PREMO developed an electromagnetic 3D-coil antenna initially designed for KES applications. The series 3DC09AOI is a three orthogonal coil antenna each of them in the three spatial axes.
Surface mount devices (SMD), also offers side metallization, which allows automatic recognition of soldering process AOI (automatic optical inspection). The pads are gold finished for assuring connectivity between the component and the PCB circuitry in a safer way. Furthermore the contact surface provided by these pads attached to the lateral meniscus formed during the welding process on the metallization side increase in over 25% the mechanical contact between the component and the PCB in relation to the existing products on the market.
The antenna, designed in a low-profile form (10,5×9, 5×3 mm) offers strength since the windings are fully protected by a polymer matrix (vacuum process) for high stability: less than 200ppm expansion and thermal resistance: supports a double lead free reflow (270 ° C – peak).
The 3DC09AOI offers high stability in various temperatures (- 40 ° C-> 85 ° C) in a compact and fully protected format.
The 3DC09AOI is offered in a standard value of L = 14 mH with sensitivity greater than 9 mVpp / App / m @ 20 kHz and maintaining a Q factor of 6; the antenna can be manufactured with different electromagnetic values in each axe according to customer needs.
