1. Introduction
1.1. Series Introduction
The MER-U3 and MER-U3-L cameras of MERCURY USB3 Vision series are DAHENG IMAGING's mature
area scan industrial digital camera, featuring outstanding performance, compact size, outstanding
price/performance ratio, which are easy to install and use. The MER-U3 series camera integrates I/O
(GPIO) interfaces to provide external power supply and various control operations such as external trigger
and strobe. Compared to the MER-U3 series, the MER-U3-L series camera has no I/O (GPIO) interfaces,
so it is lighter and more cost effective. The MER-U3 and MER-U3-L series cameras are available in a
variety of resolutions and frame rates, and are available with CCD and CMOS sensors from leading chip
manufacturers.
The MER-U3 and MER-U3-L series digital cameras transmit image data through the USB3.0 data interface.
Thanks to the locking screw connectors, the MERCURY series cameras can secure the reliability of
cameras deployed in harsh industrial environments. Featuring high reliability and high price/performance
ratio, the MERCURY series cameras are especially suitable for machine vision applications such as
industrial inspection, medical, scientific research, education, security and so on.And the MERCURY USB3
Vision series camera will be a good choice for the users who are demanding on the camera size.
1.2. Naming Rules
Details of the MERCURY USB3 Visionseries camera are given in the section 4. Each camera model name
is determined by its sensor's maximum resolution, maximum frame rate at maximum resolution, the
color/monochrome type of the sensor, and whether external trigger interfaces are provided, etc.
