Traction control

Traction control helps optimise the transfer of tractive force between wheel and rail. During acceleration, the system monitors wheelset speed to detect excessive wheel slip and adjusts the tractive effort accordingly. This supports reliable acceleration, reduces wheel and rail wear and helps maintain traction in changing adhesion conditions.

Speed sensors provide the precise wheelset speed signals required for this control process. Noris speed sensors are designed for demanding railway applications and provide reliable measurement even under harsh environmental conditions.

The FAM52 is a two-channel magnetoresistive speed sensor designed for precise speed measurement in demanding railway applications. Its high signal resolution makes it particularly suitable for traction control and other applications requiring accurate wheelset speed signals.

• Magnetoresistive measuring principle
• Two measuring channels
• High signal resolution through frequency multiplication
• Suitable for wheelset applications
• High immunity to electromagnetic interference
• Robust stainless-steel flange housing
• Type-tested according to EN 50155

The FAM52 can be used with both toothed wheels and magnetic pole wheels. Frequency multiplication increases the resolution of the output signal and enables precise speed measurement even when the available number of pulses is limited.

• Up to 4x frequency multiplication with toothed wheels
• Up to 8x frequency multiplication with magnetic pole wheels
• Other multiplication factors available on request
• Individual adaptation to application-specific requirements
