From RS PRO a fantastic series of circular In-line cable mount connectors made from quality materials, designed for use in harsh environments and offer excellent resistance to corrosion. These cable mount connectors are available as male pins or female receptacles rated from 125V to 250V, and 3A to 13A current rating. These products are ideal for making your own customised connection for indoor/outdoor applications where a secure waterproof connection is required.

In-line circular connectors are coupling devices that are quick and easy to install, and the job can be carried out by both engineers or DIY enthusiasts. Each element should be assembled in a specific order to retain the integrity of the IP67 rating and a professional install. Wire cable and diameter are vital components so prior to soldering ensure the correct wire gauge (AWG) is being used in accordance with the application standard.

The RS PRO ST1211 series are In-line circular connectors available with a plug or socket type connection, constructed to ensure high-performance with a watertight connection. They are high-voltage power connectors that have a housing-made zinc alloy with a black nickel-plated shell, brass contacts with gold plating, and a threaded coupling that ensures a secure connection.
