HFisolator Series 9730

HFisolator Series 9730

Series 9730

  • Allows the use of standard antennas in hazardous areas
  • Compact design
  • Variants for 900 MHz, 2.4 and 5 GHz
  • Extremely wide temperature range
  • Flexible use

The HFisolator turns usual wireless signals into explosion-proof, intrinsically safe wireless signals.

The signals are transmitted galvanically isolated between the input and the output.

The transformation of the signal enables all advantages of intrinsic safety (Ex i/ I.S.) for the wireless signals: making use of the full spectrum of standard industrial antennas, making use of standard coax connectors and the fact that connecting or disconnecting the coax cable is pemitted without deenergizing the wireless device in hazardous locations.

The advantages of the HFisolator are especially obvious when it is used together a project-specific encapsulation (e.g. flameproof enclosures Ex d) of wireless devices for the operation in hazardous locations.

STAHL is the ideal partner to enable your wireless solution in hazardous loactions.
