Efficient heat dissipation means not wasting space for cooling. Phoenix Contact's solid-state Electronic Load Relays (ELRs) feature a large integrated heat sink at the base to deal with heat from switching high-power loads (up to 500V ac at 9A per phase). The devices can be used for motor control with inductive loads up to 4 kW or with resistive loads up to 7.5 kW without contact wear. A 24V dc signal activates the ELR switching circuit. The four types of ELRs can be wired with individual discrete terminations or ribbon-cable connectors used in the company's PLC System Cabling and INTERBUS(TM) systems. Other applications include injection molding, materials handling, and high-speed packaging. Phoenix Contact: Product Code 4311
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
