\nA Non-Linear Junction Detector (NLJD) is a device used to detect electronic components. It operates by transmitting a low-frequency signal and listening for harmonic responses characteristic of non-linear junctions found in semiconductors (diodes, transistors, integrated circuits). This allows it to locate electronic devices, such as listening devices, cameras, GPS trackers, or electronic components within an Improvised Explosive Device (IED), even if they are switched off.
\n<\/section>\n
\nNLJDs detect devices containing semiconductors, which are fundamental components of electronic circuits.
\n<\/section>\n
\nNLJDs are primarily used in technical surveillance counter-measures (TSCM) and Explosive Ordnance Disposal (EOD) or search operations to find hidden electronic devices or components of IEDs. They do not directly detect explosive materials themselves, but rather the electronic triggering or control components.
