The Kansai rotary level switch (Japan) LS series is a rotary paddle switch for powders and granules: the paddle rotates continuously and the switch actuates when material stops it. Heat-resistant versions to 150 °C (LS-H), 100 VAC or 200 VAC supply, 3/4″ screw mounting. ISE supplies genuine Kansai switches, with ATEX dust versions where required (EN 60079-31).
