Title
3A Series 3-Axis Force Load Cells
Key Features
Measures forces simultaneously in three perpendicular axes: Fx, Fy, Fz (tension & compression) Independent full-bridge output for each axis (mV/V) — no mathematical manipulation required Available force range: 10 N to 500 kN (4.5 lbf to 112k lbf) Low crosstalk between channels (typically ±1–±2% depending on model) Temperature compensated (compensated range: -10°C to +70°C; operating: -10°C to +85°C) Compact construction; designed to minimize eccentric loading effects Model-dependent ingress protection: 3A60A IP65, 3A120 IP66, 3A160/3A300/3A400 IP67 Standard electrical: mV/V rated output (±0.5 to ±1 mV/V nominal); max excitation voltage 10 V Includes 3 m cable with installed 37-pin D-type connector and mating connector (standard configuration) Safe overload: 150% of capacity; ultimate overload: 300% of rated output
