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...
