Position limit switches


Position limit switches

Position limit switches are limit switches with an actuating lever equipped with a roller or similar feature. If a workpiece or part of the machine moves against this roller, a cam in the switch rotates; this cam actuates the contacts and an electrical signal is sent. The next work step is triggered.

Along with a simple roller lever, the switches can also have an angled roller lever or swiveling lever of adjustable length. The advantage of a roller is that the service life of the lever is longer and lower actuating forces are necessary. Position limit switches from Sitec are particularly suitable for larger parts of a machine.
