C-Mount; Emi And Esd Consideration - Smartek Vision Giganetix GC Series User Manual

1.2.3 C-Mount

A C-Mount is a type of lens mount commonly found on 16mm movie cameras, closed-circuit television
cameras (CCTV), trinocular microscope photo tubes and CCD/CMOS digital cameras. C-Mount lenses
provide a male thread which mates with a female thread on the camera. The thread is nominally 25.4mm
[1"] in diameter, with 32 threads per inch, designated as "1-32 UN 2A" in the ANSI B1.1 standard for unified
screw threads. The flange focal distance is 17.526mm [0.69"] and thread length 3.8mm [0.15"].

1.3 EMI and ESD Consideration

Excessive EMI and ESD can cause problems with your camera such as false triggering or can cause the
camera to suddenly stop capturing images. EMI and ESD can also have a negative impact on the quality of
the image data transmitted by the camera.
To avoid problems with EMI and ESD, you should follow these general guidelines:
Use high quality shielded cables. The use of high quality cables is one of the best defenses against
EMI and ESD.
Try to use camera cables with correct length and try to run the camera cables and power cables
parallel to each other. Avoid coiling camera cables.
Avoid placing camera cables parallel to wires carrying high-current, switching voltages such as wires
supplying stepper motors or electrical devices that employ switching technology.
Attempt to connect all grounds to a single point, e.g. use a single power outlet for the entire system
and connect all grounds to the single outlet.
Use a line filter on the main power supply.
Install the camera and camera cables as far as possible from devices generating sparks.
Decrease the risk of electrostatic discharge by taking the following measures:
Use conductive materials at the point of installation.
Use suitable clothing (cotton) and shoes.
Control the humidity in your environment. Low humidity can cause ESD problems.
