4-1. Load Cell Connection
The load cell connector used by F805AT-BC is HIROSE JR16PN-7S (supplied) or its
equivalent. Voltage value used to excite the load cell is either 5 or 10 volts (selectable),
and max. current is 120mA.
4-1-1. 6-wire load cell connection
F805AT-BC uses a 6-wire load cell connector (remote sensing capable). Always use a
shielded 6-wire cable to connect the load cell, and avoid running them close to noisy
lines (power drive lines, or digital equipment cables) and AC lines.
“Remote sensing” method controls excitation voltage near the load cell to avoid
excitation voltage fluctuation due to the change in wire resistance caused by
temperature change.
