Microfoonkoppeling alan elektronik Midland NC 526 4-polig voor 4-polige stekker en bus

Microphone coupling by alan elektronik designed for Midland NC 526 offers a 4‑pole connection compatible with standard 4‑pole plugs and sockets. This coupling provides a stable electrical link between a microphone and radio transceiver, maintaining signal continuity and ensuring reliable contact across all four conductors. The compact, purpose‑built part is intended for use in communication equipment repairs and microphone replacements where a four‑pole interface is required; it is suitable for both workshop servicing and on‑site field maintenance.

Advantages

The 4‑pole design preserves individual signal paths and ground reference, reducing cross‑talk and contact resistance. Its mechanical fit matches common 4‑pole connectors used in Midland NC 526 compatible systems, enabling straightforward replacement without modification. Manufactured for durability, the coupling withstands repeated insertions and removals while maintaining electrical performance. Installation is simple and requires no special tools beyond basic hand tools typically available in radio repair environments.

Suitable for

• Replacement of damaged or worn 4‑pole microphone couplings in radio handsets
• Repair and maintenance of Midland NC 526 compatible communication equipment
• Field servicing where a compact, serviceable 4‑pole link is needed
• Workshop retrofits when restoring microphone-to-radio electrical connections

Key specifications

• Connector type: 4‑pole coupling compatible with 4‑pole plug and socket
• Function: provides electrical connection for microphone signals and ground
• Mechanical form: compact inline coupling suitable for handset cables
• Durability: rated for repeated mating cycles typical of communication connectors
• Environment: intended for indoor workshop use and portable field repairs

How to use

Disconnect power from the radio transceiver before replacing the coupling. Align the 4‑pole plug with the coupling’s receptacle and insert until a positive mechanical engagement is felt. If the coupling is being installed inline with cable ends, strip and prepare conductor ends according to standard radio wiring practices, then mate the corresponding poles in correct order to preserve signal assignments. After installation, verify continuity of all four conductors and test microphone operation at low volume before returning the equipment to normal service.

Recommendations

Use basic hand tools for installation and avoid excessive force when mating connectors. Check conductor polarity and insulation, and perform a continuity check after replacement. Store spare couplings in a dry environment to prevent corrosion of contact surfaces.
