Coaxial adapter MikroTik CA-NM-RSM N male to RPSMA male

MikroTik CA-NM-RSM is a coaxial adapter that converts an N male connector to an RPSMA male connector. Designed for RF and antenna connections, it enables compatibility between devices and cables with different connector types while preserving signal integrity and mechanical fit. The adapter is intended for use in networking and wireless equipment setups where secure, low-loss connections between antennas, radios and test instruments are required.

Advantages

The adapter provides a straightforward mechanical conversion from an N male interface to an RPSMA male interface without requiring cable replacement or permanent modification. Its compact, durable construction helps maintain impedance matching and minimize reflections in RF paths. The connector surfaces are engineered for repeated mating cycles and stable electrical contact, ensuring consistent performance in both permanent and temporary installations.

Suitable for

• Connecting antennas or pigtails with N female sockets to devices with RPSMA female ports
• Field testing and lab measurements where connector conversion is needed
• Wireless access points, routers and radio modules with differing connector types
• Temporary or permanent RF link assemblies in networking installations

Key specifications

• Connector type (input): N male
• Connector type (output): RPSMA male
• Application area: RF/antenna connections for wireless networking and test equipment
• Impedance: 50 ohm typical for coaxial RF adapters
• Construction: compact metal body suitable for indoor and sheltered outdoor use

How to use

Select the adapter when you need to join a cable or antenna terminated with an N female connector to equipment that accepts an RPSMA female connector. Align the N male end with the corresponding N female socket and engage the coupling mechanism until seated. Insert the RPSMA male end into the RPSMA female port and push until the locking feature is engaged. Ensure connections are clean and free of debris before mating to reduce insertion loss and prevent damage. Avoid excessive torque when tightening; hand-tighten or use appropriate tools only as recommended for your specific connectors and cables.

Usage recommendations

For best RF performance, use the adapter in 50 ohm systems and limit the number of successive adapters or adapters plus long cable assemblies to reduce potential insertion loss and reflections. Store the adapter in a dry environment when not in use and protect connector ends with caps to prevent contamination. When used outdoors, employ appropriate weatherproofing measures at the connection point to prevent moisture ingress.
