I am using a 6 core shielded cable. In this 3 wires are used for a sensor and 3+1(shield) is used for a analog camera. All the cores take DC supply.
- (+)24 volt supply,
- output (24 volt digital and PNP output)
Output switching Frequency : 800 Hz
Response time : 600 microsecond
Note: No load supply current <10 mA & switching current is max 50mA, resistence load.
Camera 3 wires and 1 shield,
- (+)5volt supply
- Video signal
and the Shield is grounded
The issue is, there is lot of noise in the video that I see in the screen. I could make out that the noise is because of the power supply and signal from sensor. Because when ever I switch off the sensor, the noise disappears. Ideally I should have a separate cable for video signal and sensor, but because of space constrain (overall dia< 8mm) in my application, I cannot do it. Can electrical experts advice me on removing the noise from the cable ? Note: Current carried by the cable is in the order of milliAmp. Thank you all in advance.
