A speed sensor measures the rotational speed of a toothed wheel, shaft, perforated disc, pulse band or another rotating component and provides electrical signals for monitoring and control systems. Non-contact magnetic or electromagnetic measuring principles are typically used for this purpose.

Noris develops and manufactures speed sensors for railway and marine applications. They are used on traction motors, gearboxes and wheelsets in rail vehicles, as well as on marine engines, turbochargers, generators and shafts. Our portfolio includes standard sensors and customised solutions with measuring principles, mechanical designs and electrical connections tailored to the application.

• Non-contact measurement without mechanical wear at the sensing point
• Robust sensor designs for harsh operating conditions
• Sensor options with high immunity to electromagnetic interference
• Different measuring principles, output signals and channel configurations
• Customised housings, electrical connections and cable protection
• Sensor variants type-tested according to EN 50155 for railway applications
• Sensor variants with classification approvals for marine applications

Noris speed sensors are also used in engines and gearboxes of commercial and special-purpose vehicles. Typical applications include dump truck engines and special-purpose vehicle gearboxes, where robustness and durability are essential.

Hall-effect, inductive-magnetic, magnetoresistive and eddy-current principles offer different approaches to non-contact speed measurement. The appropriate technology depends on the target, required measuring range and installation conditions.

Depending on the sensor type and configuration, available options include multiple measuring channels, voltage or current outputs, galvanic isolation, standstill detection, direction-of-rotation detection and frequency multiplication.

The individual product pages provide technical data and details of the available configurations. Read more
