The Omega LCMKD-50N is a subminiature compression load cell rated for 50 N (11.2 lb) capacity. It uses all-stainless-steel construction with high-performance bonded strain gages and an in-cable temperature-compensation board to deliver stable, repeatable force measurement when mounted on a smooth, flat surface.
Specifications sourced from the OMEGA LCKD/LCMKD Series datasheet.
Overview
Small in size but not in performance, the Omega LCMKD-50N is part of the LCKD/LCMKD subminiature compression load cell series, measuring loads from 10 N up to 5000 N across the family. Rugged all-stainless-steel construction and high-performance strain gages ensure superior linearity and stability, with temperature compensation handled by a miniature circuit board in the cable.
Best For
Compression force measurement in tight spaces — OEM equipment, bench and laboratory test stands, in-line press and clamping force monitoring, and embedded industrial load sensing where a low-profile, flat-mount cell is required.
