Overview
J-Box (junction box): a critical IP67/IP68-protected weighing connection component that balances multiple load cell signals and feeds the indicator.
The J-Box (junction box) is a critical electronic component that collects analog or digital signals from multiple load cells at a single point and transmits them to the weighing indicator. Signal trimming via potentiometers keeps the system balanced.
Especially on truck scales and large platform scales, it acts as the main terminal where data from each cell is merged losslessly and in balance. With a stainless steel or cast aluminium body, IP67/IP68 protection, lightning/surge protection and 4/6/8-cell connection capacity options, it is a long-lasting, reliable connection solution.
Features
01
Load cell output voltages are equalized with potentiometers.
02
Gives the same result regardless of load position.
03
Protects the indicator against lightning/surge.
04
4, 6 or 8-cell connection capacity options.
05
Stainless steel or cast aluminium body, IP67/IP68 protection.
06
Cable entries are sealed with watertight glands; desiccant packs are placed against moisture.
07
A digital J-Box addresses each cell separately, speeding up fault diagnosis.
08
Maintenance covers terminal checks, moisture/corrosion inspection and periodic corner (shift) tests.
Use Cases
Technical
“A scale without trim (corner) adjustment gives different results depending on load position on the platform; it must be balanced at first installation.”
