The new Genie Nano-5G GigE Vision cameras from Teledyne DALSA provide high data transfer capabilities using industry-standard Ethernet technology at an attractive price point. With data transfer rates in excess of five gigabits per second possible over cable lengths up to 100m. The cameras also come with a choice of high performance Sony sensors.

With the new 5GBASE-T interface, the cameras can slot directly into existing GigE Vision systems since 5GBASE-T technology allows Ethernet links to offer data rates of up to five gigabits over commonly used Cat5e cables. The standard provides faster frame rates than USB3 Vision - equivalent to 585MB/s, with a further increase in bandwidth to 985MB/sec using Teledyne DALSA’s award winning TurboDrive technology. This compares to bandwidths of 360 to 400MB/s for USB3 Vision.

The inclusion of TurboDrive also means that the cameras can operate at data rates approaching that of 10 GigE Vision, yet they have none of the heat dissipation requirements associated with that technology. They are therefore much more compact and lightweight with a footprint of just 59x44x32mm in a robust metal body, which is approximately 25% of the volume of a 10GE Camera.

With internal acquisition rates approaching one gigabyte per second the Genie Nano 5G can operate burst mode and sequencing at the fastest capabilities of the latest generation of sensors. They can operate over a wide temperature range (-20 to +65°C) for imaging in harsh environments.

Genie Nano-5G cameras are available with a choice of high-performance Sony Pregius CMOS sensors with resolutions from 3.2 to 12Mpixels, which offer fast frame rates from 190 to 63fps. Higher frame rates can be achieved in partial scan mode. 

The image quality provided by these sensors, combined by the impressive data transfer rates makes these cameras suited for use in many different applications. These include: industrial automation, electronics manufacturing, packaging inspection, semiconductor inspection, PCB-AOI (automated optical inspection), sport and entertainment high speed capture as well as general machine vision applications.

In addition to simplified camera set-up using field proven Sapera LT software featuring CamExpert or the included CVB CameraSuite, the Genie Nano-5G has a high level of programmability.

Camera capabilities include:

  • Global electronic shutter with exposure control
  • Multi-exposure feature
  • Advanced sequencing, a multi-ROI feature
  • Metadata support
  • IEEE1588 (Precision Time Protocol)
  • Binning
  • Look-up-table

Teledyne DALSA’s Trigger to Image Reliability (T2IR) framework improves the reliability of the inspection system and protects from data loss.
