MK813 Miniature Load Cell

Overview

The MK813 miniature load cell is built for precision force measurement where space is limited: a compact, lightweight elastic element delivering high sensitivity, high accuracy and stable output. Its environmental tolerance and simple integration let it be embedded directly into finished products rather than bolted onto a conventional scale frame.

Key Features

Small size, low weight
High sensitivity, stable output
Low power design
Easy integration and mass production
High accuracy (±0.3%F.S) for precise measurement
Stainless Steel elastic element for durability and corrosion resistance

Applications

A good fit for medical devices, robotics, smart-home products and consumer electronics requiring force sensing in tight enclosures.
