1 Way, 2 Way and 3 Way Pass Through High Voltage Solutions from Lear Connection Systems

 1 Way, 2 Way and 3 Way Pass Through High Voltage Solutions from Lear Connection Systems

Car manufacturers are offering more and more advanced vehicles, however they expect from their own suppliers simplicity and highly reliable solutions. Lear’s 1 way, 2 way and 3 way Pass Through high voltage solutions are addressing these customer needs.


  • Pass Throughs are bolted connection types used for bringing cables into electrical modules like input from High Voltage Battery to the Inverter Module or from the Module to eMotor/Generator.
  • The pass through cost effective solution is capable for fully electric vehicles as well as hybrid cars offering high performance for harsh environments like demanding vibration profiles, high temperature ranges and current loads up to 350 Amps thank to low contact resistance. They can handle up to 1500V and assure watertightness for high pressure spray conditions. Solid anti-rotation feature and custom design innovative eyelet developed for 95mm2 copper cable cross section make Lear’s solution to best in class.
