How long the distance between a transmitter and a receiver of Wireless and batteryless pushbuttons?

The possible distance between a transmitter and a receiver is approximately:
  • 100 m/328 ft where there are no obstacles,
  • 25 m/82 ft if the receiver is installed in a metal housing or in a closed metal enclosure,
  • 300 m/984 ft if a relay-antenna is located between the transmitter and the receiver (receiver installed in a metal housing or in a closed metal enclosure).


(*) Typical values that may be modified by the application environment.
(**) Free field (unobstructed).
NOTE: 
  • The range may be increased by adding antenna ZBRA1.
  • The range is reduced if the transmitter is placed in a metal box (reduction factor: approx 10%).
  • Once wiring is complete, test the product in all possible active areas (while remaining within range).
The level of signal attenuation depends on the materials through which the signal will pass:

(*) Values for indication purposes only. Actual values depend on the thickness and nature of the material.
