'Linear-Mech,j 13. STROKE END SWITCHES AND POSITIONING CONTROL 13.3 Electric stroke end switches FC (linear actuators LMR Sries) Each of the two micro-switches is fitted in a slot with a cam for switches commutation. A screw allows to lock the assembly in the desired position, adjusting in this way the switching position. The nut with suitable shape makes the cams rotate, so to activate the switches. This cam-operated device provides a stable and self-keeping commutation of the switches. The MIN. RETRACTED LENGTH Lc of the actuator is adjusted and controlled by switch FC1. The MAX. EXTENDED...
