The NEx product families are designed for particularly critical explosion-protected applications. Rotary, part-turn and linear versions are available depending on movement, torque, force and stroke requirements.

Series
The overview shows the typical product families for rotary, part-turn and linear applications. Final design depends on approval requirements, environmental conditions and the mechanical task.

Compact to standard Zone 1 actuator series for rotary and part-turn movements.

Series for higher torques and robust use in demanding process environments.

Large torque class for robust part-turn and rotary movements in Zone 1 applications.

Linear actuators for Zone 1 linear positioning. NEx-K covers standard strokes; NEx-KA is designed for extended stroke ranges.

Compact Zone 1 linear unit for shorter strokes and precise linear adjustment.
Comparison
The comparison table makes the differences between rotary/part-turn and linear actuators easier to see and supports technical preselection.
