Hall Effect Zero Speed Sensors

Hall Effect speed sensors are integrated units containing the transducer, magnet (as applicable), and electronics that are used to provide zero speed sensing. We manufacture them in both oriented and non-oriented models.

Oriented »

The H series of Hall Effect sensors are oriented, which means that they require orientation to the direction of target movement. They are recommended for use with finer pitch targets.

Non-Oriented »

Non-oriented HN series does not require orientation, offering ease of installation.

Quadrature Output »

Dual Channel Hall Effect sensors with quadrature output are offered with or without direction logic. Isolated and differential output options are available.

Motion Sensors (MSI) Hall Effect (HE) sensors are true zero speed sensing devices that utilize a special solid state transducer chip that produces an output voltage when subjected to magnetic field changes. Hall Effect transducers are produced in many different sensitivities, configurations and output types; analog or digital. MSI standard HE sensors fall into two general categories; oriented - requires orientation to the direction of travel of the target and non-oriented – which does not, but generally has poorer performance when used with finer pitch targets. Standard series are Oriented: H HD and Non-oriented: HN.

Hall Effect sensors have limitations; "drag" when used with internal magnetics (zero-drag designs are possible employing external magnetic excitation), limited maximum sensing distance (compared to other technologies such as RF and maximum operating temperature compared to variable reluctance (VR).
