Intelligent Non-Linear Junction Detector (NLJD)
The Intelligent Non-Linear Junction Detector (NLJD) operates on a 2400MHz working band with transmission frequency spanning 2.4GHz to 2.5GHz. The device receives second and third harmonics at 4.8GHz–5.0GHz and 7.2GHz–7.5GHz respectively. Transmit power reaches 0–4W EIRP in maximum pulse mode, enabling detection range of 6 meters or greater. The unit measures 780mm × 177mm × 112mm and weighs under 1.8kg. It penetrates 370mm-thick brick walls and meets GA1236-2015 C-level certification.
The device features a replaceable lithium battery delivering 4 hours operational time per charge. Fast charging completes in 2.5 hours. The LCD interface displays target type discrimination, identifying mobile phones, semiconductor nodes, and metal corrosion nodes independently. Audio alerts transmit through headphones or external speakers. Vibration alerts provide silent notifications. IP54 protection ensures field durability. Operating temperature ranges from -30°C to +55°C with storage capability from -40°C to +70°C.
Security teams deploy the Intelligent Non-Linear Junction Detector (NLJD) during facility sweeps to locate concealed electronics. Operators scan walls, furniture, and containers to identify hidden cameras, listening devices, and unauthorized transmitters regardless of power status. Law enforcement units use it in correctional facilities and detention centers. Military and government agencies employ it for counter-surveillance operations. Investigators conduct electronic explosive detection and wire-tapping investigations. The device identifies semiconductor junctions through non-destructive testing using precise phase algorithms.
Tactical Supply Pakistan delivers this intelligent detector with advanced harmonic technology for professional security applications. The integrated mobile phone recognition combined with automatic target classification provides reliable threat detection across demanding environments.
How does the detector differentiate between genuine electronic devices and false positives from metal corrosion?
The device analyzes both 2nd and 3rd harmonic responses using phase algorithm processing. Genuine semiconductor junctions display stronger 2nd harmonics, while natural oxide corrosion produces dominant 3rd harmonic signals. The LCD display relays this distinction to the operator for accurate target classification.
