Bulgin’s Buccaneer 4000 Series builds on the success of the Buccaneer 6000 and 7000 Series of quick-locking connectors, as the connectors provide the same twist-lock coupling and “fit-and-forget” connectivity in a more compact format. The series provides excellent sealing characteristics to IP66, IP68, and IP69K standards to ensure true environmental protection in harsh conditions as well as to withstand vibrations, shocks, and corrosion to EN/IEC 60068 requirements. Each unit has a UV-resistant UL94-V0 flammability-rated plastic body equipped with the twist-locking mechanism, allowing a secure connection without the need for specialist tools. Currently available in three-, eight-, and 12-pole configurations rated up to 13A, 600V – plus a micro-B USB data connector – it offers a choice of solder and crimp contacts and can accommodate cables from 3mm to 7mm in diameter.
Fischer Connectors launched an even smaller ultraminiature connector, MiniMax 06, as an extension of its miniature high-density product range, the Fischer MiniMax Series. The MiniMax 06 connector can include up to 12 power and signal contacts in a footprint of only 10mm. This corresponds to a density factor of 0.83 – a unique technological feature for a connector with standard 0.5mm contacts. The MiniMax 06 also includes a new unique configuration with two signal and two high-power 1.3mm contacts for applications that require 10A or more power, doubling the standard 5A current rating of the existing MiniMax product line. Also available as a pre-cabled solution, MiniMax 06 is ideally suited for handheld or body-worn applications when space is limited. Tested for high-speed protocols such as HDMI and data transfer up to 10Gb/s, the series also addresses the growing market need for higher data transmission rates. With its new smaller version, the Fischer MiniMax Series now comes in two sizes, 06 and 08, with receptacles of 10mm and 12mm footprints respectively. Configurations range from four to 24 contacts.
Hirose has designed a small circular power connector with a patented push-and-pull lock for rugged applications. The IP68-rated waterproof HR30 Series connector features a lightweight plastic shell that is corrosion-resistant. When the connector is mated, the unique waterproof gasket design prevents water intrusion, even while submerged in water at two meters for 14 days. Well suited to power a wide variety of applications in outdoor and other harsh environments, the HR30 Series simplifies field assembly via an innovative cable-clamping method: The connector quickly clamps and seals automatically by tightening the rear housing over the cable, compressing the seal for waterproof operation. The push-on/pull-off mating ensures a secure connection via a sleeve-locking mechanism. The plug and jack are designed for overmolding, which provides design flexibility and customization. Available in three, six, 10, and 12 positions, the HR30 Series is offered in plug, receptacle, and jack-and-cap versions; has an operating temperature range of -40˚C to + 105˚C; a contact resistance of 5m to 30 ohms maximum at 1A; and an insulation resistance of 1000Mohms maximum at 100V DC.

The radically simplified mounting of Lumberg’s new 360-degree shielded screw-type circular connector addresses assembly requirements in the field as well as those of manufacturers targeting high volumes for pre-assembly. Lumberg’s next-generation circular DIN connectors feature a highly innovative shielding mechanism on the inside of the casing, which has been registered for patent approval and results in a connector composed of fewer individual parts. This facilitates a much faster assembly process, whether soldering or crimping the cable to the connector’s components. The time-intensive steps of stripping, expanding, shortening, and applying a shielding braid for comparable connectors becomes completely redundant here; manufacturing can be completed in 50% of the time currently needed for conventional connectors. It is salt-spray-, dust-, and UV-ray-resistant and a special vibration protector fitted into the metal casing – also registered for patent approval – acts as an added security feature by preventing loosening of the screwed connection.
Murrelektronik‘s IP67-rated industrial M12 connectors are ideal for use in industrial Ethernet applications. The X-coded M12 connector transfers large quantities of data while the Y-coded M12 connector transfers both data and power. Additionally, Murrelektronik’s X-coded M12 cordsets facilitate error-free, high-speed data transfer at speeds of up to 10Gb/s. The connector design safely separates the four data pairs from each other while the internal shielding protects the cable from external interference. Meanwhile, Murrelektronik’s Y-coded M12 cordsets transfer data and power in one connector. The connector separates the four power transfer contacts from the four signal contacts in the pin arrangement, making it possible to transfer up to 100Mb/s of data while providing 2 x 6A power.
The ODU MINI-SNAP can transmit power, signal, data, or media, in a robust metal housing that provides easy handling. The push-pull locking system prevents the unintentional release of the connection: Once mated, the ODU MINI-SNAP locks itself into the receptacle and can no longer be separated by just pulling on the cable. The plug can, however, be de-mated easily and quickly from the receptacle when the outer sleeve is pulled back, which allows for blind mating in difficult-to-reach places. With high contact density and a long service life of more than 5,000 mating cycles, the ODU MINI-SNAP is available in up to six sizes, three basic keyings, and varied designs. It can be used in a wide range of applications, such as medical technology, measurement and testing technology, military and security technology, industrial electronics, and energy technology.
