Either portion of the ROTOCON can be the stationary or rotary part of the application, without affecting quality, longevity, or performance of the ROTOCON rotary electrical connector. It is absolutely critical however to allow flexibility between the rotary and stationary portion of the ROTOCON connector. The body or the shaft can be fixed, consequently allowing the opposite portion to move freely. Failure to do this will drastically shorten the lifetime of the ROTOCON.
