Hardware Anderson Power Products Introduces the Saf-D-Grid Ultra Short Receptacle Anderson Power Products has released the Saf-D-Grid, which builds on the proven contact technology used in SB and Powerpole connectors by offering features required in 380 VDC to 400 VDC power distribution systems. Saf-D-Grid meets international safety requirements for hazardous, low voltage applications per UL1977 and IEC 61984, as well as touch safety requirements of UL60950 and IEC60950. The Saf-D-Grid is size compatible with the IEC 320 C13 and C14 AC connection system standard 19.9 mm by 26.8 mm panel cut out. It is the only connector system this size that is UL rated for disconnect of a 400 VDC, 20 amp load. The Ultra Short Receptacle minimizes space requirements within the device and enables solder termination to wire. Offering a connector capable of safe disconnect of 400 VDC, 20 A loads requires the combination of several features. Saf-D-Grid is touch safe on both plug and receptacle sides to protect the user from capacitance in the line. Proper voltage clearance and DC arc protection are achieved through unique geometries, which minimize the severity and duration of DC arc flash while shielding the operator. Saf-D-Grid also enables greater power density by allowing up to 40 A and 600 V DC or AC within the same space of the IEC 320 C13 and C14 system that is limited to 10A and 250 VAC. This allows the use of Saf-D-Grid in AC systems that require more power by increasing the wattage capability within the existing connector space. Reell's PolyTorq Technology Expands Capabilities For Hinge and Torque Insert Applications Reell's PolyTorq torquegenerating technology has introduced performance and design capabilities to advance a wide range of hinge and torque insert applications. This technology adds to Reell's portfolio of torque-generating solutions engineered to optimize smallpackage motion control applications. PolyTorq technology effectively generates torque for hinges or torque inserts by interfacing an engineered thermoplastic with either a shaft or a tube. The technology can be specified to simplify designs by enabling complete hinges or torque inserts to consist of only two components, provide robust and durable motion control solutions, and/or allow for customized package size, geometry and torque profile requirements. Reell hinges and torque inserts benefiting from PolyTorq technology will be chemically inert to enable torque to withstand harsh environments and external contaminants, suiting outdoor applications. Variable torque can be achieved as a function of angle with the capability to realize multiple detent positions and complex torque profiles. Torque will perform consistently over a long life; the typical need for grease is eliminated to promote "clean and green" operation without potential grease-loss failures and the technology imparts a viscous damping function without oil to control speed and prevent components from "slamming" shut 28 or opening under variable load. PolyTorq technology joins Reell's ReellTorq clip technology, which was developed for hinges and torque inserts to enhance smooth and consistent action, extend service life and promote low differential between static and dynamic torque. Both technologies can be tailored to meet particular application demands. Gore Introduces new 2.92 mm Right-Angle Connector for Spaceflight Applications The low-profile right-angle connector (ZQA) from W. L. Gore & Associates, Inc. features a nonbifurcated swept contact design for use with low-loss microwave coaxial cable qualified for 32 GHz spaceflight applications. Traditional box right-angle connectors are often associated with poor VSWR (voltage standing wave ratio) performance, particularly at frequencies approaching 18 GHz. This is because many box rightangle designs employ a bifurcated (two-part) internal contact. While the bifurcated configuration allows for easy assembly and low cost, its shape does not lend itself to good internal impedance control or to a robust solder connection. Gore's ZQA connector incorporates the physical advantages of the box right-angle designs ( i.e., low profile and compact size) while maintaining electrical performance comparable with conventional straight connectors. Gore replaced the two-piece bifurcated concept with an internal swept right-angle configuration. The ZQA provides a robust design with added impedance control, maintaining a low reflection path as the signal transitions from cable through connector. As a 2.92 mm instrument grade connector, the ZQA adheres to IEEE 287 standards for precision coaxial connectors with respect to inner conductor, outer conductor and contact height dimensions. As with other instrument grade connectors, the ZQA uses dielectric support at its interface, making the ZQA durable while still providing overall electrical performance and intermateability with SMA, 3.5 mm, and 2.92 mm air interface connector types without concern of adverse electrical or mechanical effects. Multiple Mounting Options for Cooling Units Accommodates Wider Range of Installations EIC Solutions, Inc. now offers multiple mounting options for its thermoelectric air conditioners. Different mounting options make it easier for designers and end users to meet varying installation space requirements. The standard through-mount option assures optimum airflow, which promotes efficient cooling of cabinet contents. In this mounting mode, the cold side of the air conditioner protrudes into the enclosure about 3.5 inches. Through-mounting is well suited as long as the equipment housed in the enclosure allows enough clearance for the air conditioner. However, if there is no room in the enclosure interior, an extension frame mount is now available, which creates an alcove in the cabinet panel. The cooling unit installs in the extension frame in the same November/December 2013 www.ElectronicsProtectionMagazine.com http://www.ElectronicsProtectionMagazine.com
