where the use of laser jammers is restricted.
  • License Plate Mount: Ideal for protecting the rear of a vehicle, the license plate mount strategically positions the Laser Defuser g5 where police laser gun operators are trained to target while providing a stealthy, yet OEM external appearance.
  • Ultra-Compact Footprint for Discreet Placement
  • Sized similar to a slim automotive key fob or USB flash drive, the Laser Defuser Optix compact footprint allows easy and discreet installation into grilles and other tight spaces.
  • Updateable to Ensure Optimum Performance
  • The in-vehicle sync interface controller features a USB port so its system software can be updated as new police laser gun technology emerges.
  • Maximum Coverage Protection
  • The in-vehicle sync interface can fire up to five transponders simultaneously for superior detection and maximum jamming output.
  • Constant Transmit: The Laser Defuser g5 will continuously transmit a signal for the duration of the laser encounter.
  • Pulse Transmit: The Laser Defuser g5 will transmit a signal for 10 seconds so you can safely reduce speed. The system will then shut off for 30 seconds. At this point, the laser targeting police officer has obtained a slower speed reading for your vehicle while eliminating the suspicion of “jamming” where the use of laser jammers is prohibited.
  • Receive Only: For notification only. No signal will be emitted.
