Quantum TMR 200° Arc Position Sensor

Quantum TMR 200° Arc Position Sensor

A robust, programmable 200 degree arc position sensor specifically designed to measure the tow angle of an America’s Cup racing yacht.

  • ± 100 degrees of arc measurement range
  • Rapid response rate of 5kHz
  • 12 bit Resolution
  • Analogue VDC Output
  • Hard anodised aluminium construction
  • IP67 rated for harsh marine environment
  • Non-contacting and solid-state for increased product lifespan


Quantum TMR Tow Angle Non-Contacting 200° Arc Position Sensor (KZ-050-01)

Developed for an America’s Cup yacht racing team, the robust arc position sensor is designed for tough marine environments and performs spectacularly across the full 200 degree measurement range. Developed to measure the angular position of a vessel being towed from a primary vessel, the data provides useful insight into key hull speed performance characteristics.

An integrated CPU located within the aluminium sensor housing creates an analogue voltage output for easy implementation into the teams data recorder. Leveraging the latest advancements of Tunnel Magnetoresistance sensing, Reventec’s state-of-the-art Quantum TMR technology offers superior accuracy compared to Hall Effect sensors and provides reliable readings across magnetic field strength fluctuations. The arc position sensor benefits from real-time measurement with a rapid update rate of 5kHz, enabling engineers to extract detailed data for analysis.

Featuring ingress protection of IP67, the durable sensor is designed to tolerate extreme weather conditions, corrosive sea water and shock or vibrations that occur from violent wave motion whilst delivering dependable data. With no moving parts, the sensor performs reliably across an operating temperature range of -40°C to +125°C (-40°F to +257°F).

Boasting advanced accuracies of ±0.5% of reading, the device is capable of achieving reliable measurements across large air gap distances and through up to 20mm of non-ferrous material such as aluminium or stainless steel. For this specific customer, the target magnet has been designed to measure an approximate 6mm air gap in line with their spatial constraints. Non-contacting, solid-state sensors minimises mechanical wear and improves the product lifespan. This arc position sensor is factory calibrated as standard for easy plug and play installation by the customer.

Whilst the sensor has a 200 degree measuring arc, all Reventec products are available for full customisation to ensure the best fit for your application. Sensor dimensions, measuring arc range, connector types and construction materials can be adapted to achieve a sensor solution that complements your existing vehicle or vessel and fits your spatial and weight constraints.


Options include:

  • Range of connector interfaces available including; MIL-DTL 38999, autosport or subsea.
  • Custom housing options to fit your application and offer analogue or CAN outputs without the need for external CPU processing.
