RKEY kapacitive sensoren er 51 mm X 51 mm, der giver nem at bruge ikke-mekanisk berøringsskifte til miljøforseglede miljøer og interaktive displays som musikafspilningsstationer.

RKEY kapacitive sensoren er selvkalibrerende og yderst robuste for de hårdeste miljøer.

RKEY kan monteres bag forskellige materialer - plast, træ og glas til en maksimal tykkelse på 10 mm.

Driftstemperaturområde på -40 ° C til + 85 ° C er det velegnet til forskellige ekstreme omgivelser.FEATURES

rKey Overview

The rKey Capacitive Touch Key Module is an easy way to add user input to your project.

  • Auto-calibration
    • The rKey auto-calibrates on power-up to maximize effectiveness through whatever panel material and thickness is used (up to 0.4”/10mm).
  • Durable
    • Because there are no moving parts, and the rKey can be mounted behind a sealed panel, possibility of physical damage is at a minimum.
  • Low Power
    • Using break-through technology, the rKey uses extremely little power to detect touches. At 5.0V, less than 80 μA are needed.
  • Separate LED control
    • To have complex visual feedback, the LED on-board the rKey can be controlled separately by a microcontroller. For simple touch feedback, the rKey output can be connected to the LED input.
