NKK Switches'JWMW and JWLW series are IP67 rated panel sealed rocker switches with TV ratings. The smaller JWMW series features a panel cut out of 25 X 15.4 mm and is certified for TV-5. It has an electrical capacity of 10A @ 125/250V ac resistive and 10A @ 30V dc. Larger JWLW devices have a panel cut out of 30.7 X 20.5 mm and are TV-8 rated with an electrical capacity of 16A @ 125/250V ac and 5A @ 72V dc.
JWLW devices are well suited as power distribution switches for telecommunications applications. The series' capabilities exceed a 160A inrush load. These devices have an exterior seal covering the flange that is an integral part of the switch. They are rated to IP67 of IEC60529 standard, which is similar to NEMA 4 and 6. An optional watertight boot is also available. Featuring UL, CSA and VDE approvals, JWMW and JWLW switches also carry a flammability rating of UL94V-0.
All JW rocker switches are constructed for dust resistance with an interior polyphenylene sulfide seal between the actuator and contact area. These devices also feature prominent external insulating barriers which increase the insulation resistance and dielectric strength. JW housings and cases are polyamide, a heat resistant resin meeting UL's 94V-0 standards. The solder lug/quick connect terminals are molded in and epoxy sealed to lock out flux, dust and other contaminants. The terminals are also specially designed to break light contact welds and can be used with connectors.
Design engineers can configure SPST, SPDT, DPST or DPDT circuits. All single throw models can be ordered with the international inscriptions for ON and OFF. These can be specified in vertical or horizontal orientation to accommodate any panel placement needs. JW devices include an integral rocker cap available in color options of black, gray, ivory or red. Housings can be specified in black, gray or ivory.
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
