Zero Speed Switches

Process Control Systems produces high quality Zero Speed Switches for a variety of industrial applications. Maxigard™ Zero Speed Switches detect the presence or absence of rotational motion and provide a relay output proving rotation or indicating loss of rotation. The relay output(s) can be used to control interlocked equipment, or as inputs to PLC’s or other control devices.
