Easy-Handling, Quick-Mating, High-Reliability Connectors

JAE MX72 Series AK2 squib connectorsJAE’s new MX72 Series AK2 squib connectors ensure a fully reliable connection in a single operation. The AK2 type squib (igniter) connector has been adopted as the standard interface for automotive airbag inflators in Europe and North America and use is growing globally. Unlike most AK2 squib connectors that require a CPA (connector position assurance) component to ensure complete mating, the MX72A/MX72B Series connectors eliminate incomplete mating with a spring-operated self-rejection structure that provides positive audible and tactile feedback. This allows for confirmation of complete engagement in a single operation. Therefore, the MX72A/MX72B Series improves workability and reliability of the airbag system by preventing incomplete engagement. Three mis-mating key options, compatible with USCAR and ISO standards, are available in case multiple connectors are on one board. This product is sold only as a cable harness and is not provided as an individual connector.

SV Microwave's new pre-tinned PCB connectorsSV Microwave’s new pre-tinned PCB connectors are available in the company’s proven high-performance, high-density SMP and SMPM series. These SMP/SMPM pre-tinned PCB connectors can withstand up to 1,000 mating cycles and feature a compact, easy-to-install, push-on design. SV Microwave has developed a unique and proprietary method for removing gold in the solder area of its RF connectors. These connectors are designed to work with SV Microwave’s automated de-golding process which mitigates undesirable remnants of gold plating in the solder joint. Excess gold can create a gold-tin compound known as AuSn3. These gold striations in the solder joint are brittle and susceptible to breakage under mechanical stress (shock and vibration). For this reason, designers of high vibration and extreme movement RF PCBs often require there to be a minimal amount of gold in a solder joint, as defined in J-STD-001. SV Microwave’s method plans for gold removal in the design stage, modifying the connector body so it can be fixtured effectively and gold can be thoroughly removed from the solderable area, including nearby areas which may be prone to capillary-effect wicking.

Harwin 101Lok DataMateHarwin has just launched 101Lok, a fast-mate version of its secure, 2mm pitch, Datamate J-Tek cable-to-cable, cable-to-board, and board-to-board connector family. Historically, secure mating has been achieved with the Datamate J-Tek version using jackscrews. New Datamate 101Lok connectors require only a simple ‘quarter turn’ – actually 101 degrees – to ensure complete security of the retention device. 101Lok connectors use specially designed hardware tensioned by a coil spring to reduce the time required to mate the connector halves. This results in faster assembly while ensuring complete security of the retention device. This novel locking feature is also ideally suited to Harwin’s mixed technology Datamate Mix-Tek connectors and the Datamate Trio-Tek range. The spring tensioning also helps resist vibration in rugged environment applications such as aerospace, defense, and motorsports, giving the same level of performance as the existing Datamate J-Tek range.

Greene Tweed Seal-Connect fiber optic portfolioGreene Tweed’s Seal-Connect fiber optic portfolio features FC and ST DRY HP Series connectors. Seal-Connect fiber optic connectors are preferred for applications in which fiber protection and signal clarity cannot be compromised, such as oilfield, aerospace/defense, and underwater ROV systems. FC and ST DRY series connectors maintain signal clarity in temperatures from -55°C to 85°C (-67°F to 185°F) with typical light loss less than 0.5 dB. The FC connectors use a threaded position keyed coupling connection while the ST connectors feature a bayonet twist-lock (j-slot) connection. A precision-machined, corrosion-resistant zirconia ferrule and alignment sleeve connection ensure a reproducible, highly reliable termini alignment every time. When coupled with an adapter or permanent bulkhead feedthrough, connectors form a hermetically sealed connection protected in harsh environments where the assemblies are likely to be submerged in water or subjected to rain, ice, or high humidity, preventing optical fiber degradation.
