The MS3106R10SL-3S is a 3-contact military standard Circular Connector with silver-plated copper contacts, straight plug, lightweight and environment-resistant, 10SL-3 insert arrangement and socket contact type. Shell components are fabricated from high grade aluminium alloy. All components have the standard electrically conductive cadmium-plated finish with an olive drab chromate after-treatment for corrosion resistance. Resilient neoprene inserts provide an outstanding moisture barrier, maximum vibration resistance and high dielectric strength. This connector represents well-proven electrical capability at an acceptable cost for most equipment where durability is important. MIL-C-5015 features threaded coupling, single key and keyway polarization representing maximum simplicity in design. Suitable for ordnance and shipboard installation.
