Performance O

High reading performance

Thanks to 3D ID System technology, SPECTRE ATX4 offers the best performance with long-distance identification capacity of up to 6 m / 19.7 ft*.

Its high performance makes SPECTER ATX4 the most suitable industrial RFID reader for high volume moving applications in ATEX zones.

* ATTENTION, information on reading speeds, performances, and distances: measured at the center of the antenna, depend on the type of tag, the type of support and its positioning, the number and configuration of the antennas, the temperature, and the supply voltage. Installation conditions and the environment may affect reading speeds, performance, and distances. 

Multi technos O

Modular and scalable

With its 4 remote and independent antennas, SPECTRE ATX4 adapts to all your requirements, for your current and future projects.

The modularity of SPECTRE ATX4 makes it possible to anticipate changes in application cases and limits the costs associated with change.

The SPECTRE ATX4 reader supports all types of passive UHF tags (without battery) guaranteeing:

  • a virtually unlimited lifespan,
  • controlled investments with a cost 3 to 5 times lower than other active technologies,
  • the elimination of maintenance costs.

Ease of integration and installation


SPECTRE ATX4 is interoperable with existing industrial infrastructures.

Power over Ethernet (PoE)* allows the reader to be connected directly via Ethernet to the business software or to the middleware without any additional connection or power supply.

The reader offers 4 inputs (for detection cells, sensors, etc.) and 4 outputs (for light columns, rotating beacons, remote industrial buzzers, etc.). GPIOs simplify the on-site integration and configuration of customer applications (gantry, conveyor, shuttle, tunnel, etc.).

The wall and mast mounting system of the remote antennas in VESA 75x75 standard allows numerous installation configurations.

The different lengths of ultra-flexible coaxial cables (1.5, 3, 9 and 12 m / 4.9, 9.8, 29.5 and 39.4 ft) and their possibility of serial connection, offer great flexibility of installation on site.

*Requires a PoE switch or injector.
