Causes of slip ring signal interference
Slip rings are rotary connectors, especially suitable for devices that need to rotate and transmit signals at the same time. However, sometimes during the operation of the equipment, signal distortion may occur. This is because the slip ring signal is interfered with. The following slip ring manufacturers will tell you the reasons for the interference of slip ring signals.
There are two main reasons for the interference of slip ring signals, one is the wire problem, and the other is the internal structure problem.
Different signals need to be transmitted, and different wires are used. Many signals are sensitive and require special wires, and the signal shielding effect must be done well, otherwise there will be signal loss or crosstalk. Slip ring manufacturers remind that the commonly used transmission signals of slip rings are switch/control signals, RS485/232 signals, video signals, low-frequency pulse signals, thermal resistance signals, strain gauge signals, VGA signals, solenoid valve signals, Profibus signals, encoder signals, TTL level signals, Canbus signals, 100M/1000M Ethernet and other signals.
If the slip ring is not shielded at a key position, it will cause signal crosstalk. Slip ring manufacturers remind that signal interference should be paid special attention to near the power ring, because the magnetic field near the power ring will cause some signals to be interfered. This requires slip ring manufacturers to pay attention to the isolation and shielding between the internal signals of the slip ring, and use special wires for special signals to ensure that the signal is not lost or crosstalked.
