monitoring, usage history and remote control of the air conditioning. Conventional SIM cards are often the most appropriate
way to implement M2M on a product but, where space and weight are critical, a surface-mount chip SIM can be better (Fig. 3). Companies such as Giesecke & Devrient (G&D) manufacture both SIM cards and chip SIMs, and G&D’s M2M portfolio also includes highly durable and long-lasting SIM cards that are suitable for use in environments that
are more harsh than those in which mobile telephones are expected to operate (Fig. 4, see below); for example, G&D offers SIM cards that will operate in temperatures ranging from -40 to +105° C.
Fig. 3. Surface-mount chip SIMs such as this device from Giesecke & Devrient enable M2M systems to be deployed in applications where save space and weight must be saved.
We have earlier mentioned some examples of M2M applications in the automotive industry, but the costs associated with developing, implementing and operating M2M systems are reducing. Other areas where M2M is being implemented now extend from medical equipment to industrial robots, and from white goods to monitoring of food in transit (see panel). Data security is assured, as illustrated by the fact that banking systems are already using M2M technology. Although adding M2M increases product costs slightly, many manufacturers are finding that the benefits to themselves and their customers are making the investment very attractive. l
YOUR SHAFT GROUNDING SOLUTION
www.inpro-seal.com
Stray shaft currents induced by variable frequency drives can discharge through the bearings of your motor or coupled equipment and lead to premature bearing failure. The Inpro/Seal® Diverter Ring™
Current (CDR® ) uses proprietary conductive filaments to safely divert destructive shaft currents away from the bearings.
Inpro/Seal’s shaft grounding solution ships same-day, installs in minutes and is guaranteed to protect bearings against electrical damage for the life of your equipment.
We protect your bearings, your coupled equipment… and your bottom line. Circle 19 or ✔ at
