SB Family Industrial Connectors
Anderson Logo

Anderson Power Products SB® battery connectors are available in several sizes: 50 amp, 175 amp, and 350 amp, which are the most popular. We stock many colors, such as yellow 12 volt, orange 18 volt, red 24 volt, gray 36 volt, blue 48 volt, green 72 volt, and black 80 volt. Each color will connect only with a connector of the same color and size.

Usually, the 50 amp connectors connect to small-medium array connections (parts of larger systems) and small power and battery connections. The 175 and 350 amp units connect to larger batteries and large arrays. Some inverter connections may use these as well.

How to attach your SB® connector

Crimping

Use a crimping tool. It compresses the contact barrel tightly around the cable wires so that all of them are pressed tightly against each other and the inside wall of the contact barrel. This requires that the stripped cable be inserted all the way into the barrel of the contact, and that the contact point is centered in the crimping tool.

We do offer a crimping tool on our website.

Soldering

If you don't have a crimping tool, the alternative is to solder all cable strands within the contact barrel. The right proportion of solder is essential if this procedure is used. Use a quality solder in wire form with a rosin flux core. The cable strands should be separately fluxed with rosin paste, and the contact should be held in a vise with the barrel end facing up. Apply heat to the outside of the barrel while the solder flows in beside the wire strands.
