CIPOS® technology

Contactless Inductive POsition Sensor technology - when it comes to precise position measurement. With CIPOS^®, HELLA utilizes an innovative technology that offers the highest measurement accuracy. Find out in which products it is installed and what advantages it offers you here.

What does CIPOS^® mean?

In the automotive and commercial vehicle sector, robust and reliable position sensors are of crucial importance. CIPOS^® technology, which stands for Contactless Inductive Position Sensor, offers exactly these features. Products equipped with CIPOS^® are characterized by high reliability, fast measurement speed, precise accuracy and excellent temperature stability.

Sensors and actuators based on CIPOS^® technology are impervious to vibration and offer mechanical robustness as well as resistance to chemicals. The main difference to other sensor technologies such as Hall or magnetoresistive sensors is that CIPOS^® is insensitive to interfering magnetic fields. This guarantees reliable position measurement, as no magnets are used. Linear and rotary positions are measured purely inductively. Thanks to the combination of an inductive measuring principle and a special rotor shape, CIPOS® sensors deliver precise and reliable results even when measuring the smallest angles.

Another major advantage of CIPOS^® technology is the multi-channel structure, which enables redundant measurements. This structure ensures a high level of fail-safety, the so-called "fail operational". This is particularly relevant for safety-critical applications such as electronic steering and accelerator pedals, where signal stability and fail-safe operation are of great importance. Configurations with six or more channels are possible and offer additional safety and reliability.

CIPOS^® technology therefore represents an innovative solution for position sensing and offers numerous advantages over conventional sensor technologies.

In which products is the CIPOS^® technology (contactless inductive position sensor) installed?

CIPOS^® technology is used in accelerator pedals as well as in universal angular sensors. But also in actuators, such as the rotary, smart actuators for 360° angles (smart URA); Rotary smart actuators for high temperatures (turbocharger actuators) and rotary actuators for high temperatures (waste gate actuators) are equipped with CIPOS^® technology. CIPOS^® technology enables extremely precise and reliable position measurements and is therefore used in a wide range of applications.

In cooling circuits in various vehicle segments, CIPOS^® actuators control the coolant valve and thus enable a variable coolant flow. This leads to a particularly precise regulation of heat volumes, which is crucial for the optimal performance and longevity of the vehicles. Contactless measurement also makes CIPOS^® sensors indispensable in accelerator pedals. The electrical output signal is obtained using the CIPOS^® measuring principle, which enables precise and wear-free detection of the pedal position. 
But that's not all: CIPOS^® sensors measure angles precisely and reliably inductively. Whether throttle position, vehicle level or the position of moving elements – the applications are diverse and impressive. 
Other actuators use this technology to ensure that seeds are precisely metered and singulated. Sensors with CIPOS on the combine harvester also measure the position of the mower when l it is lowered, raised or locked. On a concrete pump, on the other hand, they determine the position of the boom arm. If sensors are installed on the axle, wheel angle and wheel level can be precisely determined.
