Accredited ISO 17025 calibration certificate for these Series R04 Miniature Force Sensors force tools is be available on request (for an extra charge). Why Calibrate?


Mark-10 Series R04 smart sensors are designed for tension and compression measurement applications with tight space constraints. These extremely compact force sensors feature threaded holes on two sides, which can accept a variety of hooks and implements. Capacities available from 0.25 to 100 lbF [1 to 500 N]. Compatible with Mark-10 indicators (sold separately) through unique Plug & Test TM technology. Every capacity has the same miniature dimensions. The sensors feature outstanding mechanical overload protection and threaded holes on two sides for the mounting of attachments or implements.

Features and specs

  • Ultra-compact size, miniature design
  • Threaded holes for attachments
  • Capacities from 0.25 to 100 lbF
    (1 to 500 N)
  • Accuracy: ±0.2% of full scale + indicator
  • Safe overload: 200% of full scale
  • Weight: 0.015 lb [0.007 kg]
  • Member of the Plug & Test™ family of interchangeable sensors and indicators
  • Measures tensile and compressive forces
  • Warranty: 3 years
Unique Plug & Test TM technology allows for interchangeable sensors to be used with a Mark-10 indicator. All calibration and configuration data is saved in the smart connector. The Plug & Test TM connector locks into the receptacle in the indicator when fully inserted. Dual buttons on the indicator housing release the con- nector for easy removal. Gold plated spring contacts ensure long lasting and reliable connection Force is applied to these surfaces. Threaded holes are supplied on both sides to accommodate various mount- ing configurations and attachments.
