## Overview

The OptiMate Cable O-40 is a premium weatherproof SAE socket with a 40-inch, 18AWG cable rated for extreme cold down to -40°C. Designed for panel mounting in an 18mm hole, it supports up to 5 Amps and offers a reliable, waterproof connection ideal for motorcycles, boats, and outdoor charging setups. Compatible with popular bike brands and built for rugged, permanent installation, it’s the go-to accessory for professionals demanding durability and seamless power access in any weather.

## Description

New in cables is the OptiMate Cable O-40 M18 panel-mounted SAE socket with 100cm / 40″ cable that terminates in an SAE connector. The 18AWG / 0.82mm2 cable is rated at –40°C/°F, ideal for permanent mounting on a vehicle that is also used in cold weather. The socket can be used as a drop-in replacement for more expensive DIN (‘Hella’) socket & plug system used on BMW, Triumph, Victory and now on some Ducati motorcycles. Fitment to the battery requires a battery lead that terminates in a SAE connector, like the OptiMate O-01 weatherproof battery lead.

Review: I wanted a suitable connector to provide a removable solar connection to a project I was building and this was just the job. Provides a nice reliable and waterproof connection. Hasn't given me any problems so far. I would imagine it would work well providing a nice quick access charger connection point on bikes, boats etc.
Review: Ho usato il prodotto per collegare un ecoscandaglio Lawrence alla scatola impermeabile.

乗ってるバイクが、カバーを六角で外すとそこにSAEコネクタがぶら下がってるタイプなので、カバーに穴開けてこれを付けて工具レスで充電出来るようにしました。 ネジ側じゃない方をぶった切って延長してフューズかましてバッテリーに直で付けてます。 延長もSAEで出来ますが、太くなるし、延長コードもまずジャストサイズは無いでしょうから、ねじ込み側のコネクタのみの商品があってもいいように思います。 ネジはプラ製ですが結構しっかり閉められますし、ゴム製キャップも脱着容易でちぎれそうな感じもしません。 他に、テックメイトのハーネスには許容電流違いがあるので、そこがめんどくさいです。
