Use
Spindle limit switches of the SNS 007 series can be used as safety limit switches in main current and control circuits, for limiting rotational movements (safety limit switch or operating limit switch), as an electrical interlock or as an alarm. They are particularly suitable for devices in which there is a hard feedback between the rotation of the actuator and the required limitation.
Areas of application are primarily winches, hoists, sluice gates and travel stops, as well as transport devices for the extraction of raw materials used in extreme working environments and operating conditions.
How it works
The movable nut, which is guided in a protective housing, moves along a spindle driven by a motor. The travel of the sliding nut on the thread of the switching spindle is limited by 2 adjustable stops, which must be set before commissioning.
If the end position is reached, the travel nut runs over one of the stops and causes the switch to rotate. This rotational movement deflects the roller lever to the side, resulting in instantaneous shifting.
