LS and LSD

There are two types of LINAK^® limit switches, for actuators type LA22, LA30, LA30S, LS and LSD. 

The LSD type controls the stroke length of the actuator between two fixed end positions by cutting off the current to the motor. 

The LS type  yields a  signal in two fixed end positions, but requires a control unit to stop the actuator when the micro switches are activated.
