The bodies of the actuators are made of anodised aluminium, and piston rod is made
of aluminium, 1.4301 stainless steel or St52 galvanised steel. The actuators meet
requirements for acceptable interference emission defined by EN 55011. Internal limit
switches ensure turning off at end positions, and an electronic switch protects the device
against overload. Parallel electric connection is also possible (without the speed
synchronization). The standard size of the piston rod eye bolt is Ø8 (possible variants: Ø6,
Ø10).
Every actuator has a cable in light grey silicon insulation, 2.5 m long:
standard version: 2 x 2.5
mm2 / OD ~ Ø9 mm
for “E” option: 2 x 2.5 mm2 / 3 x 1.5 mm2 / OD ~Ø11 mm
Options on request:
