JAE’s new MX80 seriesJAE’s new MX80 series is a high performance, miniature sealed connector system for the automotive market that combines miniaturization with high performance. Every aspect of the MX80 design has been scrutinized and conventions challenged. The starting point were the terminals inside. The engineers considered many aspects, such as spring geometry, current handling, mechanical locking, wire size, crimp optimization, damage prevention, test probe access, installation and removal, operating temperature range, as well as sealing and vibration performance. Detailed consideration was given to moulding design, material selection and assembly. Tested to automotive specifications USCAR 2/21 and LV214; 2-, 3-, and 4-way inline (wire-to-wire) connectors are available.

Phoenix Contact’s M12 connectorsPhoenix Contact’s M12 connectors are the new standard in automation technology. M12 connectors with a push-pull fast-locking system guarantee secure, tool-free plugging, even in confined spaces and with a high cabling density. Versions with internal locking also enable compact housing designs. Rated to IP65/IP67 (when fully mated) and, like the existing M12 portfolio, push-pull housings are sealed with an O-ring, allowing the connector to be protected against dust, water jets, and temporary water submersion (when fully mated with a cable or connector). Unlike the fully threaded (non-push-pull) solutions on the market that often require the O-ring seal to be added as an additional manufacturing step by the user, these push-pull shells already have the O-ring installed.
