5 ELECTROMECHANICAL ACME SCREW LINEAR ACTUATORS CLA LIMIT SWITCHES CAM-OPERATED: Code FC2: two electric stroke limit switches cam-operated. Code FC2X: two electric stroke limit switches cam-operated, with wiring connection to switch off the motor directly, without relais. Available for DC and AC 1-phase motors. Code FC3: three electric switches cam-operated: 2 for limit positions switching operations + 1 for intermediate position switching operation. GEARED POTENTIOMETER FOR POSITIONING CONTROL: Code POR 5K: Rotative potentiometer single turn 340, 5 kohm. The combination of a geared potentiometer with two cam-operated limit switches (code FC2 or code FC2X) provides the capability of positioning control with additional two switching operations.
