The 25th Medical Design and Manufacturing (MD&M) West conference and exposition will take place February 10 through 12, 2009 at the Anaheim Convention Center in Anaheim, CA. The MDM West conference sessions begin on Monday, February 9th and include 20 one-day sessions. The theme for this year’s activities is “Facilitating Next-Generation Medical Product Development.” For more information and registration, go to www.mdmwest.com.
Renishaw, Inc. will exhibit its new LM10 linear magnetic encoders at MD&M West 2009 in booth 4345. The device is new to the family of Renishaw rotary/angle magnetic encoders for machine applications such as woodworking, stone-cutting, sawing, metalworking, textiles, packaging, paper and converting, plastics procession, automation and assembly systems, laser/flame/water-jet cutting, and electronic chip/board production.
The LM10 linear magnetic encoder is a high-speed, high-precision device with a 100 meter measuring length.
The design features a compact, IP 68 readhead that rides at 0.1 to 1.5 mm standoff over a self-adhesive magnetic strip scale. Non-contact magnetic sensing allows the LM10 to operate in harsh environments where dust, dirt, grease, or other destructive elements restrict other optical encoders. The device is easy to install and features set-up LEDs on the readhead, wide installation tolerances, and an applicator tool for the adhesive-backed magnetic scale. The scale is available either to “cut to length” or in lengths of up to 100 m in easy to handle coils.
The LM10 is waterproof, can withstand temperatures from -20°C to 85° C, and high shock, vibration, and pressure. Non-contact, frictionless operation eliminates wear while reducing inertia for high precision at high speeds and acc/dec. The devices can be purchased as digital or analog output models. They offer customer-selectable resolutions including 1, 5, 10, 50, and 100 µm and user-selectable reference mark positions. In addition, the LM10 delivers maximum velocity of 25 m/s at sinusoidal output. Digital model positions are rated to 25 m/s for outputs at 100, 50, and 10 µm resolution, or 20 m/s at 5 µm resolution and 5 m/s at 1 µm.
Bal Conn™ Electrical Connectors for Medical Electronics
The BalConn™ electrical connector was developed in cooperation with a medical electronics manufacturer seeking to reduce package size while increasing reliability. It is an electrically conductive device consisting of a precision-engineered canted-coil™ spring retained in a metal housing.
The Bal Conn facilitates a uniform, consistent electrical connection between the lead and the battery in implantable devices used for cardiac healthcare, pain management, and sensing therapies. Its individual spring coils provide multi-point conductivity, adjusting individually to maintain maximum contact with lead electrodes that are inserted into the device header. The Bal Conn’s compact size allows for greater connector density in devices where space is limited, and its unique design eliminates the need for tools during the connection process. Bal Conn diameters are available to fit any lead configuration, from IS1 and IS4 all the way down to 0.040-in. Housing materials include 316L, MP35N® and Titanium Grade 5. Spring materials include MP35N® and Platinum Iridium (Pt-lr) 80/20. Spring insertion and removal forces can be customized to meet specific application requirements. Bal Seal Engineering’s booth is #1431 at MD&M West.
TDK-Lambda Offers New Digital Power Controller
TDK-Lambda’s new EFE Series of embedded front-end power supplies delivers industrial power density, high efficiency, and enhanced reliability. The first products in the range are the 300-watt EFE-300 and the 400-watt EFE-400 single output supplies that deliver 133% peak power capability for 10 seconds, and offer a class-leading efficiency of up to 90%. These devices will be displayed in TDK-Lambda’s booth # 373.
The EFE Series employs an eight-bit microcontroller for full digital control of the output and handles housekeeping routines. It is comprised of a 25% parts count reduction to achieve a 45% smaller and up to 56% lighter design when compared to similar products.
Compact dimensions and a 1U profile (the EFE-300 is 3-in. x 5-in. x 1.34-in. and the EFE-400 is 3-in. x 6-in. x 1.34-in.) allow the EFE Series to be incorporated in designs where space is limited, so end products can be smaller, cooler, and more feature rich. Typical applications include broadcast, instrumentation, industrial, ATE, automation, routers, servers, and security networks.
The new digitally controlled power supplies incorporate many design features including an integrated magnetics transformer that increases the overall efficiency. The digital control allows the power supply’s efficiency, such as current limit and start-up characteristics to be optimized. A low cost primary side control topology is supervised by the microcontroller, which reduces part count and increases efficiency without sacrificing load regulation performance. The need for an opto-isolator is eliminated.
The EFE-300 delivers 300 W continuous power (400 W peak for 10 seconds) with nominal outputs of 12V/25A or 24V/12.5A. The EFE-400 delivers 400 W continuous power (530 W peak for 10 seconds) with nominal outputs of 12V/33.3A or 24V/16.7A. All models can be precisely factory programmed to accommodate non-standard system voltages. An additional 12V/0.25A fan supply output is also available and all models operate from a 90-264 Vac input. Active power factor correction ensures EN61000-3-2 compliance. Other EMC design features, such as the use of SiC diodes, ensure Curve B EMC performance with a significant margin. The EFE Series is available as either open frame or enclosed. The use of low profile output connectors allow maximum airflow for optimized cooling efficiency.
All products in TDK-Lambda’s EFE Series are approved to IEC/EN/UL/CSA 60950-1 for general purpose applications and IEC/EN 61010-1 for laboratory and process control applications. The units carry the CE mark according to the LV Directive, are RoHS compliant, and come with a three-year warranty.
