Speed Sensors
Reliable speed and direction sensing for railway applications
Rowe Hankins Speed Sensors use Hall-Effect technology to measure rotational speed and support direction detection across a range of railway and industrial applications. Designed to detect ferrous toothed target wheels, these sensors generate electrical output signals for integration into compatible monitoring and control systems.
The range includes dual-channel speed sensors with different output characteristics, zero-speed detection capabilities and mechanical configurations. With options suited to demanding operating environments, the range supports a variety of installation requirements and motion-sensing applications.
KEY FEATURES
Designed for reliable earth fault monitoring
Zero-Speed Detection
Selected sensor series support true zero-speed detection, making them suitable for applications that require monitoring when rotation stops.
Flexible Configurations
Available options include different cable lengths, connector types, mounting arrangements and mechanical configurations, depending on the selected series.
Built for Harsh Environments
Selected series feature stainless steel housings, IP67 environmental protection and resistance to shock and vibration.
Dual-Channel Sensing
Two sensing channels provide separate output signals for compatible monitoring and control systems.
Direction Detection
Phase-displaced outputs on suitable sensor variants support direction detection alongside rotational speed measurement.
Accurate Speed Measurement
Hall-Effect sensing technology detects rotating toothed target wheels to generate signals for rotational speed monitoring.

DUAL-CHANNEL HALL-EFFECT SPEED SENSORS
RHC-ME10AN Series
A dual-channel Hall-Effect speed sensor that generates two square-wave output signals for rotational speed measurement and optional direction detection. Configurable cable lengths, connector options and sensor nose lengths support different installation requirements.
TECHNOLOGY
How speed sensing works
Detecting rotational speed and direction through Hall-Effect technology
Hall-Effect speed sensors detect changes in the magnetic field as a ferrous toothed target wheel rotates past the sensor. These changes generate electrical output signals that can be used to measure rotational speed. On suitable dual-channel sensors, phase-displaced outputs also support direction detection, while selected models provide true zero-speed detection.
For the image on the right, I'd use a close-up of a railway wheel, toothed target wheel or axle-mounted sensor rather than the desert image currently in your section. That will make the technology immediately relevant to the product and keep the design consistent with the rest of the page.
