Talking Intrinsically Safe with the Ex-Handy DZ Feature Phones

When it comes to mobile communication in dangerous working environments where there may be a chance that an errant spark or excessive heat could ignite a volatile atmosphere, your mobile communication device needs to be intrinsically safe.

What are intrinsically safe devices?

Intrinsically safe devices are defined as: ‘Equipment and wiring that is incapable of releasing sufficient electrical or thermal energy under normal operating conditions that could lead to the ignition of a specific hazardous atmospheric mixture in an easily ignited concentration’.  It stands to reason that in environmental conditions like these the equipment used in those areas will need to certified to specific intrinsically safe directives such as ATEX and IECEx.

Most modern smartphones may be feature-packed with all the latest hardware and software but when it comes to keeping users safe in potentially dangerous atmospheric conditions they are sadly lacking by not being intrinsically safe and potentially dangerous in certain locations.

ecom, a Pepperl + Fuchs Brand has the intrinsically safe answer to on-site mobile communications in the harshest of environments in the form of the Ex-Handy 10 DZ1 & DZ2 ATEX safe feature phones.
