Irrigation Pump

An irrigation pump is suitable for dental applications that require frequent tube changes. The 313D aseptic pump head provides continuous tubing and has flow rates from 0.25 to 3000 ml/min. Options include an open indicator switch, fixed or variable tube clamps, and private labeling. The sanitary pumps have no valves or seals and can run without dry damage. Extension heads are available to stack up to six pump heads on a single drive. Gearmotor drives come in ac, dc, stepper motor, and brushless dc configurations. The pump can be customized to work with any pump-grade tubing. The company makes tubing in USP Class VI–approved materials. Tube materials are available in 12 standard sizes to match flow range, pressure, and suction requirements. Watson-Marlow Bredel Inc., Wilmington, MA.

Coolant and Lubricant Mixing Stations

For medical device manufacturers with strict requirements for metals, such as those that machine titanium for implants, a series of mixing stations blend and dispense cutting and forming fluids. Manufacturers can use the stations to automate the mixing and supply of fluids and lubricants to one or more metal-forming or machining stations. Standard features on the central supply mixing station include a programmable logic controller, adjustable outlet pressure, multiple alarm conditions, a 10-µm water filter, and removable enclosure. The station produces concentrations ranging from 0.5 to 37% depending on viscosity, and delivers up to 3 gal of fluid per minute. A stainless-steel enclosure is optional on the manual mixing station, which has a maximum concentration of 17% and dispenses up to 7 gal/min. UNIST Inc., Grand Rapids, MI.

Device-Networking Coprocessors

A family of turnkey networking-coprocessor system-on-chip (SoC) devices gives OEMs an option for embedding serial-to-Ethernet connectivity and Web services in high-volume, cost-sensitive products with microcontrollers so that they can be managed remotely over the Internet. Incorporating royalty-free application and network firmware, the small DeviceLinx XChip SoCs help OEMs get new products to market quickly because virtually no additional coding and no licensing commitment is necessary, according to the company. As dedicated networking coprocessors, these single-chip Ethernet Web servers enable host microcontrollers that have limited functionality to operate at maximum capacity without the burden of network processing overhead. Constructed using the industry-standard CMOS process, the devices are highly integrated x86-class processors that include a built-in Ethernet MAC and 10–100 PHY, 256-Kbyte zero-wait-state SRAM, up to 11 general-purpose I/Os, and a high-performance serial UART in a 12 × 12-mm 184-BGA RoHS-compliant package. The family includes an embedded device gateway coprocessor, an embedded device server coprocessor, and an embedded programmable device server coprocessor. Lantronix Inc., Irvine, CA.

Press-Fit Pin Connectors

A renovated line of smooth-sliding, fast-holding press-fit electronic connectors features compliant pin technology that allows solderless mating of PCBs. The lead-free OEM devices provide connections that withstand thermal shock, vibration, and humidity and, with the close-tolerance milling of the rugged pins, now slide smoothly into plated through-holes. A design that limits the insertion force necessary for snug connection enables connectors with numerous pins to be inserted easily while also eliminating the scraping of particulate debris from the through-holes. Available in standard and custom versions, the connectors can be used in delicate devices and harsh environments. They can be reinserted reliably for more than a thousand cycles. The connectors are specified to deliver dc to 10 GHz with pin-to-pin capacitance as low as 1 pF, inductance as low as 2 nH, and connection resistance below 10 mŮ. Onanon Inc., Milpitas, CA.
