ID12mmOD56mmThrough hole slip ring

Through hole slip ring ---BTH1256A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A standard through hole slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Its inner part rotates with a rotating shaft pass through the inner hole, so we call it " through hole slip ring"   It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.Parameters: Mechanical: Working speed1000rpmOperating temperature-40℃~ +100℃Contact materialPrecious metalIP GradeIP 54Electrical: Circuit6 ,12,18,24Current5A,10A ,15A,20A or  higher currentVoltage240V,380V,600V optionalDielectric strength≥1000V@50Hz between each circuitInsulation resistance1000MΩ@ 500VDCElectric noise≤7mΩLead wire size22AWG, 17AWG,UL, color Teflon, silver or tin platedLead wire length200mmCritical Dimension: ModelLength "L"CurrentFormula (A means No. Of ring)6 circuits12 circuits18circuitsBTH12562A/5A20+2.3×A33.8mm47.6mm61.4mm10A20+2.8×A37.8mm53.6mm70.4mm15A/20A20+3.8×A42.8mm65.6mm88.4mmFeatures of Through hole slip rings :
