Image 1 of 1
A non-linear junction detector (NLJD) for detecting the electronic circuits commonly found in improvised explosive devices and radio transmitters.
Stock No:
(600-375)
Most sophisticated electronic circuits contain semi-conductors which are non-linear junctions. The Detector indicates the proximity of the device by means of an audio alarm.

The detector consists of a control unit, which also contains a rechargeablebattery, and is worn on the users belt or with the shoulder straps supplied. Thecontrol unit also contains a speaker which emits an alarm, although  theheadphones (supplied) can be used  for covert use.

The antenna wand which contains the transmitter and receiver is extendable from300mm to 800mm to allow the ground to be searched with the operator in aconvenient standing position. A soft plastic foam cover protects the antenna, aswell as the surfaces being scanned, from damage.Four diodes mounted on a printed circuit board are supplied as a reference testpiece. All items are supplied in a robust foam lined carry case. An optionalexternal battery is available to facilitate extended periods of use if required.


Additional Information
Typical applications for the use of a non-linear junction detector are the following:

VIP Protection support - The NLJD can be used to search for both 'bugs' and electronic IED's prior to a VIP visit.

Threat response - It can also be used for searching large complex areas where devices may be hidden in any number of places. e.g. incendiary devices placed indepartment stores or conference halls.

Post incident follow-up - Because semi-conductors do not need to be powered to be detected, the NLJD can be used to find parts of circuits after an incident toprovide forensic evidence or intelligence regarding the source of the device.
