The features of a roller lever limit switch include a lever with a roller at the end that oscillates. It translates either linear or rotational movement into switch activation. It is appropriate for use in high-speed applications such as textile machines or paper mills due to its unique roller design that minimizes friction and wear as it contacts the moving parts. The lever angle and roller size can be altered to adapt to specific mechanisms, and seal IP67 means no dust or coolant can penetrate the sealed housing protecting the switch in metalworking applications.
