The Icom OPC-2522L is an 8-pin right-angle (L-type) microphone adapter cable manufactured by Icom Inc. in Japan. Purpose-built for space-critical marine installations, the OPC-2522L connects between an 8-pin speaker microphone (such as the HM-205RB) and Icom fixed-mount VHF transceivers (including the IC-M510, IC-M510EVO, IC-M605, and IC-M430 series).

By converting a standard straight-plug microphone connection into a low-profile 90-degree right-angle interface, the cable significantly reduces front-panel depth requirements on crowded bridge consoles and enclosed helm stations. It prevents cable bend strain, protects internal transceiver jack pins from mechanical levering forces, and provides watertight, heavy-duty 8-pin threaded coupling for harsh offshore conditions.

Key Features:
• 90-Degree L-Type Form Factor: Diverts microphone cable routing downward or sideways, conserving console space in tight wheelhouses.
• Connector Protection & Strain Relief: Prevents bending fatigue on microphone cords and eliminates mechanical strain on the radio’s mic jack.
• Watertight Marine Coupling: Fitted with 8-pin threaded waterproof connectors designed for saltwater environments.
• Direct System Compatibility: Engineered specifically for Icom HM-205RB speaker microphones and IC-M510/M605/M430 series VHF transceivers.
