Proprietary Technologies and Advantages
KappaSense’s technical excellence is based on several pillars that guarantee high-quality products and exceptional reliability.
-
Capacitive technology: Capacitive technology offers significant advantages over optical and magnetic technologies: immunity to magnetic fields, insensitivity to dust and liquids, and resistance to vibrations.
-
FREEe™ Platform (Cable-less Readhead) : Patented technology in which the readhead is a passive device weighing only 3 grams, requiring no moving cables. All encoder cables are static and connected to the scale, which significantly improves system reliability by eliminating cable wear issues on moving parts.
-
Ultra-wide mounting tolerances: KappaSense capacitive encoders offer exceptional installation flexibility, with extended mounting tolerances, including an air gap of up to 3 mm. This feature simplifies integration and allows use in vibration-prone environments.
-
Resistance to harsh environments: Solutions are designed to operate reliably in difficult conditions: extended temperature range (-40°C to +85°C), immunity to contamination (dust, grease), and resistance to vibration and shock.
-
Vacuum compatibility: Available in vacuum-compatible versions (ultra-low outgassing) for applications requiring a controlled environment (semiconductors, research, aerospace).
Product Ranges
KappaSense offers a range of products covering market needs, from standard components to fully customized solutions.
1. FREEe™ Series
Capacitive linear encoder with cable-less readhead (passive, 3g). Wide mounting tolerances, ideal for vibrating environments and applications where cable reliability is critical.
2. µFREE™ Series
