Evolution to S3JB™ Technology offering weight and size reductions up to 70%
At Lear, our array of power-distribution systems (called junction boxes) intelligently manages power distribution and functionality. Our portfolio ranges from passive-junction boxes to advanced smart boxes, which reduces mass and cost through parts consolidation and enhanced power distribution. We have continued our technology leadership by evolving the Smart Junction Box to its most recent form, the Solid State Smart Junction Box (S3JB™). It incorporates Solid State drivers, thus eliminating traditional fuses and relays.
Lear's junction box technology utilizes a total systems approach to achieve high quality power distribution systems. Our industry leading PCB technology reduces tooling, lead time, and cost. Our proprietary thermal management software ensures optimized copper weight and package size.
Lear Smart Junction boxes form the foundation of the Body Electrical/Electronic Subsystem by integrating the Body Control Module and Junction Box into a single entity to control body electronic functions and provide constant power and switched power distribution.
Solid State Smart Junction Box (S3JB™)
Lear's industry leading Solid State Smart Junction Box™ incorporates solid state drivers with self resetting "fuse" technology. This latest advancement in technology reduces weight up to 70% and trims packaging up to 80%.
