Nexus GB, the exclusive UK distributor of Datakey Electronics’ range of portable memory products, will be exhibiting at the MedTec exhibition and conference at the NEC on April 6 and 7. Nexus will be on stand 1604 in hall nine where it will show its array of tokens and receptacles for the UK manufacturing sector. Central to Nexus’ MedTec exhibition stand will be the company’s new non-volatile, reprogrammable, portable memory device that survives gamma sterilisation with no loss of data called the GammaSafe™.
The GammaSafe™ memory token contains four kilobits of non-volatile, re-writable memory. This is accessed using an SPI bus and is functionally similar to an SPI EEPROM. But unlike actual EEPROM devices, which experience data loss and even device failure when exposed to significant doses of gamma radiation, GammaSafe™ memory tokens have been proven to withstand up to 45kGy (4.5Mrad) of gamma radiation with no data loss.
Medical device manufacturers who produce single-use or limited-use disposable attachments, such as catheters, filters, tubing and medical lasers that plug in to a base controller, can now add a non-volatile memory device to the attachment, even if their attachments contain no active electronics.
In addition to the memory token, the GammaSafe™ product line includes a line of mating receptacles. The GammaSafe™ receptacles are based on Datakey Electronics' proven SlimLine™ receptacle design and are available in through-hole (GR4220PCB), surface-mount (GR4220SMT), and panel mount (GR4310 and GR4410) models. The panel-mount receptacles are available in splash-proof (IP65-rated), immersion (IP67-rated), and EMI-reduction versions, supporting a variety of medical device applications, especially those with wash-down requirements. GammaSafe™ receptacles accept both GammaSafe™ and SlimLine™ memory tokens.
“In the context of an increasingly competitive medical device market one must find creative solutions to manufacturers’ needs. Our new GammaSafe™ product range delivers on that by offering an intelligent memory token robust enough to endure gamma radiation with no data loss,” explained Victoria Barrett, Nexus’ director of PR and marketing.
The stand will also feature IP67 immersion range and EMI reduction receptacles. These products work with the company’s proven memory tokens, providing OEMs with a one stop shop for harsh-environment data needs. They have several uses in medical applications where they are ideal for devices that will be autoclaved, sterilised or washed down when in use.
