* This voltage depends on the supply voltage required for the sensor used (see table below)
NOTICE! The pin 1 is a voltage output of the camera. Do not apply an external voltage on these outputs thus this may be destroy the camera. |
You can check the color assignment of the cable on the Website directly at the specific accessory item.
The I/O connector of the USB 3 uEye LE can be equipped with a 2 x 4-pin connecting plug with a 1.27 mm (50 mil) lead spacing. IDS Imaging Development Systems GmbH shall not be liable for any damage to the camera or connected devices arising from installation of the connecting plug.
