OptiMate CABLE O-20 Weatherproof SAE socket, front panel mount

The OptiMate O-20-2 is a heavy-duty, weatherproof front panel mount extension cable designed to create an accessible bulkhead charging or power point on your vehicle, tank bag, or hard case. Engineered specifically for situations where there is little to no access behind the bulkhead, this innovative socket mount can be installed entirely from the front. It cleanly bridges an internal battery hookup to a flush, exterior-facing standard 2-pin SAE port, giving you a clean connection point without the hassle of unmanaged dangling wires.

Features and Benefits

• Convenient front-mount installation — Specially designed for easy exterior fastening into a standard 1" (Ø25 mm) drilled hole, allowing you to secure the bulkhead mount from the front side when rear access is restricted.

• Secure rubber expander bushing — Features an innovative rubber expander locking mechanism that swells inside the drilled mounting hole as it is tightened, ensuring a vibration-resistant, watertight friction fit.

• Extended routing range — The generous 120 cm (48″) total cable length delivers plenty of slack to cleanly route power from deeply recessed internal batteries or electronics modules out to an exterior body panel.

• Universal SAE pass-through — Utilizes an industry-standard 2-pin SAE connector on both ends, serving as a perfect weatherproof bridge for smart battery chargers, maintainers, solar panels, or on-board 12V accessories.

• High-capacity current delivery — Safely handles a continuous 10A current average and up to a 13A maximum threshold, minimizing voltage drop across the extended cable run.

• 16 AWG / 1.31 mm² cable — Heavy-duty premium copper strands wrapped in extra-thick SPT-2W insulation to maximize structural durability and provide high abrasion resistance against panel edges.

• Weatherproof inline sealing system — Features an integrated rubber sealing cap and protective shroud on the exterior socket to entirely lock out moisture, driving rain, mud, and dust when not in use.

• Rated for –40 °C/°F — Constructed from ultra-premium materials designed to withstand severe weather environments, ensuring the thick insulation remains fully pliable and crack-resistant even in deep sub-zero freezing conditions.
