What are you looking for when considering the use of speed detection inside your electric drive? High IP-rating? Zero-Hz-capability? Different connectors? High temperature resistance?
We recommend, to have a close look on RHEINTACHO´s speed sensor series FQ, FP, FM and FK. The chances are high that you find exactly what you are searching for.
Since more than a decade, the Freiburg–based specialists are supplying speed sensors for the demanding use in electric drive systems for various applications: Material handling, indoor-vehicles, electric fan drives and many others.
All models of these sensor families are equipped with a proven differential-hall technology for safe and reliable detection of rotational speed even in critical electrical and magnetic environmental conditions. The 2-channel design allows not only detection of rotational speed but also the direction of rotation.
Especially in the price-sensitive market of electric drives, users can choose RHEINTACHO sensors matching their needs regarding:
- The required signals
- The necessary protection class for their specific applications
- Interface via cable
- Connector integrated into the sensor body
A wide variety of cable lengths and connector types round off the customization options.
The sensors can be used in a wide range of temperatures (up to +140 °C) due to the housings made of high-quality plastic as well as other constructive measures. The housing material used has exceptional mechanical properties. For example, compression strength and material durability reach values that already allow for substitution of metal housings depending on the respective application. Among other features, the electrical structure provides a very wide range of possible supply voltages and a high level of EMC stability. The Hall element which are used cover a wide frequency range.
The geometric design as flange sensor automatically ensures the proper installation position required for good signal determination.
The most important features at a glance:
- 2-channel differential-hall sensor
- Housing made of high-performance plastic
- Large detection distance possible
- Wide frequency range
- Wide temperature range
Where this success story started: The FK series
The FK series has proven over the last decade as a kind of world-standard for speed detection inside electric drives. And the many copies are to be seen as a grant of honors for an outstanding successful product. The 2-channel sensor design allows for both the speed and direction of rotation to be measured simultaneously using two phase-shifted signals. The temperature resistance and EMC resistance of this sensor achieves top values, thanks to its electronic design and the use of specially chosen materials.
FM series – the all-integrated-sensor
With the FM series, RHEINTACHO added a model, featuring connectors integrated directly into the sensor housing to its sensor portfolio. The sensor is made of a proven high-tech-plastic. The intelligent design, allows for the use of various connectors. And what is even more important to achieve the best possible installation: various connector outlet directions are possible. This is increasing your flexibility of design significantly.
