Detector for bugs, electronic devices, and SIM cards with non-linear junctions

The EN-NLJDSCOPE is an advanced non-linear junction detector, an essential technology in the security and anti-surveillance sector. Utilizing components such as diodes and transistors present in circuits, this technology detects hidden electronic devices, even when turned off, by the reflected signal they emit when exposed to radio waves.

This makes the EN-NLJDSCOPE an indispensable tool for security professionals who need to verify the presence of electronic threats in restricted or sensitive areas.


Compact and ergonomic design

The EN-NLJDSCOPE is lightweight and compact, weighing less than 700 grams and measuring only 39 x 10 x 4 cm. It is perfect for use in narrow and hard-to-reach spaces due to its ultra-thin 18 mm antenna. The practical design makes the EN-NLJDSCOPE ideal for field operations where speed and discretion are essential.


Technical features and operating modes

Operating modes and adjustable power

The EN-NLJDSCOPE offers two operating modes:

  • Pulse mode: maximum power of 10W and average power of 230 mW.

  • Continuous mode: power of 200 mW, ensuring operator safety.

In both modes, automatic frequency selection prevents interference with other equipment, allowing reliable operation even in complex electromagnetic environments.


High sensitivity and precise detection

With a receiver sensitivity of -110 dBm, the EN-NLJDSCOPE can detect ultra-small semiconductor elements, even those smaller than 1 cm². It can also detect a SIM card at a distance of 10-15 cm, making it particularly effective for identifying small-sized objects.


Safety and reliability

The EN-NLJDSCOPE is designed to ensure operator safety, working at high frequencies while minimizing signal exposure. A centralized interference protection system optimizes signal reception on the second harmonic, allowing effective operation even in reflective surface environments. AM decoding helps distinguish between natural and artificial semiconductors through headphones or speaker.


User interface and ease of use

Equipped with an intuitive interface and unified control buttons, the EN-NLJDSCOPE requires no preliminary settings, ensuring simple and immediate use for any field operation.


Package contents

The EN-NLJDSCOPE includes:

  • Wireless headphones: for discreet listening of detected signals.

  • Carrying case: lightweight and compact for protection and easy transportation of the device.
