Analogue Junction Boxes
Multiple Load Cell Systems
For Connection and Corner Adjustment
Easy Connection
All connections are made to screw type
terminal blocks thus no soldering is
required. The corner adjustment is done
by precise trim pots and done quickly
and reliably.
Stainless Steel Housing
All junction boxes are made from stainless steel and provide the best reliability
even in harsh industrial environments.
Mounting plates allow easy attachment
to wall or ground.
High Protection Class
The high protection class of all junction
boxes guarantees a long and reliable
lifetime even in the most demanding
applications in the food and pharmaceutical industries.
Analogue Junction Boxes
All junction boxes feature:
• Easy connection to screw type terminal blocks
• Quick corner adjustment by trim pots
• Stainless steel enclosure
• IP65 protection class
• Mounting brackets
The METTLER TOLEDO analogue junction boxes are
suitable for quick and simple connection of multiple
load cells to weighing electronics. The integrated trim
pots allow one to minimize corner error by simply
using a screw driver - no soldering or seperate resistors necessary. The stainless steel housing provides
best reliability.
