Meet the 3DCoil:

Electromagnetic motion tracking systems work by using a low frequency isotropic magnetic field generator (3D emitter) and one or several isotropic 3D magnetic sensors. Emitter and receiver sides need special 3D magnetic coils to generate and receive the magnetic field signals. The low profile 3DCoil design achieves electromagnetic sensitivity isotropy by clever design techniques and fine-tuned windings calculations. By using these, the sensor volume required shrinks to SMT PCB mounted components standards (<3.5mm height).

3DV11AOI – 3D VR Rx sensor 13×11.6×3.45 mm

Low profile 3D magnetic receiver sensor for VR magnetic tracking systems.

• Best size/sensitivity ratio
• SMD solution
• Suitable for AOI
• Best isotropic/size performance
• Inductance range: 2-10mH
• Dimensions: 13×11.6×3.5mm
• Sensitivity (mV/A/m): 11*

* Measured @20kHz 10Vpp

The ultimate goal of virtual reality is achieving total immersion of the subject in a virtual world. With a clever combination of software and hardware, the users are fully captivated by the absolute truth of what they are experiencing with their VR device. The environment in which the user is immersed is so realistic that there is no doubt in their mind that it is, in fact, real. This can only be achieved if all the components of the virtual reality device are of the highest standards, which is what Grupo Premo strives to achieve.

The 3DV11AOI 3dCoil for VR devices’ most prominent quality is it’s compact size and top-notch sensitivity. In fact, it is recognized as having one of the best sensitivity/size ratio on the market, making it a perfect candidate for your VR device. This 3D magnetic receiver sensor is a low profile isotropic magnetic field receiver, which requires no line of sight and has a range of up to 12mV/A/m.

The 3DV11AOI 3dCoil allows for multiple bodies to interact in the same space, allowing for optimum VR/AR experiences. By using low frequencies and long wavelengths, we achieve perfect 6 degrees of freedom and amazing experiences in virtual reality.

You can try the 3Dcoil using our Tx/Rx VR development kit or AR/VR Demo kit.
