Non-contacting 2-channel stainless-steel speed sensor, difference-Hall principle
Speed sensors of type FA5 are non-contacting 2-channel speed encoders with a stainless-steel sensor tube. They measure frequency in accordance with the difference-hall effect principle. They acquire the speed of ferromagnetic materials, e.g. gearwheels with various tooth shapes, screw heads, drill holes, apertures, grooves or pulse bands on smooth shafts (accessories). Their compact and robust design, as well as the relevant tests as per DIN EN 50155, make them ideal for applications in the field of transport technology, e.g. measuring speed at the traction motor, gearbox or wheelset. The sensors are available with various output signals:
Type | Measuring principle | Output signals | Signal pattern |
---|---|---|---|
FAHZ5 | Difference-hall | 2 square wave signals, | |
FAHS5 | Difference-hall | 2 square wave signals, | |
