(15) Description of product
The LA14 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
12 V or 24 V d.c. with push / pull specifications up to 750 N.
Type key:
LA 14 series
Type variants
The LA14 series of linear actuators can be delivered in different type variants in accordance with the
manufacturers ordering nomenclature (below). The different type variants, which do not involve the
design of the motor housing itself, has no influence on the Ex-protection principle Ex tb IIIC T135 °C
