Metrol mini stopper limit switches incorporate a mechanical stop along with the limit switch function, eliminating the need for a separate stop in many applications. With 10-micron repeatability and high contact force, these stainless steel switches can be used in precision indexing/positioning applications. Metrol stopper bolt precision limit switches, which can take the place of a stop bolt and separate switch for indication, incorporate a mechanical stop along with the limit switch function and provide two tasks with one device by housing a high-accuracy switch in a stopper bolt. They are designed so the sensed parts come to a stop against them without damaging the switch.
