The “P” series actuators offer no built-in controller, but do provide an analog position feedback signal that can be input to an external controller. The “P” series can be used with our Linear Actuator Control Board (LAC) to give the “P” series the ability to be controlled with USB (via our Configuration Utility Software), 0-5v, 4-20mA, RC Servo or PWM. On board adjustment of speed, sensitivity and stroke limits are available via the LAC. The “P” series are available in 6v or 12v models.
