RLC-3-55-1.5G Example Application


Product Outline

RLC-3-55-1.5G is capable of maximum 1.5 Gbps signal transmission (unidirectional 1ch) from the rotor side to the stator side and up to 1 Mbps bidirectional signal transmission between the rotor side and stator side.
It is also capable of non-contacting signal transmission and non-contacting power supply (12V/15W) and permits 360-degree continuous rotation communication with a rotating body.
The channel for ultra-high-speed data transmission covers the transmission band of HD-SDI signals (SMTPE-292M). The low-speed data are bidirectional signals, so the product can be used for serial data transmission (RS232C, RS422, etc.) for controls.
