ELFZex 125

Modular Linear Actuator, External Roller Bearing Guided, External Explosion Rated Belt Driven, Model ELFZex, 125

The ELFZex is a carriage driven actuator with single fixed belt. Beacuase the single belt wraps around with both ends and is fixed to the carriage, a larger capacity can be realized.

Like the ELFZ, the ELFZex Actuator is suitable for use according to the intended purpose in potentially explosive areas (see ATEX 95 marking). An operating manual is included in the scope of delivery. The system is certified for the following areas:

ATEX 95 II 2G EEx c IIB T4:

All application areas except for underground mining. Gas atmosphere category 2, explosion protection category: protection due to secure construction (design security). Equipment group IIB. Temperature class T4=135°C

ATEX 95 II 3D T125°C:

All application areas except for underground mining. Dust atmosphere category 3. Maximum permissible surface temperature: 125°C.
