Tacho Units & Target Wheels
Reliable axle speed sensing for railway applications
Rowe Hankins Tacho Units and Target Wheels support reliable rotational speed and direction monitoring in railway applications. Designed for axle-mounted installations, tacho units combine speed-sensing technology with a toothed target wheel to provide an integrated solution for rail vehicle monitoring systems.
The range includes complete tacho unit assemblies and target wheels for compatible sensing arrangements. These products support applications including axle speed monitoring, train speed indication, wheel slip and slide protection, and rail vehicle control.

COMPLETE ASSEMBLY
ITAE606DA
The ITAE606DA Series combines a sealed dual-channel Hall-Effect sensor and toothed target wheel in an axle-mounted assembly. It provides current-source square-wave outputs for rotational speed monitoring and direction detection, with a design intended for demanding railway environments.
TECHNOLOGY
How Tacho Units and Target Wheels Work
Converting axle rotation into speed signals
A target wheel rotates with the railway axle, passing the sensing elements within the tacho unit. Hall-Effect technology detects the changing magnetic field associated with the toothed wheel and generates electrical output signals corresponding to rotational movement. Dual-channel, phase-shifted outputs can also support direction detection, allowing connected vehicle systems to monitor speed and direction.
