Sensopad Ltd

Sensopad Limited is a high-tech company commercialising a breakthrough patented, non-contact inductive sensing technology. The Sensopad(TM) technology is perhaps the most versatile sensing technology on the market and can be used to manufacture:

Controls (switches) for industrial, medical, transportation and military markets

• High-end, high-functionality switches and buttons
  
• Complex user interfaces where non-contact sensing is required
  
• Industrial, medical and safety-critical joysticks
  
• Industrial, medical and aerospace trackballs
  
• Flat medical keyboards
  
  

Intelligent sensors for industrial, medical, transportation and military markets

• LVDT linear and RVDT rotary variable differential transformer replacements
  
• Linear and rotary absolute and incremental encoders
  
• Proportional and bi-state proximity sensors
  
• Proportional fluid level and flow rate sensors
  
• Force/load and pressure sensors
  
  

The key advantages of the technology are:

• Non-contact, absolute position sensing
  
• Low cost (lower potential sensor costs than Hall effect)
  
• Higher versatility (more sensing geometries)
  
• High resolution and accuracy
  
• Ability to multiplex sensors
  
• Sealable to IP68
  
• High temperature sensor head capability
  
• Compact form factor
  
• High tolerance to misalignment, magnetic fields and EMC
  
  

We supply sensor solutions to a wide number of OEMs and system manufacturers. Many solutions are off-the-shelf, although we do also undertake bespoke developments. The cost of our standard rotary or linear encoder product is competitive to that of a Hall effect product, but with significant performance benefits.
