Smart Junction Boxes

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.

Lear’s Solid State Smart Junction Box (S3JB) replaces relays and fuses with solid state electronic drivers. These self-protecting devices improve quality and eliminate the need to service fuses and relays. S3JB technology reduces weight and packaging size up to 80%.
