Army Non-Linear Junction Detector
An Army Non-Linear Junction Detector, often called an NLJD, is a handheld search tool that finds hidden electronic parts, even when they are switched off. We supply it from China for government, police and military procurement, as part of our bomb detection and army equipment range.
What an Army Non-Linear Junction Detector finds
Almost every circuit has tiny semiconductor junctions, such as diodes and transistors. An NLJD sends out a radio signal and then listens for the echo, called a harmonic, that these parts send back. Because it reacts to the parts themselves, it can point to a hidden recorder, a phone or the circuit of a device inside a wall, a car panel, furniture or a bag.
Search teams use this kind of detector during sweeps of meeting rooms, VIP routes and vehicles. A trained user learns to tell a real hit from the false returns that rusty metal can give. The tool shows where to look, and a hands-on search makes the final call.
Build, size and what we confirm
The specification table below is general for this group, with values marked as typical. Items in this range usually use mission-grade metal or composite parts, and the size and weight vary by model and duty. Because this listing does not yet state a confirmed spec, we match the model to your need before we quote. Please tell us:
- Where the detector will be used, such as rooms, vehicles or outdoor areas
- Whether a tender sets a frequency band, power output or battery life
- The quantity, the country of delivery and the date you need it
Related search equipment
An NLJD works well next to other tools. Teams often pair it with an army deep search metal detector for buried metal, or an army desktop explosives detector for trace checks. You can browse the full bomb detection and army equipment range for more.
