About the CTLB Threaded load button

The CTLB series threaded load buttons are designed for accurate compression force measurement in compact and demanding environments. The series includes three models — CTLB1, CTLB2 and CTLB3 — covering a wide range of capacities from 1 kg up to 5,000 kg (10,000 lb). Models from 50 kg and up are made of fully welded stainless steel for maximum durability and performance.

Usage conditions

Each model comes with a shielded 4-conductor cable (1 m or 2 m depending on the range), and optional versions include integrated TEDS chip, amplification, or digital output. These load buttons are ideal for force measurement in applications where space is extremely limited and high reliability is required.

Possible applications

  • Compression force monitoring in industrial assemblies
  • Robotics and automation
  • Tooling and clamping systems
  • OEM integration in compact force applications
  • Test rigs and validation labs

Advantages of choosing this product
