This IP67 Basler acA2440-20gcIP67 camera offers a compact footprint for wet environments. Two M12 connectors on the back ensure the housing is completely sealed again dust and liquids. The lens cover is sold separately.

The ace series of cameras offer fantastic value. This IP67 model is built on the Sony Pregius IMX264 2/3" sensor. It offers 5 MP (2448 x 2048) resolution with astounding image quality: high quantum efficiency, wide dynamic range, and extremely low noise.

When this IP67 camera is configured to use the sensor's full resolution, it can deliver 23 frames/second ("fps"). However, when configured to use less resolution, the frame rate will increase. As examples, 2048 x 2048 delivers 27.6 fps, 2448 x 1080 delivers 43 fps, and 2448 x 480 delivers 93.1 fps. (Note maximum frame rate also depends on the output format, exposure time, and network hardware.)

Using a Power over Ethernet (“PoE”) configuration, a single cable may be used to apply camera power and to transfer data between this camera and a PC, keeping cable runs to a minimum. The Ethernet M12 connector is "X-coded". An auxiliary 5-pin M12 connector is provided for terminating the optically isolated input and output signals – there is one of each. The input may be configured to trigger image acquisition, reset the frame counter, or reset the software trigger count. The output may be configured to indicate acquisition trigger wait, exposure active, flash window, or timer active. Or the output may be controlled via a PC. The auxiliary connector may be used to power the camera if PoE is not available.

The Basler ace provides a full set of features to address a wide range of applications. Pixel data can be output in 8 or 12 bit depth. You may adjust the camera’s black level, gain, area of interest, input debounce, and trigger delay. It features automatic exposure control, pixel binning, horizontal image mirroring, event reporting, sending of test images, and a programmable lookup table. There are also “chunk” features that include a frame counter, time stamp, trigger input counter, and CRC checksum calculator. Note that not all features may be available when using third-party software.

This camera has a global shutter for “stop-action” imaging. The camera can output a flash window signal to control the light source.

Because this camera is GigE Vision and GenICam compliant, there are many third party software applications and API’s that are compatible. Basler offers their royalty-free Pylon SDK for 32 and 64 bit Windows, Linux and OS X platforms.
