Handheld Non-Linear Junction Detector (NLJD)
The Handheld Non-Linear Junction Detector (NLJD) transmits at 2.4 GHz (4 W) and listens to 2nd and 3rd harmonic returns at 4.8 GHz and 7.2 GHz. It recognizes electronics whether active, passive, or powered off. The interface is intuitive and easy to use in high-stress settings. Signal rejection and gain control aid detection of weak junctions. The enclosure is machined aluminium, and antenna housing uses moulded plastic cover. It ships in a rugged military-standard carry case.
The detector signals via audible tone and optional demodulation through speaker or earphones. It indicates detected material type (“Silicon” or “Metal”) on screen. Even nano SIM cards show up within 20 cm. Weight is only 700 g, making handheld use practical. Battery runtime reaches up to 4.5 hours per charge. The unit matches sensitivity of larger “portable” systems, yet remains compact.
In field operations, the Handheld Non-Linear Junction Detector is integral to counter-implantation sweeps, technical surveillance countermeasures (TSCM), and secure facility inspections. Military EOD or intel teams sweep vehicles, rooms, or devices for hidden electronics. Similarly, naval platforms and embassy sites use it to find dormant circuits. Its light weight and long battery life allow sustained sweeps in demanding environments.
Operators trust this model for its balance of power and portability and Tactical Supply Pakistan offers it with local support, ensuring smooth deployment and training assistance in Pakistan.
Can this detector distinguish between silicon chips and simple metal objects?
Yes, it displays whether the detected junction is “Silicon” or “Metal,” enabling operators to filter out irrelevant metallic foil or structural elements.
