Product Overview
Phares Gear Tooth Sensors are designed for industrial speed monitoring utilizing a wide variety of gear shapes and sizes. They detect other high iron content targets as well, such as bolt heads, key stock, etc., and also detect magnetic targets. Targets must be high iron content. Medium or low iron content is not a suitable target.
Phares Gear Tooth Sensors digital output signal is a square-wave signal which is directly proportional to the input (linear). The digital output signal is compatible with logic inputs (PLC, VFD, DCS, etc.) and other devices which can measure frequency directly. This includes Phares Industrial Panel Mount Tachometers and Zero Speed Switch Modules.
