Overview
The MK820 is a miniature load cell that packs high accuracy and high sensitivity into a small, lightweight housing. Its compact size and strong stability make it easy to integrate into space-constrained instruments, and it holds reliable output across varying environments.
Key Features
- Miniature, lightweight, easy to integrate
- High accuracy with high sensitivity
- Strong stability and environmental tolerance
- High accuracy (±1%F.S.) for precise measurement
- See reference table elastic element for durability and corrosion resistance
- Sealed to IP65 for reliable operation in harsh environments
Applications
Commonly built into medical devices, robotics, consumer electronics, and compact machinery for precision force and weight measurement where space is limited.
