Budget junction boxes simplify connecting analog load cells

The latest design of HBM’s VKK1-4 junction box features an integrated resistor network for precise off-center load compensation in scales.

The junction boxes are used for connecting four strain-gage (SG) load cells and need only three steps to get results:

• Load scale corners
• Read correction value from diagram
• Activate balancing resistor

Additional features include EMC-compliant cable glands for cable diameters ranging from 4 to 6.5 mm. HBM has devised a shielding design that provides full EMC (electromagnetic compatibility) in compliance with the EN45501 standard or the international OIML R76 guide.

Special EMC-compliant cable glands for diameters up to 7.5 mm are also available. These enable cables with larger diameters to be used for connection to the scale electronics over longer distances.
