AVX wire-to-wireAVX Corporation has released two new series of wire-to-wire (WTW) connectors that deliver considerable cost and space savings in a broad range of industrial electronics designs: The 9286-200 Series reduced thru-wire connectors and 9286-250 reduced junction box connectors. These latest additions to AVX’s industry-proven 9286 family of poke-home discrete WTW connectors feature an active stainless steel spring contact with mechanical properties that allow them to provide maximum wire retention for 18 – 24AWG solid and stranded wire gauges. Capable of accommodating simple strip-and-poke-home wire insertion and twist-and-pull extraction, which is especially beneficial in field installations, these high-spring-force stainless steel contacts also effectively replace the push-button activation mechanism that traditional two-piece plug-and-socket WTW connectors require for wire insertion and removal, enabling significant cost savings in an array of industrial power and signal applications. Both new 9286 poke-home WTW connectors are rated for 300VAC and operating temperatures spanning -40°C to +130°C, stand a mere 4mm high, and measure a slight 16mm in length. Available in one to six positions, the 9286-200 Series reduced thru-wire connectors measure between 8mm and 24mm in width, and have three current ratings: 3A (24AWG), 5A (22 and 20AWG), and 8A (18AWG). Available in four to eight positions, the 9286-250 reduced junction box connectors measure between 8mm and 16mm in width and have four current ratings: 3A (24AWG), 7A (22AWG), 8A (20AWG), and 9A (18AWG).

Bulgin Buccaneer 4000 seriesBulgin’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 – they offer a choice of solder and crimp contacts and can accommodate cables from 3mm to 7mm in diameter.

C?OAX Connectors Micro BNC seriesCOAX Connectors Ltd introduced a 50-ohm version of its popular Micro BNC series. Initially designed for test equipment applications, these connectors offer the benefits of the traditional bayonet-lock BNC connector in a smaller size. With an operating range from 0 to 6GHz, these connectors could be an ideal alternative to screw-locking 50-ohm series, such as SMA or SMB, and suitable for a wide variety of applications. The simple-to-use quarter-turn bayonet coupling provides a positive lock that is secure from accidental disconnection. In addition to the cable-mounted plugs, COAX offers special configurations for right-angle PCB mounting including the offset-bulkhead version for bulkhead fitting, which saves front-panel space. Some arrangements allow more than four times the number of connectors in the same space as a single BNC.

ERNI MicroStac SMT connector seriesERNI expanded its miniature 0.8mm MicroStac SMT connector series to include anti-magnetic versions with 12-pin (single-row) and 54-pin (dual-row) configurations with a 5mm board-to-board stack height and a 1.5mm effective wipe length. The non-ferrous connectors are designed specifically for medical and instrumentation applications, such as MRI machines, where ferrous materials can be hazardous and degrade test results. The MicroStac components are based on a patented hermaphroditic design that combines male and female connector halves into one solution. The unique design reduces logistic, inventory, and manufacturing costs as the connectors mate and un-mate to themselves. MicroStac products also achieve a high current-carrying capacity. With an ambient temperature of +20°C and current to all contacts, the 12-position MicroStac connector can transfer a derated 2.2A per contact. The contacts are formed through precision stamping. As a result, they offer an extensive cross-section for low ohmic resistance, while at the same time providing a large radiating surface that yields higher current-carrying capabilities than similar competing products. The SMT terminals and the unique design of the MicroStac allow for economical automated assembly. The stability of the miniature connector is facilitated through a tilt-proof contact principle with dual-side positioning of the contact on the PCB. In addition, with its corresponding features of minimal weight (just 0.18g for the six-pin design), co-planarity of <0.1mm, and suction areas integrated in the insulating body for pick-and-place assembly, the MicroStac components are perfectly suited for high-speed manufacturing.

Fischer MiniMax 06 SeriesFischer 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 hybrid BM25 SeriesHirose has developed a small, board-to-FPC (flexible printed circuit) connector designed for battery pack connections in mobile devices. The hybrid BM25 Series connector is rated up to 9A per pin for power contacts and 1A per pin for signal contacts. With a space-saving design that offers a stacking height of only 0.7mm and a depth of 2.6mm, the low-profile BM25 Series delivers twice as much current-carrying capacity in a smaller profile than traditional technologies. Offering contact resistance as low as 5mohms or below for power contacts and 30mohms or below for signal contacts, the BM25 Series provides significant power savings by utilizing a design that minimizes contact resistance. A six-point, highly reliable clip-like contact structure combined with a robust eight-point metal lock provides a mating force that is resistant to intense vibration and drop impact. The BM25 Series also utilizes a metal guide structure that prevents housing damage due to incorrect mating. With a breaking strength of 70N, the metal guide design ensures that if the header and the receptacle should be mated incorrectly, the metal hold-downs would dissipate the force and prevent housing damage. The BM25 Series has an integrally molded header and receptacle that prevents solder wicking; a rated voltage of 30VAC/DC; a power contact resistance of 5mohms maximum and a signal contact resistance of 30mohms maximum; an insulation resistance of 1000Mohms minimum; and an operating temperature of -40°C to +85°C.
