MULTIPLE CONTACT CONNECTORS TARGET MEDICAL DEVICE MARKET Incorporated into the customary HG
with push-pull latching for easy one- hand mating, and various sealing and shielding options. As an added benefit, the product
S
miths Connectors has developed the (HG) circular plastic connector
Series, aimed at the medical device market. These connectors offer a wide range of benefits including user- configurability, an aesthetic design
line is available incorporating a variety of contact technologies. The HyperGrip is manufactured with Hypertac hyperboloid contacts ensuring low contact resistance and high signal integrity. Suitable for many applications, this variation is available as an inventoried item in multiple layout configurations including: 5
(HG0), 12 (HG2), 19 (HG3), 33 (HG4), and 80 (HG6) pin positions. Applications requiring extremely
high-density configurations can be designed using Smiths Connectors’ IDI spring probe technology which more than doubles the contact density of standard connector options. Available in 1mm pitch or smaller, this technology offers a clean, sealed mating surface, outstanding tolerance of target misalignment and exceptional signal integrity.
housing, the spring probe variant of the HG Series delivers in excess 20,000 mating cycles and can be mated to simple target contacts or directly to a PCB, representing an ideal solution for disposable applications. For environments requiring
heightened electrical integrity, the HG format is available with edge card, coaxial and fibre optic (expanded beam and butt joint) technologies.

STAND-ALONE LEAD ACID BATTERY BALANCING SINGLE IC
Linear Technology Corporation has released a single IC, stand-alone multicell battery balancer for 12V lead acid batteries. Balancing works by absorbing charge from higher voltage batteries
and transferring that charge to lower voltage batteries so that all are charged equally. Charge is transferred using a lower capacity battery that is sequentially connected across the batteries in the stack. Not only does this battery transfer charge, but the energy in the transfer battery adds to the total energy in the stack, thus increasing capacity. Included on the chip is sequencing, drive circuitry for high voltage external NFETs, voltage monitoring and protection. The
LTC3305 is designed for stand-alone operation and does not require a microprocessor or other control circuitry. One battery in the stack can be replaced and quickly balanced to the remaining batteries. This device is ideal for telecom backup systems, home battery-powered backup systems, electric vehicles and industrial lighting systems. The LTC3305 employs an
auxiliary battery storage cell to transfer charge to or from each individual battery in the stack.

A new series of touch screen HMI panels has been released by Panasonic. The HM500 series consists of four models in sizes from 4.3", 7", 10.4" and 13.4" TFT colour display with LED backlight. All models can be installed in a horizontal or vertical position. The touch terminals are equipped with an Ethernet port and support VNC technology, allowing both remote VNC applications and remote assistance.
THE AGE OF THE REPLICATOR
T
he current medical device market is experiencing
significant growth, largely facilitated by IoT technologies. This is cenabling a plethora of wearable devices, remote patient monitoring and other innovations that all have in common the aim to improve healthcare and support our own awareness of fitness and lifestyle. In this month’s issue we feature a special dedicated medical electronics supplement with a focus on digital hearing aids, the latest in non-contact heart rate monitoring, along with a look at the hottest trends in the Med-tech market and an insight into the highlights of this year’s Med-Tech innovation expo.

RS Components has unveiled four MakerBot 3D printing machines. The first of the products is the fifth- generation design of the MakerBot Replicator desktop 3D printer. Key specifications of the printer include a 100-micron (0.1mm) layer resolution and a build volume of 252 by 199 by 150mm, which is an 11% larger volume than the MakerBot Replicator 2 3D printer. The second 3D printer in the range
is the MakerBot Replicator Mini, which is an easy-to-use and compact desktop machine that is ideal for use in the home or classroom. The third 3D printer in the series is
the MakerBot Replicator Z18, which offers a massive build volume of 305 by 305 by 457mm. The printer integrates an enclosed and heated build chamber designed for printing large models with minimal curling. Like the Replicator, the Replicator Z18 includes a swappable smart
extruder, on-board camera and diagnostics and assisted build-plate levelling, a 100-micron layer resolution, and Wi-Fi, USB and Ethernet connectivity. The final product is the MakerBot
Digitiser desktop 3D scanner, which provides users with a fast and easy way to create 3D models. The MakerBot MultiScan Technology allows users to scan objects from multiple angles and merge the resulting scans together to create the best possible 3D model. Outputting standard 3D file
formats, users can further shape or transform objects in a third-party 3D modelling program. The scanner offers a scan volume of up to 203 by 203mm with a dimensional accuracy ±2.0mm and a resolution of 0.5mm. Offering an approximate scan time
of 12 minutes, for each 3D model, the scan will create approximately 200,000 triangles – the number and size of which will generally determine the accuracy of the curved surfaces of an object.
