Introduction
The actuator LA27 is a powerful actuator designed for a variety of medical applications. It is developed forboth push and pull applications and has a very robust construction because of the ultrasonic-welded plastichousing.
The LA27 is equipped with a plug to connect an exchangeable cable with Mini-Fit connector. This gives thepossibility to order standard actuators and combine them with different cable lengths.

Features and options• 24V DC permanent magnet motor• Thrust up to 6000 N (in push application)• Thrust up to 4000 N (in a pull application)• Elegant and compact design with small installation dimensions• Protection class: IPX4, IPX6
• Colour: Light grey (RAL7035) or dark grey (RAL 7016)• Built-in end stop switches (not adjustable)• Possible to mount on control box CB6 by means of a special mounting clip (article no. 009271002 isdelivered with CB6)
• Scratch and wear resistent powder-painted steel inner tube
• Brake ensures the self-locking ability in either push or pull directions. There will always be a reduction of
the self-locking characteristic when the actuator is run in the opposite direction of the brake direction(see table 1)• Noise level 50dB(A), actuator not loaded

Usage
Duty cycle: 			

2/18; 2 minutes continuous use followed by 18 minutes not in use

Ambient temperature: 		

+5 oC to +40 oC (the actuator must also have this temperature)

Approval:			

IEC 60601-1, ANSI/AAMI ES 60601-1, CAN/CSA C-22.2 No. 60601-1

With connection to a static voltage power supply of 33 V, the lifetime could be reduced to 5000 cycles (at aconstant load of 6,000 N).
