4.3 Parameters for ATEX applications

This section provides useful parameters and information to integrate LARA-R6 series modules in

applications intended for use in areas with potentially explosive atmospheres (ATEX), describing:

•

Total internal capacitance and inductance of LARA-R6 series modules (see Table 32)

•

Maximum RF output power at the antenna pin of LARA-R6 series modules (see Table 33)

☞ Any specific applicable requirement for the implementation of the host apparatus integrating the

modules, intended for use in potentially explosive atmospheres, must be fulfilled according to the

exact applicable standards: check the detailed requisites on the pertinent normative for the

application, as for example IEC 60079-0 [16], IEC 60079-11 [17], IEC 60079-26 [18] standards.

☞ The certification of the application device that integrates a LARA-R6 series module and the

compliance of the application device with all the applicable certification schemes, directives and

standards required for use in potentially explosive atmospheres are the sole responsibility of the

application device manufacturer.
