TAG-7: the new generation of
“made in Tattile” Line Scan Cameras


Tattile’s TAG-7 Series is a range of technologically advanced line scan cameras designed to satisfy the most stringent requirements of machine vision applications where high resolution and high speed performances are a must.

Provided with either GigE Vision or CameraLink interface, the Tattile TAG-7 Series is supplied with monochromatic or colour Awaiba CMOS sensors of the latest generation, with a resolution of 2k, 4k or 8k pixels. The optics are available in the C-mount (only 2k pixel resolution) or F-mount (4k and 8k pixels resolution) versions.TAG7_01_sx_corpo_portaottica_ottica72

Completely made in Tattile – with the only exception of the sensor – all the TAG-7s have the same compact size (only 62x62x36mm) and the same sturdy and stable mechanical construction. Therefore, they can be easily installed and integrated in any machine or production line, in particular in multi-camera systems.

The core of the system is an Altera FPGA that manages in real-time the sensor, the images and the signals, besides a wide range of capabilities inside the camera that were developed for image optimization. Moreover, the FPGA can be customized for implementing the special functions required by the application, that add themselves to the standard functions like sensor gain and offset management, white correction, black noise calibration and so on.

“Tattile significantly invested in the development of excellent calibration algorithms, specially of colour, to obtain a final image as similar as possible to the image detected by the human eye,” says Fulvio Pozzalini, Technical Product Manager Industrial, Tattile. “All our cameras are calibrated in the factory in a controlled environment, but the customer can perform again the calibration of black, lighting, etc. on the field to match them to the operating environment in which the camera is being used.”

The CameraLink versions can reach speeds up to 80 kHz, supporting the Base, Medium, Full and 80-bit modes. Moreover, the CameraLink TAG-7s can be easily integrated with any frame-grabber or make an integrated system with the Tattile M100 CLink Vision Controller.

“The integration in bundle with our M100 Vision Controllers allows to obtain a system that is guaranteed and supported by a single supplier, on which the customer can develop its application,” says Pozzalini.

In particular, the CameraLink version has its own power supply through the PoCL (Power over CameraLink) technology. Therefore, if the frame grabber supports the PoCL – as in the M100 CLink Vision Controller, for instance – the camera is directly powered through the data interface cable without requiring an external power supply, making the camera connection much easier.


On the other side, the TAG-7 GigE Vision versions don’t require any frame-grabber and offer a maximum speed of 49 kHz. They can be easily integrated in any processing unit that is compatible with the GigE Vision protocol, like the Tattile’s M100 GigE Vision Controller.

In the TAG-7 GigE Vision version also 3 digital input RS422 and 2 digital output RS422 ports are available.

Actually, the 2k, 4k and 8k pixels monochromatic or 2k and 4k pixels colour models for the TAG-7 GigE Vision Series and the 2k, 4k and 8k pixels monochromatic models for the TAG-7 CameraLink Series are available. At a short time also the 2k and 4k pixels colour models for the TAG-7 CameraLink Series will be released. Therefore, the customer will have the same capabilities and performances avaliable and, according to the speed required by the application, he will be able to select either a GigE Vision camera for medium speeds or a CameraLink camera for higher speeds.

The TAG-7 Series is a very recent product, that was released few months ago. Tattile is continuously investing specially in the development of FPGA capabilities, adding new functions, new calibrations, etc. to improve the added value offered both to the image and the customer.

“We are reveiving a very positive feedback from the market,” Pozzalini emphasizes. “The first success applications realized thanks to the TAG-7 Series demonstrate the colour fidelity features that can be obtained thanks to the advanced calibration algorithms of these cameras. In fact, the investments performed by Tattile allowed to obtain a really excellent colour quality. In applications like the sorting based on the colour or the printing quality control, the customer is therefore able to estimate even minimal colour variations.”
