    Capacitive Touch & Proximity Sensors from NXP


Capacitive proximity sensor and switch

For an optimized response to the environment, use NXP capacitive proximity sensors for detection and self-calibration. The sensors compensate for changes, such as varying humidity or contamination on the electrode.

New and updated products

PCF8883US

Capacitive proximity switch with auto-calibration, large voltage operating range and very low power consumption



Key features and benefits

  • Detects capacitance changes on a remote sensing plate
  • Proximity operation possible, no contact required
  • Changes in the static capacitance are automatically compensated through continuous auto-calibration
  • Operates when wearing gloves
  • Sensing plate and the IC can be separated by a distance of several metres
  • Useable with dirt on the touch area
  • Adjustable sensitivity
  • Works with any event that generates a pre-defined change in capacitance
  • Adjustable response time

Key applications

  • Mobile phones or portable entertainment units
  • Medical applications
  • Explosive environments
  • Vandal proofing
  • Under upholstery, handles, mats, glass, carpets, tiles etc.
