BRIEF INFORMATION Angular Position Sensors Single and double sensors Single or redundant sensors High precision due to internal 14 bit resolution High thermal stability and linearity High insensitivity to magnetic fields Zero position can be individually programmed Various connection elements available PRODUCT FEATURES Application The CIPOS -type angular position sensors (contactless inductive position sensors) are designed for many different applications to measure angles accurately and reliably even in tough environments. Their insensitivity to magnetic fields and their high level of temperature stability in particular are the characteristic qualities of the CIPOS technology used in all angular position sensors. Angles are measured inductively using a contactless and thus wear-resistant method. This guarantees a high degree of measurement accuracy throughout the entire life of the sensor. The redundant sensors (double sensors) are specially designed for failure detection, thus improving the reliability of the overall system.

ANGULAR POSITION SENSOR CHARACTERISTIC CURVE The characteristic curves of the turning angle sensor repeat after 12 degrees. The sensor can therefore not only be attached in the position shown, but can also be considerably offset from the 12-degree mark. The behavior of the connected system does not change in any way. The measuring angle range is 6 degrees. If it is exceeded by up to 3 degrees, the output signal remains limited to the measuring range final value. For further exceedance, the next characteristic curve section is run through. The resulting measuring ranges and zero positions can also be obtained from the graphic representation. The grey circle segments reflect the non-measurable angular range. 6º 6º 6º - + Ratiometric output signal U out 1 With 5 V voltage supply U out 1/U s[%] 1 9 8 7 6 5 4 3 2 1-3 3-18 -15-12 -9-6 -3 3 6 9 12 15 18 Winkel Angle [ ] Output signal U out 2 = 1 % U out 1 /U s [%] (opposite curve) Absolute output signal U out 1 with 9-32 V voltage supply U out U out 1[V] 1[V] 5 5 4,5 4 3,5 3 2,5 2 1,5 1,5-3 3-18 -15-12 -9-6 -3 3 6 9 12 15 18 Angle Winkel [ ] Output signal U out 2 = 5 V U out 1 [V] (opposite curve)
FUNCTION Rotor Rotor Induktion Induction Stator Stator Elektronik Electronic system Transmitter coil Spule Empfängerspule Receiver coil Inside the laser-welded polyamide housing (PA66), the rotation of the lever arm is transferred to the rotor and measured by induction. An ASIC (Application Specific Integrated Circuit) accurately computes the rotor position. Various mounting positions are possible thanks to the repeating characteristic curve of the output signal (which depends on the structure of the sensor that is used), which increases the flexibility of the sensor.
