3 Product description 3.4 Technical data
Actuators NEx, NEx-K, NEx-KA, NEx-V 23
Gearbox
Maintenance-free steel spur gearing
Installation position
Any orientation
Switch
−
Switch function: changeover switch (NC/NO contact)
−
Switching capacity: max. 6 A, 250 V AC
Switches with gold-plated contacts are available for small switching loads and
low voltages.
NOTE
Limit switches and auxiliary switches are not suitable as signal encoders
for safety-related controls!
Therefore the proper functioning of the actuator must be monitored during
operation by further measures, e.g. additional sensors in the application.
Environmental conditions
The actuator can be used in potentially explosive areas of Zone 1 and
Zone 2 .
Actuator marking:
II 2G Ex db IIC Tx Gb and
II 2G Ex h IIC Tx Gb
Tx = temperature class = T3 or T4 or T5 or T6
Ambient temperature
-20 °C to +60 °C
(A thermostatic switch activates and deactivates the anti-condensate heater
when temperatures sink below 0 °C and rise above +15 °C respectively.)
Environmental conditions
see section “2.4.4 Protection classes IP66 /IP67 ”
Installation height
≤
2000m above sea level (standard)
> 2000m above sea level (option, consultation required)
3.4.7 Airborne noise emission
The airborne noise emission level induced by the actuator is < 70dB(A).
