MikroTik CA493U Internal Case – Black Networking Enclosure

MikroTik CA493 is an aluminium indoor enclosure for the RouterBOARD RB493 platform, designed for interior installations where mechanical protection, RF antenna connector access and compatibility with various miniPCI card heights are simultaneous requirements. Commonly used in indoor multi-radio wireless deployments requiring external antenna connectors, it provides a professional mounting solution for RB493 boards in office and technical environments.

The enclosure features three openings for N-female Bulkhead connectors or AC/SWI swivel antennas, enabling external antenna connection for configurations with one to three wireless radios without additional modifications. The updated revision is slightly taller than previous versions, ensuring compatibility with a wider range of taller miniPCI card models — a practical advantage for integrators working with varied hardware configurations. Black aluminium construction provides mechanical protection superior to plastic enclosures and a professional appearance suited to visible installations.

CA493 is exclusively compatible with the RB493 series, ensuring a precise fit for all board ports and connectors without modifications. The aluminium construction contributes passive heat dissipation from active miniPCI cards, helping maintain operating temperatures within safe limits during continuous operation. The black finish and aluminium material offer a discreet, professional look well suited for offices, equipment rooms and indoor technical spaces.

Recommended for indoor RB493 series deployments with multi-radio configurations requiring external N-female antenna connectors, for environments where compatibility with taller miniPCI cards is important for specific hardware configurations, for offices and technical spaces where the professional appearance of an aluminium enclosure matters, and for integrators standardizing indoor RB493 installations with a dedicated enclosure providing full RF connector access.
