PL60 Under Speed Switches

The PL60 Under Speed Switch provides low-cost, reliable and a simple means of monitoring the rotational velocity of a shaft or other rotating equipment. When the belt speed or rotating speed slows down within the preset range, the PL60 switch outputs a signal for either alarm or shut down. This switch is housed in a weatherproof, hermetically sealed anti-corrosive enclosure, designed for exposure to harsh environments.
