Push-to-Connect Fittings
Posted in Electronics & Computers, Electronics, Products, MDB on Wednesday, 01 June 2011
NewAge Industries (Southampton, PA) offers Newloc® push-to-connect fittings in acetal copolymer and brass. Both allow quick connections to rigid and semi-rigid tubing such as nylon, polypropylene, and polyethylene. Typical applications include pneumatic control systems, robotics, instrumentation, and chemical lines. The fittings offer leak-proof connections with no flow restrictions, as well as a full vacuum rating (29.9 in/Hg). The plastic (acetal) Newlocs are suitable for pneumatics, while the brass Newlocs handle temperatures up to 200 °F.

Medical Desktop Power Supplies
Posted in Electronics & Computers, Electronics, Products, MDB on Wednesday, 01 June 2011
Power Partners (Hudson, MA) has introduced the PPWAMD250 Series of medical desktop power supplies, featuring 250 Watts of power in a compact 7.42" × 4.1" × 2.36" package. The series is approved to UL60601-1, CSA22.2 No. 601.1, and EN60601-1 medical standards and complies with EN55011/FCC Class B radiated and conducted EMI standards. With no load standby power of ≤0.5W and average efficiency of ≥87%, the units are in compliance with Efficiency Level V requirements, and RoHS compliant. Operating temperature is 0 °C to 50 °C. No minimum load is required while still maintaining 5% tolerance throughout the full load range.

LED Mounting Spacers
Posted in Electronics & Computers, Electronics, Mechanical Components, Products, MDB on Wednesday, 01 June 2011
Keystone Electronics (Astoria, NY) has introduced a series of self-retaining, T-1 LED mounting spacers designed to assure uniform and perpendicular LED positioning. The spacers feature internal retention “teeth” that secure spacers onto LED leads, prior to assembly on PCBs. The design also eliminates the possibility of LED lead shorting by separating and retaining component leads while inserting into a PCB. The spacers feature 0.020" legs incorporated into the molded Nylon 6/6 structure to serve the dual purpose of heat dissipation and easy post-solder cleaning. Overall height of the spacers ranges from 0.120" to 0.925".

Wireless Power Generation
Posted in Electronics & Computers, Electronics, Products, MDB on Wednesday, 01 June 2011
Thermobility™ power generation technology from Nextreme Thermal Solutions (Durham, NC) uses heat as a source of electricity for low-power wireless applications. Solid-state thin-film thermoelectric technology is used to convert heat into electricity for a variety of self-contained, autonomous systems. This solution enables “wireless power” anywhere there is an adequate heat source and eliminates the need to use traditional wired power sources or replaceable batteries. When paired with wireless transmitters, it can provide electric power for decades of maintenance-free operation. The Thermobilitiy WPG-1 provides a constant voltage output of 3.3, 4.1, or 5.0 Vdc to electrical loads of 15 kW or higher. The integrated circuit board includes DIP switches for setting the output voltage.

Ultra-Miniature Converters
Posted in Electronics & Computers, Electronics, Products, MDB on Sunday, 01 May 2011
EMCO High Voltage Corporation (Sutter Creek, CA) has introduced the A Series of ultra-miniature, DC to HV DC converters that occupy less than one-tenth of a cubic inch of volume, and an extremely low profile of 0.250 inches (6.35 mm). Controllable output voltages range from 100 volts to 6000 volts. These component-sized converters are suitable for applications requiring minimal size and weight. Turn-on voltage is less than 0.7 volts, allowing for wide output voltage operating range. Use of a resonant, quasi-sinewave oscillator and fully shielded transformer result in clean, reliable high voltage conversion with low ripple, EMI/RFI and input ripple current, making it suitable for noise-sensitive equipment. A separate high impedance control pin is standard, ideal for external error amplifier control in closed loop systems or simple on/off control. Output power is 1 watt standard, with 1.5 watts available as an option. No external components or minimum load are required. Isolation is ±500V bias on the output return. Input to output leakage current is very low at less than 100 nA and coupling capacitance is

Ergonomic Connectors
Posted in Electronics & Computers, Electronics, Products, MDB on Sunday, 01 May 2011
LEMO USA (Rohnert Park, CA) has introduced the REDEL® XP Connector Series, designed using a plastic material that is resistant to sterilization. The latching system is embedded in the shell for increased impact resistance with a high contact density for medical applications, ranging from catheters to surgical instruments. It is available with four different keyways to prevent inadvertent cross connects or misconnects. The outer shell standard color is gray with an option of white or black. Backnuts and receptacle front nuts are available in seven colors for application identification. Contact configurations range from 4 to 22 contacts and can be crimp or solder type. The new design features an ergonomic grip for surgeons and medical staff.
