Hardware housing, integral blind mate system, integral locking system, float mounts, panel mount clips and board locks. The Scorpion series is the solution to maximize power throughput and minimize space claim. PEM SpotFast Self-Clinching Fasteners Enables Flush Joining of Two Sheets PEM SpotFast self-clinching fasteners enable two sheets to be joined permanently in a flush-attachment connection without protrusions on either side. These alternatives to riveting or spot welding provide solutions to attach two metal sheets too thin to weld, fasten sheets of unequal thicknesses, join dissimilar metals, attach ultra-thin metal sections or join metal sheets to PCB or plastic panels. Their rotational capability offers additional application advantages by allowing the fastener to act as a hardened pivot point. SpotFast fasteners install smooth with the top sheet and flush or sub-flush with the bottom sheet. Unlike rivets that “bulb” during installation, this hardware allows for unobtrusive flush attachment requiring minimal space. Unlike spot welding, a smooth surface is retained for finishing and the fasteners subsequently can be concealed with paints or powder coatings. The SpotFast product family includes Type SF steel fasteners for metal-to-metal attachment, Type SFP precipitation hardened stainless steel fasteners for installation into stainless sheets where corrosion resistance may be required, Type SFW steel fasteners with supplied wave washer for metal-to-metal single point hinging applications, and Type SFK steel fasteners featuring two separate joining profiles allowing attachment of metal sheets to PCB or plastic panels. Standard parts in various head diameters and sizes can be installed in aluminum or steel sheets as thin as 0.030 inches/ 0.8 mm. Modular Power/Signal Connector Maximizes SWaP Reduction Positronic Industries has added an 8.20 mm low-profile version to the Scorpion power/signal connector series. The Scorpion product is unique for three key reasons. First, its modular tool design allows for a nearly limitless variety of customer-defined contact arrangements. Secondly, the molding process yields a one-piece insulator, and thirdly the customer can define the connector width as long as the maximum envelope of 101.00 mm is not exceeded. Due to the modular tooling, customers can achieve optimum size, weight and power by configuring a power/signal connector from a selection of modules. In the low-profile version, the module options include size 12 contacts, size 20 contacts, size 22 contacts and blanks/spacers. Contacts are rated up to 55 amps for size 12, 12 amps for size 20 and 3 amps for size 22 contacts. Contact resistance values are as low as 1 milliohm for standard conductivity contacts and 0.7 milliohms for high conductivity contacts. The blanks/spacers allow the user to space power and signal contacts to tailor creepage and clearance values to meet design criteria. Contact terminations include board-to-board, boardto-cable, cable-to-cable and panel mount options. Additional features/accessories include ventilation slots in the connector 26 ERNI’S MicroSpeed Connector Systems Enable 10 GBps Speed and Blind Mating ERNI has developed the MicroSpeed high-speed board-to-board connector system with a 1.0 mm pitch. The MicroSpeed connector system is capable of speeds up to 10 Gbps and is available in mezzanine, right angle and coplanar configurations. The open pin field design of the MicroSpeed connector can accommodate differential or single-ended signals, while maintaining maximum performance speed. An added security measure for system integration is afforded by the generous mis-mating allowances of the unique contact design, which provides a longitudinal misalignment tolerance of +/- 0.7 mm and angular misalignment tolerance of up to 4º. The MicroSpeed connector system yields excellent RF signal characteristics. The rows of signal pins in the board-to-board configuration are shielded on the perimeter of the connector body and can be optimized for high impedance signal transmissions. The MicroSpeed connector system is also available in blind mating versions for demanding applications where ruggedness and flexibility are necessary. Guide elements in the plug side and improved lead-in for receptacle mating insures proper alignment and secure connections on the first attempt. Microspeed connectors are available in both SMT and SMT/ THR termination styles. The SMT/THR style uses traditional SMT contacts but THR for the perimeter shield, which provides added board retention/strain relief should the application require high stack heights, or if the connector is integrated within a system of heavy daughter cards. The connector body incorporates polarized board locating pegs for easy, error-free placement and processing. ERNI leads are formed as an integral part of the stamping die, as opposed to other leads that are bent and stamped for SMT termination. This process guarantees coplanarity of 0.1 mm and virtually eliminates processing defects. Conec’s Flange Mounted USB 2.0 Connectors Deliver Reliable Protection Conec has expanded its bayonet locking, IP67rated industrial USB 2.0 connector series utilizes a four hole flange mount nickel plated die-cast housing. The waterresistant USB 2.0 connectors can be mounted on the front or rear side of enclosure panels up to 3.2 mm thick. The interface of the USB 2.0 connector meets IP67-rating requirements when mated or covered with a protective cap. The addition of four-hole mounting provides extra protection against harsh environment elements, while facilitating easier connections for industrial applications. The USB 2.0 connector also features M28 threads as an ad- March/April 2013 www.ElectronicsProtectionMagazine.com http://www.ElectronicsProtectionMagazine.com
