17Proximity sensors

2

Sensors commonly used in automation

3

Limit switches

Limit switch (LS1) in motor circuit

4

If the force is removed, the lever restores its initial position by a return spring inside the limit switch

An external force is necessary to restore the lever to its initial position

Two types
