SSH-G01

Hall-Effect Gear Tooth Speed and Direction Sensor

The flange mount gear tooth speed and direction sensors of Piher Sensing Systems are designed to precisely calculate speed and direction of ferrous gears in demanding environments such as vehicle transmissions. The hall-effect sensor measures the variation in flux found in the airgap between the magnet and the passing teeth. Based on its touchless technology and rugged design the SSH-G01 sensor provides true long-term reliability.

Key Features:

■ “Plug and play” Speed and direction feedback with not need of calibration.
■ Operating temperature of 125ºC (higher on demand)
■ Fast and near zero speed sensing capable
■ Compact and rugged for automotive & industrial areas
■ Sealed for harsh environments: IP67
■ Resistant to moist and high vibration environments such as engines, transmissions, brakes and chassis systems
■ ESD protection
■ Easily customizeable cable or connector interface
