PRODUCT DATA SHEET ACTUATOR LA3 Features: 12/24V DC permanent magnet motor Max. thrust up to 6 N (LA3LK) Stainless steel piston rod Duty cycle: Max. 1% or 6 min/hour at continuous use Ambient temperature +5 to +4 C Elegant and compact construction with small installation dimensions Protection class: IP51 / IP66 Colour: black Speed max. 65 mm/s (LA3 S-motor with 12 mm pitch) Low noise level Steel construction for all bearing parts Acme thread spindle for optimum efficiency Storage temperature -4 to +7 C Options: Extra powerful motor (S-motor) L-motor for system actuator IP66 (by ordering LA3 with plastic housing) Double-acting brake - increased self-locking ability (LA3 with 6 or 9 mm pitch + LA3 S-motor with 6 or 9 mm pitch and LA3L) which ensures that all these types are fully self-locking. Potentiometer for positioning the actuator. -1 K ohm, -5 K ohm or -1 K ohm. Optical encoder for positioning the actuator. 1 pulses pr. spindle revolution. Reed switch (only LA3L versions): 8 pulses pr. spindle revolution. Mechanical spline function. Safety feature by using the mechnical spline, the actuator can only push. Safety nut (only in push) Terminal cover (only LA3 L-motor versions) Ball screw (K) (only LA3 L-motor versions) Ball screw and safety nut (KAS) (only LA3 L-motor versions) Ball screw, safety nut and splines (KSM) (only LA3 L-motor versions) LA3 is a powerful actuator yet small enough to fit to most applications. The actuator can be supplied with options such as built-in potentiometer for servo operation or extra powerful motor for increased speed and strength (S-motor). In addition to industrial and agricultural applications, the actuator is also ideal for positioning satellite dishes. The system actuator LA3L (option) can be combined with LINAK control boxes and it is perfet for a variety of furniture applications.
