Certificate No.:
IECEx TUN 14.0021X
Date of issue:
2024-12-19
EQUIPMENT:
Equipment and systems covered by this Certificate are as follows:
The LA36 series of linear actuators creates motion in a straight line, as contrasted with circular motion of a conventional electric motor. The
actuator consists of a motor, a gearbox and a spindle that causes the actuator to either extend or retract. The motor housing consists of a two-
part aluminium assembly with a cork gasket and an aluminium outer tube. The equipment is earthed externally through actuators fixation
points: the piston rod eye and the back fixture. The actuators are rated for 12V, 24V or 36V d.c. with push / pull specifications up to 10000 N.
odel LA36 can furthermore be delivered with an accessory, called
for mechanical fixing of a cable conduit, to make the power and signal cable rodent protected. This external cable gland has no influence on
the Ex-protection principle and the ingress protection is still kept IP6x.
The actuators are certified under the type LA36 including various type variants which has no influence on the ingress protection / Ex-
protection principle. The manufacturers
