Off the shelf portable memory now IP67 immersion rated with EMI reduction
Nexus GB, the portable memory specialist, has released a new range of IP67 immersion 
rated and EMI reduction receptacles. The new product works with the company's memory tokens, providing OEMs with a one stop shop for harsh-environment data needs. The range can be used in military, medical, process, rail and fleet management applications for data logging as well as a range of other functions. The recently introduced receptacles are ideal for wash-down or outdoor applications where the devices are exposed to dust, water, rain, chemicals, and more.
The new series, designated SR4310, is now available in IP-65 (splash-proof), IP-67 (immersion-rated) and IP-67-EMI (immersion-rated with Electromagnetic Frequency reduction) versions.
"I think the key for OEMs is that this product is a long term memory solution," explained Michael Barrett, Nexus' operations director. "Unlike most models of USB memory or camera cards it won't be obsolete by the time an OEM has brought a design to market. This can be the crux of the issue for harsh environment applications which are often very long lead time designs."
Immersion rating is achieved using a tough outer shell that prevents dust and water from entering the OEM's electronics enclosure through the receptacle opening. EMI reduction can be added as an option by ordering the outer shell in a highly-conductive plastic.
Manufactured in the United States by Datakey Electronics, the new receptacles are compatible with the company's entire range of SlimLine memory, extended SlimLine memory and Managed-Memory tokens. The range offers four industry standard interface options and memory capacities from 1Kbit to 1GByte.
The SR4310 receptacles are panel mount devices that combine over-tighten protection and a gasket for sealing. They feature moulded-in threaded inserts to provide easy and tamper-evident installation. The receptacles gold contact points are corrosion-resistant with a contact life of 50,000 insertions or removals as a minimum. Also included as standard is a detent mechanism that both increases token retention and gives users tactile confirmation when an inserted token is physically engaged. Finally, there is a self wiping action that cleans the contacts when a token is inserted into or removed from the receptacle.
