Easy / fast processing Interconnect Bulgin's Waterproof Miniature USB Connector A new Miniature USB connector joins Bulgin's Buccaneer family of waterproof data connectors. USB is a well established PC interface using the standard 'A' and 'B' type connectors, but as the trend for smaller equipment continues naturally smaller connectors are required. The Miniature USB is very familiar to digital camera users but is also applicable for use on any equipment where the full functionality of the USB interface is required. In common with others in the Buccaneer range, Bulgin's new 5 pole miniature USB connector is dust and waterproof to IP68, when mated, and provides USB V2.0 performance up to 480Mbs. The pre-wired cables, PX0441 and PX0442, are available in 2, 3 and 4.5m lengths with a sealed Mini 'B' type USB connector paired with either standard or miniature 'A' type USB. These will cater for most applications. The panel mounted Mini 'B' connector is available for front-of-panel, PX0443, or rear-of-panel mounting with either PC pins, PX0446 or pre-wired, PX0447, with a short length of cable terminated with a PCB header. contact : Chris Viveiros Chris.Viveiros@avnet.co.za Electromechanical American Zettler's AZ2501 Series - Stand-up Latching Power Relay Micros Freescale's High Performance with Cool Possibilities MC9S08QD4 MCU for DC Fans and More AZ2501 Series relay, the stand-up PC mount variation to their AZ2500 Latching Power Relay. The AZ2501 has the capacity to handle heavy loads up to 13,850 VA, 50 Amps @ 277 VAC making it ideal for applications such as HVAC-R, UPS systems, lighting controls, industrial heating, and spa controls. AZ2501 features include: dielectric strength of 4000 Vrms contact to coil, single or dual coil latching, a 50 millisecond pulse to "Set" or "Reset", an optional manual switch, an option PCB retaining stud, and available epoxy sealing (excluding versions with manual switch). contact : Rudi Opperman Rudi.Opperman@avnet.co.za The 8-bit MC9S08QD4 (QD4) microcontroller expands the low-end capabilities of Freescale's Controller Continuum. The QD4 offers enhanced functionality and flexibility while maintaining pin compatibility with the ultra-low-end KA2 family and the highly integrated QG8 family of controllers. The QD4 incorporates a high-performance 4-channel, 10-bit analog-to-digital converter (ADC), which makes it an ideal solution for DC cooling fans in computer applications, low power supplies and telecommunications equipment. contact : Dennis Walden Dennis.Walden@avnet.co.za The diameter over the coupling ring of the cable connector is just 19mm and the screw coupling provides a secure, proven locking system. Mini USB Buccaneer will find many applications within smaller peripherals or where panel space is at a premium and, as with all Bulgin products, is fully RoHS compliant. contact : Chris Viveiros Chris.Viveiros@avnet.co.za |
