ACME SCREW LINEAR ACTUATOR CLA 28 T CLA 28 T linear actuator differs from CLA 28 on the protective tube excution, which is made of zinc-plated steel, ext. 0 50 mm, allowing the fitting of a bracket with self-lubricating bushes on protective tube itself. The actuator can be hinged on these bushes, reducing by this way the attachments centre distance and improving the total resistance against push load buckling. A typical application is lifting motion on solar trackers. Standard head with threaded hollow bore OVERALL DIMENSIONS 27 030 BA CD O FRONT ATTACHMENT 77 50 , BALL JOINT CLEVIS END TS...

13. STROKE END SWITCHES AND POSITIONING CONTROL 13.4 Electric cam-operated stroke end switches (linear actuators CLA and CLB Sries) Code FC2: two electric cam-operated switches, wired on contact NC (to be connected into the exter-nal control circuit). On request, the switches can be wired on the contact NO or on the switch-over contact CS. (For available configurations please contact our Technical Dpt). Code FC2X: two electric cam-operated switches, internally wired between power supply and electric motor, in order to switch off the power supply directly, without relays. Available for...
