Three axis magnetic sensor for magnetic tracking sensor systems. Very good performance/size ratio, with isotropic response. Used as receiver in VR/AR applications (gaming, etc.) and motion capture applications. Very low latency compared with other motion tracking technologies.
This chart is a reference guide for the most common required values at working frequency of 20kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales department for any inquiry.

A wide range of configuration possibilities
PREMO biggest competitive advantage is the short time-to-market performance when developing a custom-made solution according to customer specifics.
A wide variety of EM sensors can be designed to meet AR/VR systems requirements. From cube configurations to low-profile configurations, and from lower to higher sensitivities, the range of possibilities is very wide:
• Shapes (i.e. rectangular, quasi-cub, ultralow-profile)
• Inductance: Tx (20μH – 2mH), Rx(300μH – 7mH)
• Operation frequency (3 – 300kHz)
• Standard cables to male/female connector
• FPC connection
• Over-Molded (low pressure molding)
