Junction Box Evolution to S3JB™ technology offering impressive weight and size reductions.
Lear’s industry leading Smart Junction Box (SJB) integrates passive junction box features with electronic module functionality. It uses microcontroller-based technology to switch power and control vehicle body functions. Lear’s SJB technology utilizes a total systems approach by optimizing and integrating control and power distribution functions into a single module.
Advanced functional integration reduces mass and cost through part count reduction. Lear’s Solid State Smart Junction Box allows relays and fuses to function through solid state electronic drivers. These self-protecting devices improve quality and eliminate the need to service fuses and relays. This latest advancement in technology reduces weight and packaging size up to 80% and wire gauge size up to 20%.
